RELOADERS CORNER: Four Firings In: Final

Facebooktwittergoogle_pluspinterestyoutube

Yikes. Gremlins. Case neck “donuts” are a common development in an aging cartridge case, and it’s often unknown. Read this and know! MORE

case neck donut
Here one is! Or was.

Glen Zediker

Even if the case neck passes the “drop test,” there might be something amiss within that cylinder, and it might not show up until after case sizing, and that is the “dreaded donut.”

What exactly is a case neck donut? It’s a tiny elevated ring of brass on the interior circumference of the case neck, right at the juncture of the case neck, case shoulder. It is pretty much a little o-ring, in effect.

This “tight spot” reduces the case neck inside diameter at that point, which will, not may, have an influence on the amount of constriction surrounding a seated bullet. And since it won’t be perfectly consistent from case to case, accuracy will, not may, suffer.

And, without a doubt, there’s going to be cartridge pressure changes, which can create velocity changes. A donut is not likely to create anything like a pressure spike similar to what an excessively thickened (overall) case neck can, but it can’t be a Good Thing no matter what.

Now. I can’t say this is always a symptom of aging cases (based on the “four firings in” idea I’ve been running with). I’ve seen donuts in new cases. However, in my experience with the brass I normally use, and, therefore, that which I have the most notes on, the formation of a donut seems to coincide at the same time I measure what I think is excessive case neck wall thickening. Again, though, I spent an afternoon at the loading bench with David Tubb trying to solve donut issues he was having after one firing on commonly known “good” brass. We solved them, and more in a bit.

Culprits
There is a difference in the case wall tubing thickness at the case neck, case shoulder juncture. The neck walls are a consistent thickness — it’s a parallel cylinder (or they start off that way). At the shoulder wall thickness increases steadily in a taper as it goes down the case shoulder to then intersect with the case body walls.

There is diverse speculation about exactly what causes or creates the donut. My own experience suggests that there can be more than one factor or influence. But at the root of it is simply this difference in wall thicknesses. The difference has an influence in this area with respect to brass flow. Seems certain that there’s material movement forward from the case shoulder.

If that’s it, then the chamber dimensions (neck diameter and headspace) and cartridge case headspace play their parts. Same old: with respect to case headspace, it’s another reason to set back a shoulder the minimum amount needed for faultless function. Also old news: that’s going to be more for a repeater than a single-shot, and well more for a semi-auto.

I’ve seen it said that the expander ball or sizing button coming back up through a sized case neck “drags” the metal up with it, but also I know without a doubt that sizing without an expander means there’s a more pronounced donut. Checks I’m made sizing with and without an expander (using a neck-bushing-style die), show that an expander or, my preference, an expanding mandrel, reduces the donut influence. That, by the way, is from selecting bushings that produce the same case neck outside diameter with and without the inside neck sizing. I think the expander is just pushing it to the outside… But that’s good!

case neck donut neck turning
This helps! Turning a tiny bit off the start of the shoulder gives some relief in this area and holds off the donut for at least a while.
neck turning cutter angle
The neck turner, however, has to be configured to allow for this. Note the bevel on this cutter.

Fixing It
This one is pretty easy, after a little math at least. The most direct means is using a correctly sized reamer on a likewise correctly sized case neck, and that’s where the math comes in. The reamer should be the diameter of your sized neck inside diameter; that will pare away the donut without changing the case neck wall thickness. The idea is to get the donut without universally thinning the case neck walls, and the reason there is maintaining consistency. That, after all, is why we’re doing any sort of fixing on cases in the first place: get the same performance the maximum number of firings.

Another way, which is primarily preventative, is with an outside case neck turner, if its cutter has an angle or bevel (see photo for example). Turn down onto the case shoulder about 1/16 of an inch. Do this on new cases since that’s the only good time to turn case necks. This area is then “relieved” enough that the donut won’t form, or not for a while. In firing, this thinned area essentially relieves itself. I got this tip from Fred Sinclair eons ago and it’s the only thing I know of that heads off the donut. If you are worried about weakening a case in this area, don’t do it, but I can tell you that’s a moot worry. It’s very common practice among competitive Benchrest and NRA High Power Rifle long-range shooters. That’s how we came to a quick and permanent (well, for the short life of those cases) solution to David Tubb’s donut problems with a 6mm-.284.

neck reamer
This is a “special” reamer, meaning ordered to a custom and specific size. Choose carefully, and it’s an easy fix.

Short aside note that’s being revisited from other articles I’ve done here, but the VERY BEST way to never worry about donuts is to never seat a bullet into this area! That is the reason the better (in my mind) cartridge designs feature long necks.

Federal Court Finds California Magazine Ban Violates the Second Amendment

Facebooktwittergoogle_pluspinterestyoutube

Major 2nd Amendment boost! Judge overturns California’s ban on “high-capacity” magazines, the ban was “turning the Constitution upside down.” READ MORE

high capacity magazine

SOURCE: NRA-ILA

In one of the strongest judicial statements in favor of the Second Amendment to date, Judge Roger T. Benitez of the U.S. District Court for the Southern District of California determined last Friday that California’s ban on commonly possessed firearm magazines violates the Second Amendment.

The case is Duncan v. Becerra.

The NRA-supported case had already been up to the U.S. Court of Appeals for the Ninth Circuit on the question of whether the law’s enforcement should be suspended during proceedings on its constitutionality. Last July, a three judge panel of the Ninth Circuit upheld Judge Benitez’s suspension of enforcement and sent the case back to him for further proceedings on the merits of the law itself.

Judge Benitez rendered his opinion late Friday afternoon and handed Second Amendment supporters a sweeping victory by completely invalidating California’s 10-round limit on magazine capacity. “Individual liberty and freedom are not outmoded concepts,” he declared.

In a scholarly and comprehensive opinion, Judge Benitez subjected the ban both to the constitutional analysis he argued was required by the U.S. Supreme Court in District of Columbia v. Heller and a more complicated and flexible test the Ninth Circuit has applied in prior Second Amendment cases.

Either way, Judge Benitez ruled, the law would fail. Indeed, he characterized the California law as “turning the Constitution upside down.” He also systematically dismantled each of the state’s purported justifications for the law, demonstrating the factual and legal inconsistencies of their claims.

NRA-ILA Executive Director Chris W. Cox hailed the decision as a “huge win for gun owners” and a “landmark recognition of what courts have too often treated as a disfavored right.”

“Judge Benitez took the Second Amendment seriously and came to the conclusion required by the Constitution,” Cox said. “The same should be true of any court analyzing a ban on a class of arms law-abiding Americans commonly possess for self-defense or other lawful purposes.”

Unfortunately, Friday’s opinion is not likely to be the last word on the case. The state will likely appeal to the Ninth Circuit, which has proven notably hostile to the Second Amendment in past decisions.

Nevertheless, the thoroughness of Judge Benitez’s analysis should give Second Amendment supporters the best possible chance for success in appellate proceedings, particularly if the case ultimately lands before the U.S. Supreme Court.

In the meantime, Friday’s order prohibits California from enforcing its magazine restrictions, leaving its law-abiding residents safer and freer, at least for the time being.

RELOADERS CORNER: 4 Firings In, Part Two

Facebooktwittergoogle_pluspinterestyoutube

Cartridge cases always fail on the “next firing.” Question is which one that might be. Need to know! KEEP READING

beat case
I apologize for the image quality, but these were taken a while ago. Fortunately, for me, I didn’t have anything on hand that shows even close to the beating this one took. Cracked neck, head crack. Rare to see one case with both of the most common failures. It was attacked by an M14.

Glen Zediker

I’d always rather say it all at once, but the realities of tolerance, and space, sometimes mean I have to split a bigger topic into smaller installments. The “tolerance” part is how many pages you all are willing to scroll through!

This multi-part topic is when, and then how, to check after the progress of changes commencing with the firing on a new case. It’s the “progress of degeneration,” in a way of looking at it because the concern is getting a handle on when enough change in the brass has come about to require attention. Or abandonment. As said then, for me that’s 4 firings. That, as said last time, is when I might see changes that need attention. Also as said, that figure didn’t come out of a hat, but from my own notes in running my competition NRA High Power Rifle loads.

The areas most affected are the case neck and case head area. Case neck walls get thicker, and that was the focus last time. Well, the case head area body walls get thinner. Primer pockets get shallower and larger diameter.

As started on: Brass flows during firing. It expands, then contracts, and when we resize the case, it contracts, then expands (a little). This expansion and contraction makes the alloy harder over the entire case, but with more effect in areas of more expansion, and flow. Replace “hard” with its effect, “brittle,” and that’s a clearer picture. This increasing hardness influences its reaction to being sized or otherwise stretched. As with many metals, bend it back and forth enough times and it will break. It will also fail if it loses enough resilience, or thickness, to withstand the pressures of firing.

Case Head
When a case is under pressure during firing, the brass, like water, flows where it can, where it’s more free to move. Of course, the chamber steel limits the amount it can expand. The case shoulder blows fully forward and the case base is slammed back against the bolt face. There is, therefore and in effect, a tug on both ends — it gets stretched. The shoulder area is relatively free to expand to conform to the chamber, but the other end, the case head area, is not. Since that’s the area of the case with the thickest walls, it doesn’t expand “out” much at all. What it does is stretch.

The “case head area,” as I refer to it here, is the portion of the case above the web, which is just above the taper that leads in to the extractor groove. The “area” extends approximately an eighth-inch up the case body.

case pressure ring
Here’s a “pressure ring.” You’ll see this after firing, if you see it. And, if you see it, that case is done. The bright ring indicates excessive stretching, which indicates excessive thinning.
head separation pic
Closer view of another sectioned case. This one here was fixin to pop. 

That portion of the case does not fully expand and grip the chamber, but the area immediately ahead of it does. So the case body expands and grips the chamber, and that last little bit back to the base can and does move. It stretches. If you see a ring circling the case, noticeable because it’s lighter color than the case body, and it’s in this area, I’d say that case is done. The ring will be evident after firing, not after; don’t confuse a shiny ring around the case in this area with what can be normal from sizing, especially if it’s been a hotter load. That is pretty much a scuff from the sizing die squeezing down this expanded area.

And that’s right where a “head separation” occurs. It can crack and also blow slap in two, and that’s the “separation” part of case head separation.

This is a spot to keep close watch on as cases age. It is also the area that is more “protected” by sizing with less case shoulder set-back. That is, pretty much, where the freedom for the stretching movement in this area comes from (the case shoulder creates a gap). However! As said many a time, semi-autos need some shoulder set back for function, and it’s the reason to use an accurate gage to determine the amount of set-back needed.

case head separation
Ultra-high-precision gage, made by me. Not really. It’s a selectively bent paper clip, and running this down inside the case and and then back up the case wall can signal a dip-in in the head area, which signals thinned walls. Feel it? Case is done.

Some folks unbend a paper clip and run it down inside a case and drag it up against the inside case wall as a sort of antenna to see if they detect a dip-in near the head area, which would indicate that the wall in this area has been stretched thinner. If there’s enough to feel it, that case is done.

Since I’m working off this “4 Firings In” checklist, if you’re seeing a sign that a head separation might be nigh in that few uses, chances are the shoulder set-back is excessive, and also too may be the load pressure level.

Primer Pocket
Another case-head-area and pressure-related check is the primer pocket. As said, the primer pocket will get larger in diameter and shallower in depth each firing. As with many such things, the questions are “when” and “how much,” and the main thing, “how much?”

If the pocket gets excessively shallow, and that’s judged by a primer that seats fully but isn’t at least a tick below flush with the case base, there could be function issues. There’s a risk of a “slam-fire” with a semi-auto that uses a floating firing pin, and, if there is actual protrusion, that has the same effect as insufficient headspace.

primer pocket uniformer
A primer pocket uniformer can reset the depth of a shallowed primer pocket to what it should be, but the real test for me is how easily the next primer seats into it. If it’s significantly less resistance, I’ll say that case is done.

Shallower can be refurbished. That’s a primary function of a primer pocket uniformer. Larger diameter, though, can’t be fixed. I’ve mentioned in another article or two that, any more at least, my main gauge of load pressure has become how much primer pocket expansion there’s been. I judge that without using the first gage, well, unless my primer seater is a gage. If a primer seats noticeably easier, that’s the clear clue that the pocket is too big. Another is seeing a dark ring around a fired primer, indicating a little gas leakage.

Measuring primer pockets is a waste of time, say my notes at least. First, it’s not easy to accurately (truly accurately) measure a pocket, especially its diameter, but, that’s not really what matters. It’s how much grip there is to maintain the primer in place during firing.

I pay close attention to resistance in primer seating and won’t reuse a case that’s too easy.

Good deal on what I think is good brass, especially if you’re an AR15 loader — HERE

Yesterday’s Scandal, Today’s Mandate: Anti-gunner Embraces Operation Choke Point as Official Policy

Facebooktwittergoogle_pluspinterestyoutube

Maloney Baloney! Shades of OCP have reappeared in a re-emboldened anti-gun House majority, as well as in their media and plutocratic enablers. READ MORE

maloney

SOURCE: NRA-ILA

Last Tuesday, U.S. Rep. Carolyn Maloney (D-NY) unabashedly embraced the tactics behind one of the most shameful policies of the Obama era, openly using the guise of her federal authority to berate and not so subtly threaten a bank for lawfully serving businesses that don’t reflect her political views.

While the media did their best to protect Barack Obama and his administration from any hint of scandal, two gun related issues managed to stain the White House with considerable and widespread disrepute.

One concerned a program to secretly “walk” guns from American firearm dealers directly into the clutches of ruthless Mexican drug cartels, while at the same using the resulting violence as a pretext to call for increased firearm regulation in the U.S. The officials involved dubbed this Operation Fast & Furious. It was only the death of U.S. Border Patrol Agent Brian Terry, killed in a shootout that involved one of the “walked” guns, that finally forced the issue into the national consciousness.

The other scandal involved federal regulators pressuring banks and payment processors to sever ties with businesses that were completely lawful but that offended anti-gun sensibilities. These included members of the gun industry. This program was known as Operation Choke Point (OCP), and while no fatalities have been attributed to it, the scheme struck at the heart of the rule of law.

In the case of OCP, Department of Justice and Federal Deposit Insurance Company officials provided sworn testimony to Congress denying that regulators were pressuring banks to drop business the regulators found morally objectionable. Apparently, they suggested, the banks just misunderstood the “risk management” guidance they were being provided. In time (after considerable damage had already been done, and the banks thoroughly understood their unwritten marching orders), guidance documents were revised to “clarify” the regulators’ “true intent.”

The NRA and others have already been reporting on how shades of OCP have reappeared in a re-emboldened anti-gun House majority, as well as in their media and plutocratic enablers.

But an oversight hearing by the House Financial Services Committee on Tuesday provided one of the clearest and most shocking examples to date of how anti-gun Democrats are now willing to embrace as official policy what was still treated as scandal under the Obama administration.

The title of the hearing was “Holding Megabanks Accountable: An Examination of Wells Fargo’s Pattern of Consumer Abuses.” Wells Fargo, not coincidentally, provides banking services to the NRA.

The only witness at the four hour plus hearing was Wells Fargo President and Chief Executive Officer Timothy J. Sloan. Mr. Sloan had the unenviable task of serving as punching bag during an extended production of Political Outrage Theatre. The entire premise of the hearing was that Wells Fargo might very well have to endure yet more regulation and oversight — or perhaps be broken up altogether — unless Mr. Sloan provided satisfactory answers to committee members’ questions about the bank and its business practices.

Maloney, for her part, excoriated Mr. Sloan and Wells Fargo for refusing to follow the lead of other national banks that had refused or severed business with members of the gun industry that did not “voluntarily” adopt certain gun control “best practices” that exceed the requirements of federal law.

These practices include banning long gun purchases by young adults eligible for military service and refusing to recognize the 3-day default transfer option that gun dealers may exercise if the FBI does not complete a background check. They also just happened to mirror policy goals that anti-gun Democrats — a category that includes Maloney herself — have been pursuing through legislation they have not to date been successful in enacting.

Maloney, in other words, was not accusing Wells Fargo of having done anything illegal by transacting with members of the firearm industry. Rather, she was criticizing the bank for not imposing anti-gun rules that Congress itself has failed to adopt.

Maloney noted that Wells Fargo does have corporate “human rights” practices that in some cases exceed legal and industry standards. She then mentioned the Parkland massacre, as if Wells Fargo were somehow complicit in the acts of a deranged murderer who had nothing to do with the bank and who had been given authorization to buy the gun he used in his crime by the federal government itself via its background check system.

“Why,” Maloney demanded to know, “does Wells Fargo continue to put profits over people by financing companies that are making weapons that are literally killing our children and our neighbors? … How bad does the mass shooting epidemic have to get before you will adopt common sense gun safety policies like other banks have done?”

Given the backdrop of Operation Choke Point, Maloney might as well have asked, “Federal regulators and big city newspapers have browbeaten your competition into submission on the issue of servicing firearm industry clients. How dare you defy their wishes and continue to do so?” She also invoked the shibboleth that school shootings are increasing, a premise that research refutes.

Mr. Sloan calmly answered, “We don’t put profits over people. We bank many industries across this country.” He continued, “We do our best to ensure that all of our customers who we bank follow the laws and regulations that are in place on a local and a state and a national level.”

Maloney then interrupted, insisting that the bank’s commitment to gun control should be as strong as its commitment to human rights.

Mr. Sloan, however, stood his ground. “We just don’t believe that it is a good idea to encourage banks to enforce legislation that doesn’t exist.”

He didn’t add, but he could have, that respect for human rights also necessitates respect for the fundamental rights of self-preservation and self-protection.

The entire exchange can be seen on this video, starting at 48:03.

Needless to say, no business in America could survive if it had to comply not just with all the binding laws that regulators foist upon the country’s companies and employers but with the personal sensibilities and politics of all 535 federal legislators, plus those of thousands of federal bureaucrats.

Nor could any business survive if it had to answer for every unaffiliated person who abused or misused one of its products or services.

That is why America is often said to be a country of laws, not men. That principle has provided the most stable and prosperous economy and business environment the world has ever known.

That stability is threatened, however, by those like Maloney and others who would rule by intimidation and humiliation rather than by duly enacted legislation.

 

Activist Court Turns the Law Designed to Protect the Firearm Industry from Frivolous Lawsuits on its Head

Facebooktwittergoogle_pluspinterestyoutube

“The theory would be similar to the victim of a drunk driver suing the manufacturer or dealer of the vehicle the driver happened to be operating at time…” READ MORE

PLCAA

SOURCE: NRA-ILA

Last Thursday, the Connecticut Supreme Court created a dangerous new exception to the Protection of Lawful Commerce in Arms Act (PLCAA), a strong safeguard for our right to keep and bear arms.

Repealing or judicially nullifying the PLCAA has been a priority for the gun ban lobby ever since the law was enacted in 2005. Thursday’s decision, while not binding beyond Connecticut, provides a possible roadmap for those hoping to circumvent the PLCAA’s protections against frivolous and untested legal claims against the firearm industry.

The case is Soto v. Bushmaster. Gun control activists, however, have long sought to hold firearm manufacturers and sellers accountable for the crimes of third-parties who obtain and illegally use the guns they sell.

The PLCAA was enacted to protect the firearms industry against a highly-orchestrated and coordinated series of lawsuits that sought to either bankrupt the industry or force it to “voluntarily” adopt the sorts of measures gun control activists had unsuccessfully sought to impose by legislation.

While anti-gunners like to portray the PLCAA as providing “extraordinary” or “unparalleled” legal protection to gun makers and sellers, in reality it simply ensures that activist courts cannot create a firearm-specific exemption to well established principles of law. The most important of these is, as the Connecticut Supreme Court put it, “the general rule that an individual cannot be held liable for the conduct of others.”

Gun control activists, however, have long sought to hold firearm manufacturers and sellers accountable for the crimes of third-parties who obtain and illegally use the guns they sell. The theory would be similar to the victim of a drunk driver suing the manufacturer or dealer of the vehicle the driver happened to be operating at time.

This theory is unsurprisingly almost always a legal loser, absent unusual circumstances demonstrating a link between the merchant and the criminal or specific warning signs the merchant was aware of but chose to ignore when selling the gun to the person who later misused it.

Nevertheless, winning the cases was never really the point. The point was instead to get enough litigants in different jurisdictions to gang up on the manufacturers so that they would go out of business or give up defending the lawsuits before the cases ever got before a jury. The PLCAA was enacted to protect the firearms industry against a highly-orchestrated and coordinated series of lawsuits that sought to either bankrupt the industry or force it to “voluntarily” adopt the sorts of measures gun control activists had unsuccessfully sought to impose by legislation.

The PLCAA put an end to this, while still allowing for liability for those who knowingly engage in bad conduct. For example, it contains exceptions for marketing a defective product, entrusting a firearm or ammunition to someone unfit to have it, or breaking a law “applicable to the sale or marketing of the [firearm or ammunition],” and thereby causing the plaintiff’s injuries.

The plaintiffs in Soto v. Bushmaster are survivors and representatives of those killed in the terrible murders at Sandy Hook Elementary in Newtown, Conn. in 2012.

They advanced a variety of legal theories as to why the PLCAA did not apply to their claims.

A trial judge dismissed all of these claims in an October 2016 ruling, which we reported on at the time.

The plaintiffs then appealed to the Connecticut Supreme Court, which in a closely divided 4 to 3 ruling, found a pathway for the case to proceed.

The high court’s majority opinion focused on the exception for the violation of laws “applicable to the sale or marketing of the [firearm or ammunition]” that result in the plaintiff’s injuries.

In so doing, it had to resolve the question of whether that exception applies only to gun specific laws (like the ones used as examples in the act itself) or whether it could apply to any law that might conceivably be invoked against the manufacture or sale of a firearm or ammunition.

The court chose the broadest reading of that language, finding that it applied to any law used to bring a case against a firearm manufacturer or seller, whether or not that law was enacted with firearms in mind or even whether or not it had previously been used in the context of a firearm related claim.

The law the plaintiffs invoked was the Connecticut Unfair Trade Practices Act (CUTPA), which prohibits any person from “engag[ing] in unfair methods of competition and unfair or deceptive acts or practices in the conduct of any trade or commerce.”

The plaintiffs advanced two theories as to how this applied to the defendants’ behavior.

First, they asserted that any sale of an AR-15 to the civilian population was necessarily a fraudulent commercial practice, because (so they claimed) such firearms have no legitimate civilian use. Never mind the fact that the AR-15 is, by all accounts, the most popular centerfire rifle in America, that it is owned by millions of law-abiding people who use it for every legitimate purpose for which a gun can be used.

It is also notable with respect to this claim that Congress enacted the PLCAA the year after it allowed the Clinton Gun Ban to expire in 2004. Congress was well aware that gun control advocates hate AR-15s and similar guns and want them permanently banned, but it did not exempt them from the PLCAA’s protection. Indeed, an important principle underlying the PLCAA is that the legislatures get to determine how to regulate firearms, not the courts.

The Connecticut Supreme Court, however, did not decide whether the sales and marketing of AR-15s to the general public is inherently fraudulent, finding only that the statute of limitations had expired on that particular claim. But the court at least left the door open for future such claims in other cases. While anti-gunners like to portray the PLCAA as providing “extraordinary” or “unparalleled” legal protection to gun makers and sellers, in reality it simply ensures that activist courts cannot create a firearm-specific exemption to well established principles of law. The most important of these is, as the Connecticut Supreme Court put it, “the general rule that an individual cannot be held liable for the conduct of others.”

The second CUTPA theory the plaintiffs advanced was the outrageous accusation that Bushmaster intentionally marketed its version of the AR-15 to school shooters and other violent criminals and that the perpetrator of the Newtown crimes choose to use that gun at least in part because of this.

The supposed evidence the plaintiffs used for this claim was Remington ad copy that used militaristic images and language, appeals to patriotism, references to the gun’s use and proofing in combat.

These are, of course, the same advertising techniques used to sell any number of other lawful products to law-abiding people, from pants, to sunglasses, to boots, to vehicles. The fact that a customer might appreciate knowing that an item – especially one for use in protecting his or her home and loved ones – performed well under demanding circumstances is hardly proof that it is purposely being marketed to deranged killers.

But that premise was enough for the Connecticut Supreme Court to require the defendants in the case to spend millions of dollars defending themselves from what is certain to be prolonged and costly litigation that publicly portrays the companies and their products in the most negative ways possible.

This was so, even though the majority acknowledged CUTPA had never been used to bring a firearm-related case in Connecticut and indeed had never even been applied to a personal injury case.

And if there was any remaining doubt about where the majority stood on the issue of AR-15s, they also included a totally unnecessary commentary suggesting the limits of the Second Amendment, which wasn’t even raised as an issue in the case. In particular, the court opined, “It is not at all clear … the second amendment’s protections even extend to the types of … rifles at issue in the present case.”

To their credit, three judges dissented from the majority opinion as it applied to the ability to use CUTPA to circumvent the PLCAA, even as they indicated their own disagreement with the choices Congress made with the Act. “It is not the province of this court, under the guise of statutory interpretation, to legislate a particular policy, even if it were to agree that it is a better policy than the one endorsed by the legislature as reflected in its statutory language,” the Chief Judge wrote in his dissent.

With the viability of the PLCAA now in jeopardy, it is likely the defendants will appeal the case to the U.S. Supreme Court. Whether any intervention comes quickly enough to save the gun industry from a renewed campaign of frivolous litigation remains to be seen.

 

RELOADERS CORNER: 4 Firings In

Facebooktwittergoogle_pluspinterestyoutube

Along with all the other operations we do to them, cartridge cases also need maintenance. A good question is “when”? That’s next… KEEP READING

old case

Glen Zediker

I tend to write much of what I do for those who reload for production. Those are folks expecting good utility in exchange for the expense and effort: a reliably-performing round of ammunition, over and over again. They’re loading and reloading because they like to shoot. It’s a big bonus to most, and I include myself in this group most of the time, if that good performance comes with a minimum of effort. Clean, size, prime, fill, seat, shoot. Five steps to get to the one thing that matters most: shoot! I am also in another group some of the time, not as often now as I once was, and those folks may add a few more steps before getting to the “shoot” part (case prep mostly).

It would be wonderful if that simple cycle endured without end. But it won’t.

Overall case condition after X-many firings varies A LOT because of a lot of factors, variables. What matters is getting a handle on it. I look over each case each time I load it, but I don’t break out the measuring tools. That’s not neglect. There is never (ever) any excuse for neglect. That’s not what this is about. It’s about working out a responsible, reasonable, and realistic schedule for when to take a close look at the progress in condition that new batch of cartridges cases has followed after some time.

In my experience, which is what’s in my notes, I say that’s 4 firings.

I went through the per-use checks enough times to know the schedule one brand and lot of brass, used with the same loads in the same barrel, follows with respect to changes. And by that I mean when changes require attention. I’m also starting with prepped cases, including trimming, before their first firing.

Let me make clear that I’m not suggesting that 4 firings is maximum case life! What I am suggesting is that this is the point where it’s likely to see measurable influences from use and reuse, and, as such, that it can be measured. That’s what we’re after now: take a check to see what’s happening, and that also is a big help toward getting clues about where and when these changes might get noticeably influential.

So, to be clear: the case has been fired four times, reused three times. Next loading, if there will be one, will be for the fifth use.

chamber reamer
We, or more correctly, our cases, are at the mercy of this thing: a chamber reamer. It sets the amount of space the case can expand into.

Changes
Continuing to use and reuse cases, we’re not really using the same cases each time. The cases change, and much of the change comes from material flow, which is brass.

Here’s how it goes, which is to say here’s how it flows: Case neck walls get thicker. The case head area body walls get thinner, over a short span of the body. Primer pockets get shallower and larger diameter. Overall, the alloy hardens over the whole case.

As gone on about a few times in this spot, there’s going to be more change in cases run through a semi-auto than those used in a bolt-action. That’s because of the necessarily additional (comparatively speaking) sizing and also the additional stress resulting from the firing cycle. There’s more flow because the cases are free to expand more.

drop bullet
A simple, and important, test to check if case necks walls have thickened excessively is to take a fired case and drop a bullet in it. If it won’t drop without resistance, stop! That’s way too much.

The Neck
All case necks expand to whatever the chamber allows. There’s no relationship between that and sized dimension because, clearly, there has to be a small enough neck inside diameter to retain the bullet. It is, though, one of the reasons case necks tend to give up quickest (plus it’s the thinnest-walled area on a case).

The case neck is my primary concern, and the first thing I check. If the walls get too thick it’s possible to cut the space too close between the case neck and the case neck area in the rifle chamber. There might be interference upon bullet release, and that creates excessive pressure, or sure can. All that depends on what the chamber allows for expansion room.

The most simple check is to see if a bullet will freely drop into a fired case neck. If it won’t, stop! Do not reuse that case as-is. A case that won’t pass this no-tool test has excessively thickened.

Somewhere in your notes should be a figure indicating loaded outside case neck diameter, on new brass. This dimension is exclusive of the sized neck diameter, because when the bullet is seated the neck is going to expand to accommodate the bullet. Another check of loaded outside neck diameter will show if there’s been thickening. If an inside neck sizing appliance is used (a sizing button), then that will tell you also, comparing it to what you also recorded for the new case after sizing it. (And it’s a good reason to always run new brass through your sizing die, even if it’s “ready to go” out of the box.)

I hope it’s clear enough why it’s important to “write everything down.” References, standards are big helps.

Direct checks of the neck walls themselves using a suitable tool will show thickening. However! Case necks don’t necessarily thicken the same over the entire height of the case neck cylinder. Remember, the brass is flowing so moves in a direction, and that part of the case has a wave going forward, toward the muzzle. There can and likely will be a tapering from thicker to thinner. Measure at more than one point.

Safety is one thing, and the most important thing, and then the other thing is accuracy. Case neck “tension” needs to be consistent from loading to loading to get reliable accuracy.

Fixing it? An inside case neck reamer is the easiest and most direct means. However! Make double-dang sure you know the numbers and therefore how and at what point to use it! Many are intended for use on fired (not yet resized) necks. Others are a specific dimension that you may or may not be able to specify. Thinning the case neck walls using an outside case neck turner is another direct remedy. A little tedious.

forster reamer
The best way I know to remove material to refurbish overly-thickened case neck walls is an inside case neck reamer. This is a Forster, designed to work with their case trimming base. Trick is knowing the case condition it was designed to be used with. This one is dimensioned for use on fired, unsized case necks (it’s 0.003 under bullet diameter). Run it on a sized neck and way too much brass comes off. Various sizes are available.

Reamer or turner, though, this job hasn’t finished until the refurbished case has been run through your usual sizing die, and checked again for diameter.

Well, so much for this here and now. Out of room! More next time…

RELOADERS CORNER: Choosing Your Brass

Facebooktwittergoogle_pluspinterestyoutube

It’s not all the same! Depending on needs and application, there are three decisions that can have an impact on your satisfaction. READ MORE

norma brass

Glen Zediker

Last time I offered a few ideas on loading the same cartridge for use in different rifles. Essential message in that was, in one word, “compromise.” There’s some give and take when we’re trying to please more than one at time, as such is life…

Choosing cartridge cases is a little, to a lot, the same. Different rifles, different action types, different uses, different budgets, all suggest input that helps determine what works best, all around.

There are three things to consider, maybe four.

One is the action type. Semi-autos need “tougher” brass. That, overall, means “harder,” not necessarily thicker. Due to the resizing requirements for good function, which means a little “more” in all areas, there’s likewise more expansion in each subsequent firing. Brass made of harder alloy is less, not more, susceptible to failures — by my experience. Considering the elastic and plastic properties of brass, harder exhibits a little less effect from each.

I prefer harder composition brass for a bolt-gun too. Most NRA High Power shooters do. Reason? It runs better! There’s less “stickiness” in running the bolt for rapid-fire events.

Two: case capacity. They are not nearly all the same! My experience has shown me that more capacity is better, and that’s especially if we’re wanting to edge toward max-pressure loads. Even though the pressure generated inside the case using more (larger case volume) or less (smaller volume) may get to the same level, there is usually more net velocity (at the same pressure) when there’s more room in the case. If it didn’t matter then other things done to expand case capacity (like shoulder angle changes) wouldn’t matter either.

cartridge case capacities
Case capacities vary, and, as you can see, a good deal. These .223 Rem. are each filled with an equal amount of spherical propellant.

Three: Precision standards. What do you expect, what are you willing to do to get it? After enough experience with enough different brands, that is a legit question. Some brass is “better” out of the box. Cost usually reflects on initial quality. Paying a premium for premium quality, which is three things: consistency, consistency, and consistency. That consistency will primarily, or at least measurably, be in wall thicknesses. The choice there is to buy it or make it. That choice is a balance between effort, value of time, and proven results.

lapua brass
Consider first-use or re-use? Good stuff! And you’ll pay for it! Lapua cuts case prep down to sizing: the case heads are milled, the primer pockets and flash hole are reamed. It’s also a little thick and a little soft. Single-shot-style use in a bolt-action, can’t really beat it, but my AR15 Service Rifle beats it to death.

After using enough different brands with varying levels of costs and claims, I think the most honest thing I can tell you is that you’ll likely end up with the overall “best” brass case you can have shopping in the middle, plus a little, and then getting to work on it. A good commercial “name” brand can be made at least effectively close to the dimensional equivalent of a premium brand, like Norma, but it’s not without effort.

Before spending any time weighing or otherwise sorting cases, do all the prep work you plan beforehand. If any prep involves material removal, even trimming, that influences weight accuracy and, therefore, the viability of segregation by same.

Recommendations?
Yes. And no.

About the time you decide there’s some certain way some certain thing is, they up and change it. I avoid making too many lumped-together, generalized statements about particular brands because of that. However! I can tell you that some of the “better” brands of brass also tend not to hold up as well, or won’t if there’s much working load to load (expansion, sizing). I’m thinking here of the better-known European brands, like Norma and Laupua. Those are near about dimensionally flawless out of the box, but they tend to be a little on the thick and soft side. I use Norma in my .22 PPC because the cost is worth it. If I drive from Mississippi to New Mexico to shoot a match, that’s the least of my expense.

nosler brass
This isn’t cheap either, but I have had good results with it. Nosler is, or can be, ready to go out of the box, including case mouth chamfer. It’s held up well for me in semi-autos.

This is also the reason that every serious competitive shooter I know says to buy up as much of one lot as you can, if you know it’s good stuff. That’s for all components.

Sometimes brass chooses you!

As said last time on the “Multiple Gun” loads, if you’re mixing brass things like case volume do factor. As also suggested then, the best solution is to pick a load that’s in around the 80- to 90-percent range of max. I mix brass all the time. I shoot quite a lot of factory ammo and, yes, I save each case we can retrieve. I clean them all, size them all, and fill them with a “compromise” load I worked up for can blasting. The need for those excursions is not quarter-minute precision.

If you’re looking to save as much as you reasonably can and still get “good” cases there’s honestly nothing wrong with Lake City. The more recent production 5.56 measures pretty well, and it’s tough, and relatively high-capacity. I sho can’t vouch for any other headstamp on mil-spec ammo beyond “LC.” However! I suggest purchasing it prepped. Avoid “range dump.” A big issue with once-fired is which chamber it was first-fired in. Avoid .308 Win. (7.62 NATO)! You DO NOT want to deal with M60 or Minigun leftovers.

lc nm brass
This is LC Match 7.62. No primer crimp! For reuse in a semi-auto, it has the right stuff, which means made of the right stuff: it’s hard, tough.

RELOADERS CORNER: Multi-Rifle Loading

Facebooktwittergoogle_pluspinterestyoutube

If you shoot the “same” load for different rifles, here’s a few ideas on getting the most out of it for all of them. READ MORE

multigunj reloading

Glen Zediker

I have a few rifles…

Every time I do a new book I have more. This last time around, in writing America’s Gun: The Practical AR15, I built 10 AR15s, and half of those have the “same” chambering (5.56 NATO). My choices that I can case and then uncase any afternoon for some range time might all have the “same” chamber but they’re each and all, in some measured amount, different.

That’s literally in measured amounts, and more in a minute.

If you (like me) really don’t want to load separately, store separately, and use separately, then the only real choice is to employ a “lowest common denominator” tactic. With only one exception, I don’t load uniquely for any of these guns. I pretty much just want a sack-full of ammo at the ready. The one I load uniquely for has a tuned gas system (it’s a practical competition “race gun”).

old and new AR15
Both straight up NATO chambers, but the little one won’t run what the big one will. It’s a gas system architecture difference, and a little more challenge to find a “universal” load. Rifle-length gas systems like on my retro “602” M16 (left) are, by the way, more tolerant of load variations than tricked out short guns like the brand-new USASOC URG-I (right).

Variables
Assuming all the rifles have the “same” chamber, meaning only that the barrel stamp is the same, there still exist differences. There are differences reamer to reamer, and, depending on the operator, there might (will) be differences in headspace, and leade. They’re likely to be tiny, but tiny can matter. Some manifestations of pressure have some to do with the barrel bore (land diameter for instance).

I measure spent cases for all the different rifles. They don’t measure nearly all the same! Of all the set-by-sizing dimensions, cartridge headspace has shown the most variation in my samples.

That, also, is a very important dimension to set. As gone on (and on and on) in RELOADERS CORNER, the idea is to get adequate case shoulder set-back to ensure function, and also to keep it to the minimum necessary to prolong case life. The minimum necessary runs from 0.003 for a semi-auto to 0.001 for a bolt-action.

To set this dimension for multiple rifles that use the same batch of ammo, the means is pretty easy to anticipate: find the gun with the shortest headspace, set the die to set back the case shoulder where it needs to be for that one, and live with it.

If you don’t want to give in thataway, but rather prefer (or at least don’t mind, two technically different outlooks) running multiple dies with multiple adjustments, and keeping the ammo segregated, then here’s more.

I’ve had really good experiences using a turret press. For most rifle needs, one with, say, four spots will allow the use of two sizing dies, maybe three (depending on what occupies the other locations). These dies can be uniquely adjusted for cartridge case headspace. Of course, it’s easily possible to just swap dies in and out but the turret keeps them put and saves a step.

redding t7
A turret press is a sano solution to maintaining differently adjusted dies. Redding and Lyman both make good ones. This is a Redding T7.

If you’re a bolt-gun shooter and have a couple or more rifles that run the same cartridge, and if you’re wanting to get the most from your efforts in loading for each, you might consider this next. Redding has long-made a set of five shellholders with varying heights. They allow a shellholder swap on the same die to alter case headspace, for example. There are also shims available that go under the die lock ring to provide for die body height variance. This sort of setup lets the handloader alter-adjust headspace without readjusting the die.

redding shellholders
Redding Competition Shellholder set. Five shellholders, each 0.002-inches different heights. This allows, for one, different case shoulder set-back using the same die as set.

Levels
Now. As far as lighting on a load that they’ll all shoot their absolute best with. Sorry to say, but “not likely.” There sometimes seems like there is more mystery than there is known in “why some shoot better” with one load. And when I say “load” I’m talking about the dose, the amount of propellant. What that ends up being mandates at least some effort in evaluating more than one rifle when working up to a point you’ll call it “good.”

NATO-spec ammo is hot and getting hotter! I’m talking about true NATO-spec, not just lower-cost ammo sold in a “plain box.” This isn’t about NATO ammo, but it was for me. The difference between pressure levels of NATO and, say, a commercial-made .223 Rem. “match” load are enough that two of the guns won’t even run with that. I set up these guns from the workbench respecting NATO pressures, and that, in most cases, meant firming up the “back end”: heavier buffers and springs.

My good old “do it all” load no longer exists in my current notes. Amazingly, to me at least, it’s up the velocity equivalent of about a grain and a half from what I used to bust up clods and cans with. It’s also a different propellant (now H335).

No question: pressure symptoms must also define the “lowest common denominator” when loading the same for multiple guns. Since I also have to consider reliable function in my own example, and as just suggested, I’m loading up a little nearer the edge. I carefully evaluate spent case condition from each rifle and anything that reads or appears remotely as an excessive pressure sign means I’ll knock a universal half grain off the group load.

Washington: Magazine Ban & Firearm Seizure Bills Pass Committee

Facebooktwittergoogle_pluspinterestyoutube

Getting it cranked up early this year folks! Proposed legislation in Washington state seeks to ban higher-capacity magazines. READ IT ALL

magazine ban

SOURCE: NRA-ILA

During the executive session last Friday, the Washington state House Committee on Civil Rights & Judiciary voted to pass House Bill 1068 to ban many standard capacity ammunition magazines and House Bill 1225 for firearm seizures without due process. These two bills will now go to the House floor for further consideration. Please contact your state Representatives and urge them to OPPOSE House Bills 1068 & 1225.

House Bill 1068, sponsored by Representative Javier Valdez (D-46), was filed at the request of Attorney General Bob Ferguson and passed by a vote of 9-6. It would ban the possession of ammunition magazines with a capacity greater than 15, encompassing the standard capacity magazines for many handguns and rifles commonly owned by law-abiding citizens for self-defense.

House Bill 1225, sponsored by Representative Laurie Jinkins (D-27), would require law-enforcement to seize firearms and ammunition when they are called to the scene of an alleged domestic violence incident and hold them for at least five business days. This would result in property being confiscated without first going through due process and subject citizens to bureaucratic red tape to get their property returned.

House Bill 1739, sponsored by Rep. Valdez, was also filed at the request of Attorney General Ferguson. It would end the centuries-old practice of manufacturing firearms for personal use and also contains provisions that go above and beyond federal law that already bans undetectable firearms. The committee rescheduled the vote for HB 1739 to next week.

Contact your state Representatives and urge them to OPPOSE House Bills 1068 & 1225.

 

RELOADERS CORNER: Life in the Fast Lane

Here are a few tips for getting the most, the easiest, from high-velocity semi-auto .224s. READ IT ALL

22 nosler

Glen Zediker

Here’s the conclusion of my “trilogy” on the movement of .224-caliber rounds into the left lane of rifle cartridge choices. The focus last time was on the 22 Nosler and .224 Valkyrie, and here are some ideas on making the most from either, or another similar.

First: Getting high (higher) velocity is really not rocket surgery: make the bullet smaller and the case bigger. Rounds like .243 Win. showed that clearly. However!

Speed, greed, need, (and heed)
Higher and higher velocities bring about a “debate.”

After messing with all this for decades, there are two things I know for sure about bullet velocity: more velocity shoots better; more velocity shoots worse. But! It’s not velocity itself. It’s a common belief, and totally plain wrong (and wrong-headed), that lower-velocity shoots better groups. It’s also wrong that higher velocity shoots better groups. Working with one cartridge and one bullet, for example, I’ve had plenty of times when the faster the bullet went the better it shot, and the slower the bullet went the better it shot. That’s all to do with the “combination” of the propellant and bullet and barrel and son on and on and on. Point is: it’s way on better to find a combination that shoots better and better the faster the bullet goes. That didn’t have a lot to do with the point of this, but it is important to keep in mind — velocity is not evil.

I know I don’t have to go into benefits of higher velocity. Hard to argue with those. What I do want to go into is a look at how much more and at what cost. Virtually every downrange improvement has some sort of cost. The cost of higher velocity is barrel life, mostly.

As said, higher velocity comes from more propellant. More propellant produces more flame and more gas. There’s a term, “overbore,” that gets around in discussions of, usually, large cartridges, like magnums. It actually is a mathematical device that compares the barrel bore area to the cartridge case volume. It is “V” (case volume) over (divided by) “A” (barrel bore area) and the answer, “O,” is therefore a ratio. The bigger O gets the more overbore the combination is. Applying that, something like .243 Win. is overbore. That’s also why a barrel chambered in that round lasts no more than 1200 rounds at true peak accuracy. That round is not considered overly powerful by anyone I know, yet, has the same sort of (bad) effect on barrels as does something like a .300 Win. Mag.

As said last article: clearly, barrel life in Nos. or Valkyrie is going to substantially shorter compared to .223 Rem.

Suggested Mods
Higher and higher velocities also come from varying propellant choice. Specifically, slower-burning propellants literally fit better into higher-capacity cases. Recollecting back on something I’ve mentioned umpteen times in these pages: propellant burning rate has a whopping lot to do with semi-auto manners. Slower-burning propellants elevate gas port pressure, which brings on the “over-function” symptoms, none of which are good. There’s a comparison of 22 Nosler with .22-250. They’re similar in structure. General consensus is that a favored propellant in the .22-250 is H-380 (if you don’t like that one, and I don’t, it’s going to be another in that burning-rate range). So. Point: 22 Nos. and Valkyrie do not get the most they can get from a “safe” .223 Rem. propellant (I break that off at nothing slower than H-4895). For good instance, I run Varget in my Nos. and that’s the same propellant I run in my PPC. It’s a little too slow, my opinion, for a stock gas system in an AR15.

Most running a 22 Nosler or .224 Valkyrie are looking to exploit speed, so will, therefore, be shopping or specifying 24-inch barrels (that’s a “standard” available length). That, combined with a standard 12-inch “rifle” gas port location, will, not can, escalate pressure within the gas system. That combination also puts a .223 Rem. over-pressure. (Reason is that the post-port length add increases “dwell-time,” which is the duration that the gas system is containing maximum pressure.) The best solution to excessive port pressure is to move the gas port! “We” (competitive High Power Rifle shooters) have been doing that for better than 20 years.

Yardstick: Plus-1-inch for .223 Rem. and plus-2-inches for Nos or Valkyrie. That makes a huge difference! Of course, this mod is only possible if you’re going with a custom barreling op done by a competent and savvy builder.

long gas tube
More gas and a longer barrel team up to over-charge the gas system. The best initial solution is to get your barreler to move the gas port forward (which means custom parts). No step for a stepper! Custom tube shown with standard rifle-length (top).

Without that, there are two options that, I say, should be used in tandem: a valved gas block and increase buffer/spring mass and resistance. The adjustable block reduces the amount gas that gets into and is contained within the system and the other offsets the effects of the harder hit the bolt carrier group will be subject to.

odin adjustable gas block
An adjustable gas block will, indeed, work to reduce excess gas pressure. There’s going to be erosion in the mechanism, though, so over time it’s going to change in its function. My personal favorite is the Odin Works, and one reason is that it’s rebuildable.

odin adjustable gas block

I am a bigger fan of the “architectural” solution rather than the adjustable gas block. They won’t last forever…

Another important spec I want to hit on: barrel twist rate. As said last time, the .224 Valkyrie was, so they say, designed to handle the biggest of the high-bc .224 bullets and, specifically, the Sierra 90 MatchKing (and similar). That’s why, as also said last time, commonly offered twist rate with that chambering is 1-7. Folks, 1-7 isn’t enough, in my experience, for 90+ .224 bullets. I (“we”) use 1-6.5 twist for 90s and the others in 20-inch barreled Service Rifles (.223 Rem.). That’s quick. Those shoot 77gr “magazine” bullets really well also. With Sierra now offering a 95gr .224, go with a 6.5. The extra velocity from Valkyrie and 22 Nos does indeed boost rotation, but I strongly suggest not relying on that promise for stability. It’s edgy.

sierra 95 SMK
Dang. An SMK 95gr .224… 27-caliber ogive! Best get some spin on this bad boy. I recommend a 1-6.5. Experience has been that 1-7 is borderline adequate for any bullet in this length range, and I’m not a fan of borderline, or “adequate.”

1-6, by the way, tends to blow up bullets.
