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.

The Unequivocal Instrument: Snubnose Magnum Revolvers

Facebooktwittergoogle_pluspinterestyoutube

While the revolver is often looked down on as old technology, few handguns are as reliable and accurate as the short-barrel .357 Magnum revolver. KEEP READING

ruger sp101 357

Wilburn Roberts

With the great and growing abundance of concealed carry permits as Americans exercise their rights and commons sense, and with a present political climate that nurtures such progress, armed citizens are choosing to be responsible for their own safety. Choosing which handgun may be an easy enough choice for seasoned shooters, but quite a few of the new generation of handgunners are newcomers to one handgun in particular…

Many are steered toward a handgun that doesn’t fit their skill level. A semi-auto 9mm or .40 compact isn’t for everyone. However, the novice and very experienced shooter alike often choose a revolver. They are well armed when they do so.

snubnose revolvers
Short barrel revolvers are great personal defense firearms. Be certain to train well!

The snubnose .38 Special is a reasonable choice, however, the snubnose .38 is seen as less powerful than the 9mm pistol. (A “snubnose” is generally defined as having a barrel length 3 inches or less.) This is overcome by the power of the .357 Magnum revolver. When comparing the types, the advantages of the revolver have to be plain to make the short-barrel revolver an attractive choice.

Reliability is one advantage.

A further advantage of the revolver is that the revolver can be fired repeatedly even if it’s contacting an opponent. The semi-auto would jam after the first shot. It may also short cycle due to a less than perfect grip.

taurus 605
This Taurus 605 .357 Magnum revolver is carried in a 3Speed holster. This is a great deep concealment rig.

For a weapon to be used at conversational distance, the revolver’s reliability in this scenario is a big plus. A further advantage would be in a struggle for the gun — and this happens often — the gun grabber has little to hang onto in the case of a short-barreled revolver.

As said, an alternative to the .38 Special is the .357 Magnum. The .357 operates at almost three times the pressure level of the .38 Special. The Magnum operates at some 40,000 copper units of pressure compared to 18,000 for the .38 Special, and 20,000 for the .38 Special +P. This gives the magnum a great advantage in power, and the ability to use heavier bullets. There are .357 Magnum revolvers almost as compact as the snubnose .38, but often the Magnum will have a heavier frame and a heavier barrel which offers a better platform for the more powerful cartridge.

galco holster
Galco’s Carry Lite revolver holster is among the best for concealed carry. This inside the waistband holster is affordable and available.

These handguns also willingly chamber the .38 Special, providing a power level option in the same gun (that’s not available in a semi-auto). A .38 Special +P load is a good choice for the beginner for use in his or her .357 Magnum revolver. The shooter may move to the Magnum loadings after sufficient practice.

The obvious mechanical advantages of the revolver as related to reliability, the ability to use the weapon with a less-than-perfect grip and at point-blank range, are compelling sales features. However, in the end, the ballistics might be the best selling point. There has been a myth circulated for some time that the snubnose .357 Magnum is no more powerful than a .38 Special, as the Magnum loses velocity when fired in a short barrel. This is far from true. The Magnum does lose velocity when fired in a 2- to 3-inch barreled compact revolver, but it remains far more powerful than the snubnose .38 Special as the accompanying table shows. The .357 Magnum considerably outperforms the .38 Special by any measure.

With these revolvers, recoil could be grim to the uninitiated. Recoil energy approaches 12 pounds in some .357 Magnum revolvers, compared to 6 to 8 pounds in the 9mm and .40 caliber handguns, and a slight 4 pounds with .38 +P ammunition in a snubnose. This is a sharp jolt not to be underestimated. The person deploying this revolver must engage in practice and use the proper techniques to master this revolver.

sp101
The Ruger SP101 in .357 Magnum is among the strongest handguns — ounce for ounce — ever built.

Modern .357 Magnum revolvers such as the 5-shot Ruger SP 101 are designed with every advantage toward making the gun controllable. The factory grips on these revolvers are among the best ever designed. If you are able to find a Smith & Wesson K-frame revolver at a fair price, the 6-shot Smith & Wesson is even more controllable, albeit a bit larger.

Use a proper holster such as one of the Galco inside the waistband holsters and you will find the snubnose revolver very concealable. The revolver is simple to use — simply draw and fire. The Ruger and Smith & Wesson each have smooth double-action triggers that promote accuracy.

Another advantage of the revolver is superb accuracy. The Smith & Wesson Model 19 I often carry has been in service for four decades. A combination of excellent high-visibility sights and a smooth trigger make for fine accuracy. As just one example with the .38 Special Fiocchi 125-grain Extrema, this revolver has cut a 1.5-inch 25-yard group for 5 shots.

The .357 Magnum revolver isn’t for everyone, but for those who practice, one offers excellent accuracy, reliability, and proven power.

HANDGUNS: 10 Minutes of 10mm History

Facebooktwittergoogle_pluspinterestyoutube

Many-time champion Rob Leatham gives his take on one of the most powerful semi-auto loadings. Listen! HERE’S MORE

springfield armory 10mms

SOURCE: Team Springfield, Rob Leatham (find Rob on Twitter)

The 10mm auto is a curious cartridge.

Designed originally as a best-of-all-options for the defensive pistol world, it was targeted to be an all things to all people service pistol cartridge. Sort of a hybrid of the service pistol standards, .45 ACP and 9×19 rounds. The goal? To have more capacity than the .45 and be more powerful than the 9mm.

Without completely retelling the detailed history, in the early 1970s, the late Col. Jeff Cooper was reportedly looking for a round that combined the advantages of both velocity and momentum. The ballistics of a 200 grain .400 (10mm) diameter bullet traveling 1000 feet per second looked good to Jeff on paper.

CASE CREATION
There was a problem, however. There wasn’t a readily available cartridge case for an auto pistol that would handle that bullet diameter. So it wouldn’t be as simple as just powering up an existing cartridge as had been done with .38 Special, .38 Auto, and .44 Special.

A new case had to be devised. Well, maybe not new, but altered and repurposed.

Similar “wildcat” cartridges had been developed previously using .224 Weatherby and .30 Remington brass. These had been chambered in a number of different guns. Most promising was the .40 G&A round developed by Whit Collins, followed shortly thereafter by the Centimeter and then the .40 S&W.

Of those, only the .40 S&W would ever make it into production, albeit much later, but the ground was laid for the 10mm as we know it.

10mm

BREN TEN
When the design of this new hybrid cartridge occurred, a new gun (with design input from Colonel Cooper) was being developed to accept it. Known as the Bren Ten, it was basically a sized-up CZ 75.

Both the 10mm gun and round were in development about the same time. However, the ammo was finished long enough before the gun that people were becoming impatient to try this new hybrid.

WE HAD AN INTERESTING NEW ROUND AND NOTHING TO SHOOT IT IN.

So, what to do? The combat pistol world was in its hey-day and the buzz over this new combination was eagerly awaited by pistol enthusiasts worldwide. As time dragged on and the Bren Ten didn’t seem to be happening, Colt stepped in and introduced a model to accept the 10mm. While familiar, it really wasn’t the totally new, complete package we were all hoping for.

AMMO ADVANCES
Remember that the design goal was originally to achieve a 200 grain bullet at 1000 FPS. This would deliver a flatter trajectory, greater penetration with a slightly higher level of power in both energy and momentum than standard .45 Auto (with the bonus of increased magazine capacity).

Norma, the company that originally developed the 10mm, in their enthusiasm to make the round as good as modern propellants would allow, made their ammo far more powerful than was originally requested. The ammo was approximately 20% higher in velocity than the original specifications called for. While this sounds like a good idea, it was in fact not. At least not for service-pistol use.

With that increase in power came costs that were just not worth it for the majority of shooters.

While exceeding the power of any other standardized auto pistol combination encountered, the gun/ammo combination was just too difficult for most to control.

To add to the overall problem, the Bren Ten Pistol was long delayed and in the end, sadly never made it. Some were built, but they too couldn’t take the beating of the “hot” Norma ammo. Other manufacturer’s 10mm guns did not deliver on the promise the 10 had made. They were harder to shoot than .45 in the same platform and did not hold up well to the very high-pressure ammunition.

So for most shooters, the existing 1911 platform pistol with the powerful 10mm ammo just didn’t offer enough benefits to replace the already-available and time-tested .45ACP.

Springfield Armory 10mm

10MM TIMEOUT
With no viable new gun, the high expense of ammo, and the excessive recoil that made it hard to control and shoot, the 10mm never became as popular as was hoped. And it mostly vanished from the public eye.

But it didn’t die.

Although too hot for most applications for a service pistol, the 10mm with its potentially higher power levels continued [slowly] to make friends in the civilian and law enforcement world. A lot of shooters still wanted a 1911 with more velocity, penetration, momentum, energy, and flatter trajectory than the .45 offered. The 10mm’s devout but small following, by those who recognized its niche, soldiered on.

FBI CONNECTION
The FBI adopted the 10mm after the infamous 1986 Miami shootout, where they unfortunately discovered that they needed more gun, power, and firepower than they currently had.

The bureau soon concluded after the adoption, that existing 10mm ammo was “too hot” and as a result, requested a special lower-pressure load developed for them. This new load didn’t exhibit the same problems the original hot 10mm cartridges did, and proved a good compromise between power and controllability.

This ammo was more inline with the original request. Due to the FBI adoption, the 10 was back in the limelight and major loading companies jumped on the band wagon.

Since then, the 10mm has continued to exist for both gun manufacturers and ammunition companies, albeit not as a best seller. I sense a change in the air though…

SPRINGFIELD ARMORY 1911 TRP 10MMS
Springfield now produces their top-of-the-line TRP in 10mm in both a 5-in. and long-slide 6-in. model.

But wait, what about all the 10mm problems of gun wear and tear and hot ammo?

Better materials, 10mm-particular specifications, and improved manufacturing capabilities allow us to produce superior, more-durable 10mm pistols. Specifically, one that will withstand the force of the “hot stuff” and still work with the lower pressure “standard ammo.”

Flat out, the Springfield 10mm pistols are better than any previously available models from any manufacturer.

The only thing that could make our 10mm TRPs better, is if they were easier to aim. #OldEyes

springfield armory optic 10mm

MEET SPRINGFIELD’S 1911 TRP 10MM RMR
With the Trijicon ACOG® RMR® optic sight, this 1911 offers the ballistic advantages of the 10mm round in a strong, accurate, durable package with the latest in optical sights.

For many shooters, aiming is difficult. Some eyes just don’t see that well. While vision issues can be resolved with glasses or contacts, there is almost always a compromise. You can correct vision to either the sights or the target, but one of them is NOT going to be in focus.

Optical sights allow focusing on the target. You never have to refocus back to the gun to align the sights. Seeing all the elements of a good sight picture clearly is no longer difficult. Look at your target and the dot is superimposed, showing the potential impact point of the round. The old argument of whether to look at the sights or the target no longer applies. Everything is in focus.

The 10mm is the most powerful round commonly available that fits the 1911 platform. It can be a viable “all things to all people” chambering.

For you speed junkies, the 10mm offers high velocity. Some loadings have bullets going upwards of 1300 FPS. This guarantees high energies and flat trajectories.

For the big-and-heavy-is-better guys, the 10mm bullet is .400 inch in diameter and regularly available in 200 grain weights. So it’s a perfect fit for those who like the old saying, “I don’t care what caliber it is as long as it starts with 4.”

So thanks to all you stalwart 10mm fans, a purposeful caliber has survived and will continue to thrive into the future.

CCW: Avoiding Reloaded Ammo?

Facebooktwittergoogle_pluspinterestyoutube

Many handgun owners reload, but is it wise to count on that ammo for defensive carry? Jason Hanson says “no.” READ WHY

handgun bullets

Jason Hanson

During war, one of the most common tactics used to fight the enemy is to disrupt their supply lines.

During the Vietnam War, U.S. soldiers did this in a different way than just simply stopping supplies from getting to the enemy.

This specific operation, code named “Project Eldest Son,” was carried out by U.S. Green-Beret patrols, who captured enemy ammunition stashes that were typically 7.62 X 39mm ammo cartridges, which were used in the AK-47’s regularly carried by Communist forces.

Once the U.S. captured the ammo stashes, the cartridges would be disassembled and then put back together with different components.

For instance, the powder in the cartridges was replaced with a high explosive powder that would generate five times the pressure in the firearm.

The high explosive powder inside the cartridges would typically cause the AK-47 receiver to explode sending bolts and pieces of the gun backwards towards the person holding the rifle.

Once the sabotaged ammo was ready to go, U.S. forces would return the ammo to the stashes and would usually put one bad round in a container full of good rounds.

Basically, this would put doubt into the enemy’s mind regarding the safety and reliability of their ammo.

In addition, most of the Communist forces ammo was coming from China so this also was done so the enemy would question the ammo they were receiving from China.

The fact is, our firearms are obviously worthless without ammunition that works.

I’m sure you’ve heard how many gun activists want to make ammo harder to come by and there is no question that depending on where you live, it’s becoming more difficult to walk into your sporting goods store to buy ammo.

This has led to a continuing growing popularity of reloading your own ammo. Now, I know people who have done this for years and are very good at what they do.

On the other hand, I have a family member who spent countless hours reloading thousands of rounds, only to find out the powder was a little off and the ammo was unusable.

This is why if you reload ammo you have to take your time and know what you’re doing. This is not something you want to watch one YouTube video about and then think you’re a pro who knows it all.

So, if you are considering getting into reloading ammo, keep in mind the factors below and make sure you invest the time to do it right.

Reliability.
As I mentioned, I had a family member who reloaded his own ammo and was slightly off with his measurements.

Of course, no one is perfect, but the thing is, the big ammo manufacturers clearly have numerous safety inspections in place that make their ammo much more dependable, which is why quality ammo rarely has any issues.

Cartridge gets weaker.
Unless you keep your eye on every cartridge you use for reloading, you never know how many times the cartridge has been reloaded. The more you reload a cartridge, the weaker it will become over time.

Essentially, as it becomes weaker, it will be more prone to failure and malfunctions.

Legality.
I realize this is a big “what if,” however, if you were ever involved in a self-defense shooting would you really want to explain your reloaded ammo?

Again, I realize this is a stretch, but it is one more thing an aggressive prosecutor or civil attorney could use to try and blame you for what happen. During a trial, the best thing you can do is show the court a box of ammo from the manufacturer and say contact them with any questions.

When it comes to ammo, some of my favorite brands are Speer, Hornady, Remington, Winchester, and Federal. These are all quality and dependable brands that won’t break the bank.

I do realize a lot of folks reload ammo for the huge savings cost. If this is the case, I see nothing wrong with reloading rounds for simply target practice at the range or shooting with friends.

However, I would not use reloaded rounds in my self-defense weapon and I would spend the extra money to make sure you have a reliable round when your life depends on it.

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.

New cases? Decisions you make before that first firing have a lot to do with future success. Read why (and how) HERE

Glen Zediker

case segregate
I segregate my new cases before firing because I need to know which are for which. Do not first-fire cases using a lighter (less pressure) load unless you intend to continue to use that load in those cases for subsequent firings! I’ll use “old” 300- and 600-yard cases for offhand practice, but never the other way around!

The past few articles I’ve been begging indulgence from all the bolt-gunners out there by focusing on a few semi-auto-based topics, and so this time I’ll get to something of more interest to them (and it’s also of interest to “all of us”). In practical terms, which is living with reloads, it is at least of as much interest, or at least importance, to someone running an AR15 (if they’re looking to get maximum on-target performance from it). Subsequent case life has a lot to do with how you go about firing that first time.

So: definition: “Fire-forming” is a term usually associated with describing changing a cartridge from its original or “parent” state into another state, which is a non-standard cartridge, when it’s first-fired in the non-standard chamber. Like making an Ackley-Improved version of a standard cartridge, or converting a .250 Savage into a 6XC. In other words, the firing itself expands and reforms the case to the shape of the new chamber, and the case that emerges is then the new cartridge.

But! All cases are fire-formed to the chamber they’re first-fired in.

Details: Brass alloy is both plastic and elastic. That’s the “technical” reason changes in a fired case can and does occur in the first place. Plastic means that brass can expand and flow to fit the chamber, and retain its new shape. Elastic means that it doesn’t fully and completely mold itself to become a new mirror of the chamber. It “snaps back,” retracts from its maximum expanded form. If it didn’t it wouldn’t want to come back out of the chamber. That “snap-back” amount is predictably 0.001 inches.

case mushroom
Here’s a good example of the plastic property of brass alloy. This is a .250 Savage case that’s been run through a 6XC sizing die. Next step is to load it up and fire it in the 6XC chamber. It comes back out looking just fine! By the way, the little dings and creases we see in spent cases sometimes are really nothing to worry about: they’ll iron out after firing again.

On any rifle with a “standard”-dimension chamber, a new brass cartridge case will be smaller than the chamber. Has to be. It wouldn’t fit if it weren’t. A “standard” chamber, here, means there may and likely will be small variations from chamber to chamber (reamers vary uniquely, as might the operator’s preferences and judgment regarding how “tight” the headspace will be), but nothing intentionally has been done differently to alter the chamber beyond SAAMI-spec dimensional tolerances. Anyone who has loaded for the same cartridge for more than one rifle, and who has recorded pre- and post-fired case dimensions, knows that it’s common for there to be at least a thousandth or two, or more, variance. That’s all fine, as long as it’s within spec. Some custom-done barrels might have a chamber that’s intentionally different than SAAMI blueprints, and that’s a whole different topic.

Back to it: Since the brand-new cartridge case is smaller than the chamber it’s going into, it’s going to expand, grow. That’s clear.

ppc tallboy
Here’s a .22 PPC (left) next to a wildcat version, the “Tallboy.” There’s a whopping lot of permanent stretch to make this round (which is the precursor to 6.5 Grendel by the way). It is really important that this initial firing be done with a stout propellant charge. They would, not may, fail if the first firing didn’t fully expand the shorter PPC case.

So, there are two “forms” fire-forming can take. As said, no matter what else, all cases are formed to the chamber on their first firing. However, for some there can be some benefit from approaching that initial firing following a method or means to establish the set-in behavior of that case on subsequent firings and reloadings.

Here’s why some planning and procedure matters: Brass alloy has a “memory.” This is, more technically, called a “shape-memory effect,” and is shared by some other alloys also. It expands (and contracts) in a consistent pattern each use.

The first firing establishes that pattern. On subsequent firings, less is okay, but more is not. Lemmeesplain: I strongly recommend first-firing with a stout load, or at the least the stoutest load you plan on running through that case in future uses. When I segregate my new cases, I’m sorting them based on their function for me. My best go to the “600-yard” pile, then to 300 and then to short-line. Those are three different loads. I need to know which cases are for which before I make the initial loading. Fire-forming with a lighter load and then using a nearer-to-max load in that same case will, not can, result in premature failures in that case. It doesn’t seem to matter much going the other direction. I would never charge up my 600-yard load in a case formed using my 200-yard load; there are significant pressure differences in those two.

If it’s necessary to reform through firing, making a new cartridge case, there are a few different methods I’ve seen used, but, what really matters is that the case fully forms to the new chamber. The usual influential changes occur in the case neck and shoulder, and also stretching fore and aft. The bigger the change the more important it is to fire initially with a full-power load. For maximum effect, it’s better to fire-form with something closer to a “max” load than something lighter. Brass gets harder each use, less pliable. Starting life as a new cartridge after that first firing, case life is longer, and better, if the case was fully formed.

dead length seating
For maximum subsequent case life, it’s important that, one, a case fully forms to the chamber. But! Two, also that needless stretching is avoided. To that end, first-firing with the bullet seated to touch the lands minimizes stretch. Reduce the load since this will, not may, raise pressure.

To aid that, a “trick” that helps a lot is to seat the bullet into the lands, firmly. The reason is because that already has the base of the case firmly seated against the bolt face. That prevents the primer strike from moving the case forward, resulting then in additional body stretching (beyond what already might be necessary). If it’s not the routine means used for bullet seating, this tactic requires a reduction in the load. When a bullet is moved from “just off” to “just on” the lands, pressure spikes at least equal to the value of 0.2-0.3 grains of propellant.

Guns and Taxes

David Hogg wants a federal tax on firearms and ammunition. Uh. David… That’s very old news! READ MORE

hogg

SOURCE: NRA-ILA

David Hogg has repeatedly broached the idea of taxing firearms and ammunition, including multiple times on Twitter, and only sometimes suggests a use for the tax revenue. Hogg’s tweets on a federal gun tax include references to implementing the same sort of licensing and permitting requirements as the government requires to drive a car or funding “gun violence” research.

We’ve previously addressed the problem with comparing “gun violence” and motor vehicle accidents or smoking, and the problem with anti-gun research, so we’ll focus exclusively on Hogg’s tax idea.

Except it isn’t Hogg’s idea. The idea of a tax on firearms and ammunition predates Hogg by about a hundred years. A moment on Google would have shown Mr. Hogg as much.

The Firearms and Ammunition Excise Tax (FAET) was first imposed in 1919. In 1937, the Pittman-Robertson Act directed all revenue from FAET and related excise taxes to be used for hunting-related activities. The FAET includes a 10% tax on the sale price of pistols and revolvers and 11% of the sale price of other firearms and ammunition, and 11% tax on archery equipment. The tax is applied whether or not the equipment is likely to be used for hunting. The U.S. Department of the Treasury Alcohol and Tobacco Tax and Trade Bureau provides an informative reference guide, and the Congressional Research Service compiled a report on the tax and relevant legislative proposals just this past March.

The Pittman-Robertson Act funds acquisition and improvement of wildlife habitat, introduction of wildlife into suitable habitat, research into wildlife problems, surveys and inventories of wildlife problems, acquisition and development of access facilities for public use, and hunter education programs, including construction and operation of public target ranges.

More than $12 billion has been collected under the Pittman-Robertson Act of 1937, including more than $761 million in fiscal year 2017 alone. Revenues from the tax are placed into the Wildlife Restoration Trust Fund and distributed to the states and U.S. territories.

The National Shooting Sports Foundation, the firearms industry trade association, put together an informative video about how the excise tax supports conservation efforts and an infographic showing how the money collected from under the Act has impacted species. Spoiler alert: the white-tailed deer population went from 500,000 in 1900 to 32 million today, and the waterfowl population grew from few to 44 million. There are similar success stories for other species, all made possible through the excise tax on firearms and ammunition.

The Firearms and Ammunition Excise Tax is public information, as is the distribution of funds. Awareness of the tax may be low, but that doesn’t make the tax any less real. More than three-quarters of a billion dollars was collected last year; such an amount does not go unnoticed, particularly by the state wildlife agencies that depend on that funding for research and conservation efforts.

Mr. Hogg and others who want a federal tax on firearms and ammunition, would be well-served by spending a bit of time researching an idea before they start issuing demands.

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.

RELOADERS CORNER: Beating The Fool Out of .223

Facebooktwittergoogle_pluspinterestyoutube

Hot topic! Zediker takes a look at 22 Nosler and .224 Valkyrie, two rounds that set out to maximize “sub-caliber” performance. READ ON

224 valkyrie and magazine
.224 Valkyrie seems poised to gain the most popularity, and for two good reasons: it’s more “available,” and it’s really, really good! Either of these new rounds needs a 6.8 SPC magazine due to the greater case body diameter.

Glen Zediker

Last time I nutshelled the history of the .223 Remington and suggested that round, and its 5.56mm NATO chambering in the “new” M16 was the start of the “sub-caliber uprising.” By that I mean in popularity ( Also as mentioned last time, there’s zero doubt that the motivation behind companies like Sierra developing better .224 caliber bullets came from military shooting team needs to use 5.56 in competition. We, pretty much, ended up with better bullets than the .223 Rem. could exploit.

Moving forward 55 years or so now two hot-rodded 22s seek to fully exploit the best of these bullets: 22 Nosler and .224 Valkyrie.

22 Nosler
What it is, is another way to stuff more into an AR15 upper and it’s impressive. 25-percent more case capacity compared to .223 Rem., which translates to solid +300 fps gains — close to a .22-.250. And anyone who doesn’t think .22-.250 is impressive is beyond me and mine. “Conversion” from a conventional .223 Rem. parts set takes a 6.8 SPC magazine and a new barrel with the new chambering, and you’re good to go. It’s a rebated rim so the case head stays at the .223-standard .378, and has same rim thickness, so no new bolt needed. It’s kind of a stretched and necked-down 6.8 SPC, and it’s the same overall case length as .223 Rem. The extra capacity comes from a .420 body diameter, supplemented also by its 30-degree shoulder. Unlike the other Nosler-brand cartridges which came off a .404 Jeffery, there’s no parent case for this one. Currently, brass has to come from Nosler. That’s a good thing. But it’s not cheap. Nosler makes great brass; it’s prepped and ready to load out of its box. It’s become my go-to brass for .223 Rem. when it matters.

nos vs 223
Way on back when I first started shooting an AR15 in Service Rifle competition I kicked back a question I had wayer on backer when I got my first AR15 broken in: Why didn’t they just make it .22-250? Well, in a way, they finally did! 22 Nosler is dang close to that legendary round in its performance. 22 Nos right, .223 Rem. left.

22 Nosler is an exciting thing, to me, because it’s a truly new cartridge that lets someone start off fresh with a SAAMI-standard-backed round that is significantly stouter than .223 Rem.

The variety of .224-caliber bullets make it flexible for all the uses a higher-speed round can be put to, including surely as a hunting cartridge, and, no doubt, as a paper puncher. As suggested, it’s pretty much a .22-.250. Even though I like the “shorter-fatter” direction in cartridges to optimize bullet seating architecture to optimize accuracy, 22 Nosler, for me, hasn’t shot one bit worse than .223 Rem., and dang sho leaves a more substantial contrail. Barrel life is going to be significantly shorter than .223 Rem. and it won’t be to the tune of the 25-percent increase in capacity relating to 25-percent shorter life; it’s more like 50-percent, at best. Trades. Maybe 3000 tops.

22 nosler, valkyrie, 223 compared
22 Nosler is faster than Valkyrie. By a fair amount, up to 100 feet per second, and easily a solid 50. I’m giving that from reputable manufacturer data. This chart is from Nolser. Speed matters, but it’s not everything for everyone. More about that next time.

.224 Valkyrie
About one year after the 22 Nosler, Federal countered with its proprietary creation. (These were each released at a SHOT Show.) At this brief moment in time, 2018, it’s the round that’s getting the biggest following amongst the higher-22-velocity seekers.

valkyrie versus nosler
Here’s what I (think) I think: If you’re wanting a simple switch and the most power the 22 Nosler is easy. The Valkyrie has better specs for the more serious target-precision-oriented, and a barrel in one will last at least a little bit longer. Valkyrie, left; 22 Nosler, right.

Valkyrie is based on the 6.8 SPC. It has a 1.600-inch case length, so is shorter than .223 Rem. or 22 Nosler. That’s good! It uses the same .422 bolt face as SPC, so that’s a needed part for a conversion. As with the Nos. it needs an SPC magazine.

Both the Nos. and the Valkyrie are well suited to handle the biggest of the .224 bullets, and, according to its maker, the Valkyrie was expressly intended to launch the 90-grain-range bullets. Given that, Valkyrie barrels tend to be 1-7 twist. That’s not “enough,” in my experience, and more about that soon enough.

So, which is better?

YES!

I like 22 Nosler. It gives the most speed. That’s pretty much the whole idea behind either one. There’s been some said about the ups and downs of the bolt face differences. The smaller .378 is a stronger bolt, but there’s more bolt thrust effect from the more powerful 22 Nosler, and that’s mostly on the case. I can’t see anything I’ve heard being a problem. I’ve not had issues. The Valkyrie case is shorter, and, as said, that is an advantage with longer bullets because the bullet doesn’t get seated as deeply into the case to end up at the same overall round length. That’s exactly in keeping with the “accuracy architecture” as was shown with the article on PPC.

22 nosler zediker
I bought into it enough that my “featured” rifle in my new book is a 22 Nosler, as is my “XL Carbine.” (As a matter of fact, half the project guns I built are NOT .223 Rem. Different cartridges can really re-purpose the utility of an AR-platform gun.)

Bottom-line, though, Valkyrie is an easier investment. Component prices (and availability options) are radically better. I think that for someone looking to explore the far end of the shooting range and ding some steel plates at 500 yards, the .224 Valkyrie would be my recommendation.

22 nolser components
Shopping seriously favors the Valkyrie! Nosler isn’t cheap. It’s also not cheap (outstanding quality). There, however, is a whopping price difference (right now) between the two respecting loaded ammo and cartridge cases.

But it’s not just nearly that simple! More about why, and more cartridges thrown in to add to the confusion, next time.
