lee .25-45 sharps dies

One of the challenges with picking up a “new” cartridge to reload is finding the right dies at the right price. .25-45 Sharps is becoming more popular with AR-15 shooter and reloaders, and the industry is responding with new products that give reloaders more options. One such example is the new .25-45 Sharps dies from LEE. This “Pacesetter” die set includes a full-length sizer/de-primer, a dead-length bullet seater, and a Factory Crimp Die- everything you need to form .25-45 Sharps brass and reload .25-45 Sharps ammunition for your AR-15. These dies are “Very Limited Production” – but I’ll note that Midsouth Shooters Supply has these dies for ~$35. and they are in stock as of today! That’s about 1/2 what other .25-45 Sharps die sets cost!

If you are curious about LEE rifle dies, I posted an in-depth write-up that covers pretty much every detail you can think of. I also posted the following in-depth write-up that covers .25-45 Sharps precision reloading from start to finish, a great resource if you are going to use these LEE dies to load .25-45 Sharps:

As noted in that article, I found once again when testing the LEE dies how critical it is to chamfer case mouths after forming brass as pictured here:

time to chamfer and debur!

The cartridges I loaded with the LEE dies turned out great, and of course I tested my sizing/forming die setup with my L.E. Wilson case gage to make sure dimensions were correct.

I can’t wait to shoot some of the ammunition loaded with these LEE Pacesetter .25-45 Sharps dies- I’ll keep you all posted with how they work out!

AR15 Gas System Enhancements, Part 2

Facebooktwittergoogle_pluspinterestyoutube

Reducing the influence of excessive AR15 gas system pressure is most directly done reducing the pressure itself. Here’s how!

Glen Zediker

This is the second of two articles on ways to tame down an “over-functioning” AR15 gas system. Aside from running more reliably, reducing the evil influence of an overly-rapidly unlocking system improves cartridge case condition, which means longer case life. The first article talked about ways to increase the time the bolt stays locked, or delay its unlocking, however you want to see it.

Going more directly to the “source,” there are also ways to reduce the actual amount of gas that gets to the bolt carrier key and that’s up now for this one.

Adjustable gas block
Here’s an adjustable gas manifold. It’s a way to restrict the flow of gases through the system. Don’t get too greedy! Make sure to err on the side of function. These are probably the single most effective means to tame over-function. Check this one out HERE.

An adjustable gas manifold or “gas block” is an effective means to restrict the amount of gas that gets into the system. This device attaches at the port location, replacing the existing manifold (or front sight base if it’s a standard-configuration build) and will have some manner of valving function whereby propellant gases allowed to pass through the gas port in the barrel, through the manifold, and into and through the gas tube are restricted. Some incorporate a valve that regulates the passage dimension. Others provide a vent, more or less, to expel excess gas. I prefer the “valve-type” over the “bleed-off-style” devices.

Installation is straightforward, and these are available from a wide array of sources, so it shouldn’t be hard to find one that will fit even a custom-profile barrel. Standard for this area is 0.750-inches diameter. What matters is that the inside diameter of the manifold matches the outside diameter of the barrel at the connecting position.

There are different approaches to using this device but it’s really pretty simple. Figure out the minimum gas flow necessary to function the action and then open the flow-control screw adjustment a half turn more to give a little safety margin. Don’t get greedy. I shut one down all the way (minimum flow) and then open it up until the rifle functions.

The only foible on an adjustable manifold is that it has to fit in with the architecture of the setup you have. A retro-fit requires removing any muzzle device that might be installed and, of course, removing and later reinstalling the gas tube (make sure you check that it isn’t binding).

I have used other products that provide alternate means to do the same thing, like a gas tube with a valved adjustment mechanism. Sometimes something like that is best for anyone wanting to run a more standard gas manifold system. They work just fine, and dandy.

adjustable gas tube
There are other means for softening the system, and this adjustable gas tube is an example. Others include the “pig-tail” gas tubes that spiral around the barrel to increase tube length/volume. They all work…

Other gas tube modifications that work have been those formed in a spiral that wraps around the barrel, and I’ve seen tubes with expansion chambers (area of larger volume) along the span of the tube. What’s happening with these isn’t reducing the amount of gas, it’s just giving it more distance or room to weaken its presence.

The best solution I’ve yet encountered is fairly new and is an adjustable bolt carrier key. This requires no modification or labor about the barrel, and also works with virtually any AR15. Remove the old carrier key and replace it with the adjustable key.

adjustable carrier key
Here’s fairly new: an adjustable bolt carrier key from Sun Devil. David Beatty hit a long ball with this device, the ADIGS. I like it because it can be added to virtually any AR15 out there, even one that needs to maintain outwardly stock appearance. Works great. See more HERE.

A good while back I talked about gas port pressure and propellant burning rates and cautioned against using a propellant on the slower-burning side of “suitable propellant chart” center. To reiterate, I don’t think any propellant faster than Hodgdon 4895 should be used, but I know full well I can safely extend that range one more step to say something like Varget or RE15 is the limit. Slower propellants create more gas port pressure because they peak farther down the barrel, nearer the gas port location. Related: I recommend to anyone who’s going to do a longer custom barrel to request that the builder relocate the gas port another inch forward. There’s more gas contained in a longer barrel for a longer time: more pressure hits the carrier key as a result.

long gas tube
It’s common for an NRA High Power Rifle to get its gas port relocated forward another inch, or even two. The reason is because the 24-inch+ barrels we run “trap” more gas inside, which increases the pressure available at the gas port. The port farther forward gives more time and room (all the gas goes out when the bullet exits the muzzle).

No doubt, if you load up an AR15 with a heavy carrier and related parts then combine that with a gas restriction device, the range of propellants can move one or more steps slower-burning. In any of my full-blown across-the-course race guns, I can construct and successfully deploy loads that would wreck a rack-grade AR15. Don’t mess with that. Enjoy smoother and “softer” function and the assurance that you can run closer to a maximum load without fear of the odd and inevitable “pressure spike” causing problems. That’s why to do it.

Reloaders Corner: AR15 Gas System Enhancements, Part 1

Facebooktwittergoogle_pluspinterestyoutube

AR15s can have problems “over-functioning.” There are two essential ways to make your AR15 behave better! Here’s the first…

Glen Zediker

Right. I know this column is about handloading and reloading, so why am I spending space talking about gas system function? Well, it’s ammunition-related, or, at the least it is influenced by ammunition, and therefore also influences ammunition choices.

First, an AR15 gas system “over-functions” when it fills up too quickly and with too much burned propellant gas. The AR15 uses a “direct impingement” gas system, sometimes called an impulse system, and that means there’s a port hole in the barrel that lets gas out and through a gas tube, and this gas goes directly into the bolt carrier key and sends the whole works backwards. There’s no piston (although piston systems exist that can be fitted to these firearms) or other regulating device beyond gas port hole location and size.

AR15 bolt carriers
An M-16-profile carrier (back photo) weighs about 1 ounce more. Big big difference in slowing down initial movement. Get the right firing pin! If it’s a full-diameter carrier it will have a shrouded firing pin recess and takes a “large-collar” pin for correct operation.

The effect or upshot of over-function is overly quick bolt unlocking. The symptoms include extraction problems, damaged case rims (related), overly-blown cartridge case shoulders, excessive case head expansion, and, generally, accelerated wear on the action hisseff. As with many things, the severity of the excess function likewise increases excess in its manifestations.

What happens is that the case is swelled up under pressure inside the chamber, as it should be, but then it’s still swelled up when the bolt opens and the extractor takes a yank on the case rim to get it out of the chamber.

With respect to handloading ammunition, keeping the bolt in battery a tick longer makes a world of difference in spent case condition. The case has a tick more time to return to closer to normal dimensions and shrink away from the chamber walls. And time is, again, what this is really about. The case will be less stressed and dimensionally nearer original specs, and that means there’s “less” sizing done for next use, in effect. Case life improves and also does longer-term quality for reuse.

So. If we can delay bolt unlocking we’re seriously on to something. The simplest way to slow something down is make it heavier. Heavier things don’t accelerate as fast, they have a greater “moment of inertia,” less resistant to initial movement. Increasing bolt carrier mass is very effective. Keep in mind that what unlocks the bolt isn’t bolt movement, it’s bolt carrier movement. The bolt movement is a natural oucome to rearward travel of the carrier. Minor point but, well, there it is. I run “M-16 style” bolt carriers in all my AR15s. That’s a carrier with a full round section at the end rather than the notched out profile of the standard semi-auto carrier. And, no, an M-16 carrier won’t make a gun full-auto, and, as a matter of fact, carriers with the full-round profile are routinely encountered as “match” bolt carriers. Heavier is better!

Anything contacting the bolt carrier can increase in weight also and be effective. That effectively increases the load against the bolt carrier, and that requires more time to overcome and create movement. The buffer, for instance. I always run heavy buffers in my short guns, and also my hot-rod rifles for Across The Course use. The carbine-length stocks use a shorter spring and also a shorter buffer, and that means a lighter buffer.

AR15 buffers
Here’s an array of buffer components designed to slow the initial back-travel in the carrier. Anything helps, and more than one add-in makes an amazing difference in AR15 manners.

More about the spring’s role in all this next time, along with other more major modifications that will downright tame an AR15. And I’ll also run down a step-by-step on ensuring reliable function in a slowed-down AR15.

Reloaders Corner: Coated Bullets

Facebooktwittergoogle_pluspinterestyoutube

Bullet coatings promise better performance, but are they the right choice for you? Find out.


Glen Zediker


There are a few bullet coatings available, and Moly (MoS2: molybdenum-disulfide) is the best known, and also the most notorious. More in a bit.

moly coated bulets
Molybdenum Disulfide is the most popular bullet coating. It has exceedingly positive effects on performance, but there are may be some serious consequences for the uninformed user. Without correct (and frequent) cleaning, it can cause long-term damage to a barrel. Use it as outlined in this article and the extra speed and improved accuracy can pay back big to a serious shooter.

First, here’s how and why bullet coating works: Fire a coated bullet and a bare bullet using the same propellant charge. The coated bullet will go slower. However. The pressure will be lower. The reason is easy to figure: the increased lubrication reduces friction, resistance to movement, especially upon entry into the bore. It gets kind of a head start. The deal is that the pressure drops relatively more than the bullet speed, so, the bullet speed can be increased by adding more propellant and still have the same level of pressure. Win. Win. And, since there’s what amounts to a barrier between the bullet jacket and the barrel steel, the promise of more accurate rounds between cleanings is all true too. The bullet jacket isn’t leaving much of itself behind on the bore.

Among competitive shooters there was a huge shift toward coated bullets a few years back, but they’ve since fallen from favor for many. It wasn’t because they don’t perform well, because they do, but there are ancillary, and important, liabilities. Mostly: moly-coated bullets can corrode barrel steel, including stainless. Molybdenum disulfide outgases (outgas is the release of an occluded gas vapor that was part of the compound; a state change, pretty much) at temperatures lower than firing temperatures, and that creates a residue that, when mixed with water (moisture from condensation included, like what happens after firing), is pretty much sulfuric acid. Yikes. Right. If a moly-coated barrel is cleaned (correctly) each use, no problems. But one of the big draws is the potential to get literally hundreds of rounds, on zero, before the barrel needed cleaning. After a conventional cleaning (solvent and brush) it also takes time, which is rounds through the barrel, before zero will return.

I am a fan of coated bullets, and they’ve convincingly demonstrated their superiority to me after many thousands of rounds reaping rewards from the ballistic advantages. The improvement can be significant, and some bullets in particular escalate in performance more than others. Shorter bearing surface designs, by my notes, get that much more additional speed with no pressure trade-offs. Coating seems to have a disproportionately positive effect on thinner-skinned bullets, for reasons that likewise are clear. The effect here is smaller group sizes. Anything with a “J4” jacket responds well to coating (common in custom bullets).

My solution to the worries about moly was, as suggested, simply to clean the barrel each time back from the range and, also, to change my cleaning method to better accommodate the residue composition. More in a bit.

I don’t use moly any more, though. I’ve switched to Boron Nitride (BN) because it has all the advantages with none of the drawbacks, so far. BN is virtually the same in its effects as moly, based on my notes (same level of velocity drop and subsequent future increase). It’s easy to apply using a vibratory-style case cleaner.

BN coated bullet
This is a Boron-Nitride-coated bullet (right) compared to a bare bullet. BN is clear, slick, and doesn’t cause the chemical reactions other coatings are notorious for. It’s what I use.

I do not recommend any sort of lubrication inside a barrel, not for a promise of increased bullet performance. PFTE, for instance, has been touted as a great “break-in” agent for a barrel. Some use it after each cleaning to prep a barrel. Well. When it outgases, and it does outgas, it releases fluorine, a very powerful eater of all things metal.

Cleaning: Don’t use copper solvent with moly! The ingredients don’t mix well. Use only petroleum-based solvent. I switched to Kroil pentrating oil in conjuction with something like USP Bore Paste, JB Bore Compound, or similar (abrasive paste-type formulations). No room here now to convince anyone that abrasives are a safe and wise choice, but used correctly they are both. “Correctly” means a rod guide, stainless-steel rod, and keeping the rod shaft clean each pass. With that combination the bore is being protected against corrosion and the residues get gone, and, of huge importance, zero returns right away.

moly coated barrel cleaning
Bullet coating leaves an entirely different residue that conventional cleaners might not be effective on, and there’s also some chemistry involved that can inadvertently create big problems. I’ve had best results, all around, with a combination of micro-penetrating oil and abrasive paste. Keep the rod clean and feed it through a rod guide using abrasives and there’ll be no damage done.

Last on this: Just in the same as how I do not recommend “mixing” bullets or propellants through the same barrel, same day, coatings are pretty much the same. Zero will, not can, change for the number of rounds it takes to “re-season” the barrel. If you use it, use it.

I’ve seen great gaps in the quality of coated bullet finishes. Factory-coated bullets are the way to go. It’s tough to get a good job at home, and the reason is the carnuba wax application is temperature sensitive, and also because commercial coaters use industrial-level tumblers to apply the powder. The wax is necessary to avoid a smudgy mess just from handling the bullets. If you want to do it yourself, make sure the bullets are cleaned before application. Likewise, moly can build up in a bullet seating die so clean it out every now and again.

BN Coating Kit
BN can be applied easily using a vibratory tumbler and the contents shown. Put the BN powder in the bottle with the bullets, run the bottle in a vibratory cleaner for a spell, and that’s that. Check HERE for more information on bullet coating.

U.S. Law Shield News Update: Gun-Deregulation Ideas Offered by BATFE

Facebooktwittergoogle_pluspinterestyoutube

The news of the leaked white paper for the proposal to deregulate some rules from the ATF has been making it’s way around the web this week.

In an 11-page white paper labeled “not for public distribution,” but which has been obtained by Texas & U.S. Law Shield, Ronald B. Turk, associate deputy director and chief operating officer of the Bureau of Alcohol, Tobacco, Firearms and Explosives, outlines several steps the agency could take to remove many restrictions on gun regulations, including suppressors and stabilizing braces, in the United States. Texas Law Shield Independent Program Attorney Michele Byington walks U.S. Law Shield News Host Sam Malone through the proposals.

What are your thoughts on the deregulation of these accessories?

Ultimate Reloader: New 6.5 Creedmoor Ammunition from Norma

Facebooktwittergoogle_pluspinterestyoutube

Gavin Gear, Ultimate Reloader:

Norma is known for their high quality brass and ammunition, I’ve used Norma brass for precision reloading in calibers like .30-06 with great results. Recently, I saw that Norma had announced a new addition to their Professional Hunter lineup of ammunition: in 6.5 Creedmoor! I thought I should try some out with the Ruger Precision Rifle, and that’s what I’ll cover in this post.

As you saw in the video, this ammunition behaves more like match ammunition than it does hunting ammunition- I really wish it was deer season! Here’s the chronograph results:

With an SD of 13.7 FPS, this ammunition is very consistent in terms of velocity. It’s not surprising that the first four shots went into a .5″ group. This new ammunition is built around the Swift Scirocco II 6.5mm Bullet, and here’s more info about this precision-oriented hunting projectile:

Technical Information

  • Caliber: 264, 6.5mm
  • Bullet Diameter: 0.264
  • Bullet Weight: 130 Grains
  • Bullet Length: 1.350″
  • Bullet Style: Polymer Tip Spitzer Boat Tail
  • Bullet Coating: Non-Coated

Ballistics Information:

  • Sectional Density: .266
  • Ballistic Coefficient:.571

This is certainly a great choice of ammunition if you are hunting medium game with a rifle chambered in 6.5 Creedmoor. I do hope to show more 6.5 Creedmoor rifles here on Ultimate Reloader chambered in 6.5 Creedmoor- stay tuned!

It’s always good to feel the sharp recoil of the Ruger Precision Rifle against my shoulder, and to smell the burnt gunpowder in the air. Can’t wait to sit down again with this ammunition to see if I can get that 3/8″ 5-shot group I know this ammo is capable of! If you are looking for this new 6.5 Creedmoor Professional Hunter ammunition, Midsouth Shooters Supply has it!

Have you been shooting Norma Professional Hunter ammunition? If so, please share your experiences!

Thanks,
Gavin

Reloaders Corner: Outside Case Neck Turning

Facebooktwittergoogle_pluspinterestyoutube

For the perfectionist! Here’s a look at an often misunderstood and widely feared case-preparation step. It’s really not all that bad! Keep reading to learn what and why.


Glen D. Zediker


Outside cartridge case neck turning is a bench-top machine-shop-style operation. It is the only way to substantively improve case neck wall consistency. This is done via material removal using an outside case neck turning appliance. The outside neck turner shaves down the “high spots” around the neck circumference. That makes the neck walls more uniform in thickness. It’s a cutter and a gap, and that gap determines the case neck wall thickness. It’s finite.

neck turner
An outside neck turning tool, most of them, use a mandrel that’s inserted into the case neck. A cutting blade is then lowered onto the neck outside, adjusted for the amount (depth) of cut, and then is run around and around, going down the case neck a little each turn, shaving this amount of material from the surface. Like a carpenter’s plane. The slower you go the less the case neck will look like an LP.

It’s pretty well agreed on and accepted that concentric relationships mean better accuracy. Getting the bullet sitting dead center in a rifle bore means that the case neck must be “straight.” A “straight” case neck results from consistent neck wall thickness. And that’s because inconsistent wall thickness creates an off-center case neck cylinder when the bullet is seated. Consistent neck walls result in a center that’s concentric (if the tooling supports it).

This is a tedious ticky operation. If you are going to turn case necks, get what you think you are from it. The only tools I’ve used thus far that do a precise job of this op are the “hand-held” turners. The lower degree of tolerance is, as with many things, the reason. A tight fit between the mandrel that goes inside the case neck and the case neck inside diameter makes for a more precise operation. The mandrel and the cutter gap will be consistent and precisely adjustable; therefore, so too will be the resultant wall thickness. The first step is to size the case neck with an expanding mandrel to fit the mandrel on the turner. The higher-speed tools, such as those that operate under power or via a crank-style base rely on some other means to locate and fix the center of the case neck. That’s not to say better is not better, because it always is. Again, it’s degrees.

Use new brass!

I have a Gracey power turner that works so fast there no real reasons not to use it for every case. It, yes, without a doubt can make a case neck better. The Forster neck turning attachment that fits the Forster trimmer base unit (same used for case trimming, and other ops) fits the same description, as does the Horndady LNL tool. These are fast enough and easy enough, and the investment will improve wall thickness uniformity. Point is, if you want to turn each case neck you choose to 0.0095 inches, you’ll need a hand tool. And a micrometer. And time. With a hand tool, the job itself is not terribly difficult or slow, but adding in the initial neck sizing op and then another sizing afterward with the usual die, it’s steps.

Hornady LNL Neck Turner
As with many things, there’s a speed/quality tradeoff choosing an outside case neck turner. For my money, and time, I choose to go with a hand-held tool to get the most from the time I spend. I don’t turn all the cases, only the ones I’ve segregated into my “600-yard pile.” A good crank-style turner is the way to go for someone who wants to just run them all through. They’re faster but not usually as precise. This is a Hornady LNL Neck Turner, and it’s a great choice.

There’s a good question to answer and it involves the tolerance you’re willing to accept: perfection has a price. If the cutter head is adjusted to remove metal from the entire surface of the case neck, that means the wall thickness will be universally reduced. And that means you’ll now need to examine and possibly change your sizing setup to regain adequate post-sizing dimensions to secure a bullet. Using a routine sizer, the neck cylinder outside will get reduced to the same diameter as a case with thicker neck walls, but the case neck inside diameter will be larger because the walls are thinner. Depending on the expander diameter used in the die, the net result might be a case neck that retains an overly-large i.d. It’s just math. But make sure you work the numbers though.

Forster neck turning tool
To get the most precision from outside neck turning the case neck inside diameter must closely match the mandrel or pilot diameter on the neck turning tool. Lubrication helps! I use engine assembly lube gotten from a good auto parts store. Lube the case neck inside. You might have to adjust the sizing dimension to get this fit; some systems allow sizing with the same mandrel to get a close match. Cases should be sized and trimmed prior to the neck turning process, and then sized again afterward. Here’s a Forster hand-held tool.

I never aim to turn the full circumference surface area around a case neck. The reason is that means adjusting the tool to produce thinner than “blueprints.” The idea, for me, is to erase the inconsistencies that remain in my sorted brass: clean them up. For example, let’s say that, after measuring enough places on enough cases, I determine that a brass manufacturer intended this tubing to be 0.011 inches (that was the “blueprint”), that then defines the cutting depth limit I’ll set my turner to deliver.

If you do turn case necks, make sure to continue cutting a little ways down onto the case shoulder (if the cutter design allows this, it needs to have an angle incorporated for this purpose). This helps stay off the formation of a case neck donut. Works wonders.

partially turned case neck
Here’s how my cases look after neck turning. A little splotchy, but my goal is not a universal reduction of wall thickness, just “better is better.” So instead of a case being over 0.001 out of spec, now it’s about 0.0005 variation, but decidedly not perfect. Those with the smallest visible cut area were better from the start. I do this way mostly to preserve the sizing die dimensions and effect the same on all my brass. Thinner neck walls tend to crack easier, so it’s safe enough to say that, with a standard-type rifle chamber (not done with a “tight-necked” Benchrest-style reamer) case life will shorten. Notice the shoulder cut. Removing a little material from this area alleviates case neck donuts.
