How to Ream Military Primer Pocket Crimps with Wilson Tool

Military crimp primer pocket reamer

Many shooters, particular those who shoot vintage military rifle matches, reload once-fired military cartridge brass. This brass may be high-quality and stout, but you may encounter a primer crimp* that interferes with the seating of a new primer. There are a variety of dedicated, military-crimp tools on the market, such as Dillon’s excellent Super Swage 600 tool that “rolls the crimp away”. But the Dillon tool costs $114.99 and takes quite a bit of room on your reloading bench. If you don’t want to drop a C-note and give up valuable bench space — here’s another (much cheaper) solution.

If you already have a Wilson case trimmer set-up, you can ream away those military crimps using an affordable Wilson accessory — the Primer Pocket Reamer (large #PPR210, small #PPR175). This $32.65 accessory is used in conjunction with a Wilson case trimmer and case-holder as shown above.

Military crimp primer pocket reamerWilson

In the respected Riflemans Journal website, the Editor, “GS Arizona”, showed how to use the Wilson primer pocket reamer to remove military crimps on Lake City .30-06 cartridge brass. He explains: “The case goes into the Wilson case-holder, the same one used for case trimming, and the reamer replaces the trimmer head in the tool base. The threaded rod on the left side, which is normally used to regulate trim length has no use for this operation and it is simply backed out. Hold the case-holder as you turn the reamer into the primer pocket, it cuts easily and quickly. The reamer will stop cutting when the proper depth is reached.”

Do you really need to do this operation with military-crimped brass? Yes, and here’s why: “Any attempt to prime the case without removing the crimp will simply result in a mangled primer that cannot be expected to fire and certainly won’t fire reliably.”

Vintage Military Rifle shooters often utilize surplus military brass with primer pocket crimps.

*Why does military brass has a primer crimp? GS Arizona answers: “The crimp is nothing more than an intentional deformation of the case around the primer pocket, the purpose of which is to retain the primer in the case despite high pressure situations in machine guns and other automatic weapons where a loose primer may cause a malfunction. As reloaders, our task is to get rid of the remnants of the crimp in order to allow re-priming the case.”

Fact vs. Fiction — .223 Rem vs. 5.56x45mm NATO Cartridges

.223 Rem Remington 5.56 SAAMI CIP 5.56x45 5.56x45mm NATO cartridge ammo pressure test luckygunner ultimatereloader Gavin Gear

Probably the most popular centerfire rifle round in the Western Hemisphere is the .223 Remington and its metric match, the 5.56x45mm. Though many folks use “.223 Rem” and “5.56×45″ interchangeably, there are some meaningful differences in specifications for the original .223 Rem and the 5.56x45mm cartridge, as adopted by the U.S. military and NATO armies. The default chamber throats are slightly different and the .223 Rem is rated at 55,000 PSI vs. 62,366 PSI for the 5.56x45mm.*

.223 Rem vs 5.56x45mm — Key Differences
There is a truly outstanding, very thorough article on the subject, published by LuckyGunner.com.** This involved extensive testing, with pressure monitors, of 5.56x45mm ammo in .223 Rem chambers. Those tests revealed the peak pressures. Here is one of the ammo test charts:

.223 Rem Remington 5.56 SAAMI CIP 5.56x45 5.56x45mm NATO cartridge ammo pressure test luckygunner ultimatereloader Gavin Gear

NOTE: “The observed chamber pressure for Federal XM855 5.56mm ammunition in a .223 Rem chamber exceeded .223 maximum pressures, but not by a massive amount. The ninth shot (the red line) was an underpowered cartridge which exhibited significantly lower velocity and pressure than the other rounds, so it was excluded from the average velocity and pressure numbers for this chamber.”

And if you’re curious, LuckyGunner also fired .223 Rem ammo in a 5.56x45mm NATO-chambered AR15 rifle. As you would expect, the peak pressures were significantly lower, but the .223 Rem ammo still cycled the semi-auto AR-platform rifle perfectly well:

UltimateReloader.com Explains .223 Rem vs. 5.56x45mm
To explain the key differences between the .223 Rem and 5.56x45mm cartridges our friend Gavin Gear of UltimateReloader.com has created a very thorough 12-minute video. This covers the cartridge specifications and explains key considerations for hand-loaders. Gavin also addresses the oft-asked question “Can I shoot 5.56x45mm ammo in my .223 Rem chamber?” Gavin’s video is definitely worth watching. In fact, this is one of the most popular videos Gavin has ever created — it has been watched over 300,000 times on YouTube.

What Exactly Is the 5.56x45mm NATO Cartridge?
The 5.56×45mm NATO is a rimless bottle-necked intermediate cartridge family standardized by NATO with development work by FN Herstal. It consists of the SS109, SS110, and SS111 cartridges. Under STANAG 4172, it is a standard cartridge for NATO forces as well as many non-NATO countries.

Bullet diameter: 5.70 mm (0.224 in)
Maximum pressure (EPVAT): 430.00 MPa (62,366 psi)
Maximum pressure (SCATP 5.56): 380.00 MPa (55,114 psi)
Case length: 44.70 mm (1.760 in)
Rifling twist: 178 mm or 229 mm (1 in 7 in)
Parent case: .223 Remington (M193)

Ammo-Maker Federal Premium Compares .223 Rem and 5.56x45mm
Here is a video from ammo-maker Federal Premium explaining the difference between .223 Remington and 5.56x45mm NATO. Federal states that you may experience excessive pressures when firing a 5.56x45mm in a standard .223 Remington chamber:

One leading gunwriter has addressed the question of shooting 5.56x45mm ammo in .223 Rem chambers. He advocates caution (for more info, SEE pressure tests by LuckyGunner.com):

“I have received a slew of questions — many from first time AR-type rifle buyers — about the .223 Rem and the 5.56×45 mm NATO cartridges. Can I shoot 5.56×45 mm NATO in my .223 and vice-versa? Are these the same cartridge?

Externally, the two cartridge cases are identical. The main differences are that 5.56×45 mm NATO operates at a higher chamber pressure (about 60,000 PSI versus 55,000 PSI on the .223 Rem.) and the 5.56’s chamber is slightly larger than that of the .223 Rem. Also, the throat or leade is longer in the 5.56×45 mm chamber. What does this mean? You should not shoot 5.56×45 mm NATO out of a rifle that is chambered in .223 Rem. And be aware that some .223 Rem. ammunition will not reliably cycle through some AR-style .223 Rem. rifles, but it usually does. As a matter of fact, I have not encountered any difficulty with current .223 Rem. loads cycling through a 5.56 mm AR-style rifle.”
– Mark Keefe, Editor, American Rifleman


* According to the official NATO proofing guidelines, the 5.56×45mm NATO case can handle up to 430.0 MPa (62,366 psi) piezo service pressure. The U.S. SAAMI lists Maximum Average Pressure (MAP) for the .223 Remington cartridge as 55,000 psi (379.2 MPa) piezo pressure with deviation of up to 58,000 psi (399.9 MPa). The chamber for military 5.56×45mm NATO has a longer throat prior to the bullet contacting the rifling which results in lower pressures when firing 5.56×45mm NATO ammunition. If 5.56×45mm NATO is used in rifles chambered for .223 Remington the bullet will be engraving the rifling when chambered. which can increase pressures past SAAMI Max levels. NOTE: The C.I.P. standards for the C.I.P. civilian .223 Remington chamber are much closer to the military 5.56×45mm NATO chamber.

** The full-length LuckyGunner article is well worth reading. It even provides specifications for a number of .223 Rem reamer types, and compares the original .223 Rem, the 5.56x45mm NATO, and the modern .223 Wylde chamberings.

Uniforming Meplats — How to Point Bullets with Whidden System

whidden bullet pointing die system kit
Jason Baney photo from Whidden Bullet Pointing Die Review.

The new generation Berger LRHT Match bullets come with Meplat Reduction Technology™ (MRT) for more consistent BCs. Essentially they are “pointed” at the factory. Likewise, many of Sierra’s most popular MatchKing bullets are now factory-pointed in a final production stage. However, for most other bullet types, you can benefit from using a bullet pointing system to make the meplats more consistent.

Bullet pointing die system whidden

Gear Review by GS Arizona

This article originally appeared in the Rifleman’s Journal website.
Many of you have doubtlessly read Bryan Litz’s articles in our Daily Bulletin and on his Applied Ballistics website about various current long-range bullets. Bryan’s work carries a great deal of weight in the world of ballistics, so his comments (and mathematical proofs) regarding the benefits of bullet pointing certainly caught my attention. Bullet pointing, like meplat trimming, is an effort to reduce the ballistic inconsistency created by the somewhat jagged tip of the jacket where the bullet forming dies bring it to a point in the manufacturing process. Of course, we could eliminate this problem altogether by shooting closed-tip, open-base bullets like the Lapua D46, but that merely shifts the jacket problem to the other end of the bullet.

Whidden Bullet pointer tool

In any event, hollow point bullets rule the accuracy world today, so John Whidden, multi-time National Long Range Champion and a talented gunsmith to boot, came up with a very handy tool to let us make those hollow points pointier. Let’s have a look at John’s tool and see how it works.

Whidden Bullet pointer tool

The Whidden Bullet Pointing Die System uses a Forster bullet seating die body as its basic structure and that’s a good choice given the quality machining Forster does on these. The real heart of the tool comes in two parts: the caliber sleeve and the pointing die that fits inside the sleeve. In fact, to point up different caliber bullets, you only need to change the caliber sleeve, everything else remains the same. The last item is the bullet base that slips into a standard .308 shellholder and supports the bullet as it goes into the die body.

It took me less than five minutes to get everything set up, including changing the caliber sleeve from 6mm to .30 caliber. John’s instruction sheets are well illustrated and clearly written; you should have no problem getting up and running.

Pointing the bullets is as easy as sizing a piece of brass. You can see in the second photo above the difference between a few pointed bullets and a few un-pointed ones. The innermost pointed bullet in the picture was my first attempt and I adjusted the die a little after that, you can see that the others are closed a little more. John even includes a couple of sample bullets so that you can see one done right and one done wrong. That is a nice addition that can help you achieve the desired results.

This YouTube Video Shows the Whidden Bullet Pointing Die in Action

I think Bryan’s work supports the validity of this concept and John’s tool puts it into practice in a simple-to-use manner that makes it just about impossible to do any damage to the bullet. I have shot pointed bullets in various calibers at many matches now. Pointing is not a “miracle cure”, but I believe that pointing bullet tips can produce long-range accuracy gains, through reduced vertical dispersion, for many popular types of match bullets. The Whidden Bullet Pointing Die System retails for $220.00 (with one insert). Additional die inserts are $42.00 each. Extra caliber sleeves are also $42.00. You can purchase directly from Whidden Gunworks, or from Sinclair International.

Stuck Case Remover Kit — You’ll Need One Sooner or Later

Lyman Case Stuck Remover tool

Sooner or later, every hand-loader will get a cartridge case stuck in a die. Perhaps you forgot to lube a case, or maybe you even ran the wrong cartridge into the die. Thankfully, there are affordable solutions to the problem. Lyman offers a very handy Stuck Case Remover Kit. This compact Kit ($23.95 MSRP) contains ALL the tools you’ll need to remove most stuck rifle cases and pistol cases. (No separate tap holder is required.) Basically you drill and tap the stuck case, insert a cap screw, then use the wrench to remove the case from the die through a camming action. The Lyman kit, part #7680350, includes a unique, dual-purpose threaded cap that screws over the end of the die. This cap acts as both a drill guide and a guide for the pulling screw. An extra-long hex wrench is included which provides plenty of leverage when removing stuck cases and also doubles as a handle for the tap wrench.

How Stuck Case Removers Work — Video Shows Process
The new Lyman Kit isn’t the first stuck case remover device on the market. RCBS also offers a Stuck Case Remover Kit that costs just $16.14 on Amazon.com. The RCBS unit works fine, but you will need a separate tool handle to hold the tap. This video shows how to remove stuck cases with the RCBS tool. The operation is similar with the new Lyman tool.

Hodgdon Powder Availability — Q&A about Supply in 2020

hodgdon powder extreme Varget H4360 shortage supply Q&A

Many of Hodgdon’s most popular powders, such as Varget and H4350, have become very hard to find. Shipments sell out as soon as they reach retailers’ shelves. We know our readers and Forum members are concerned about these supply shortages. Why are these powders in such short supply, and what is the prospect for more Varget, H4350, and other Hodgdon powders in the months ahead?

Hodgdon answered these (and other) questions recently in a Q&A post on the Hodgdon Facebook Page. Here are highlights of those Questions and Answers.

HODGDON POWDER UPDATE Frequently Asked Questions

Here are answers to your questions straight from Hodgdon, 1/31/2020:

Q: Why can’t I find Hodgdon powders like H4350, Varget, Retumbo, and H1000?

As you have seen, Hodgdon powders, especially rifle powders for long-range and precision shooting, can be difficult to find. Dealer shelves that were formerly filled with cans of powder now have empty spots. [Hodgdon added: “Dealer shelves are empty because powder is purchased as soon as it arrives at the dealers’ stores.”]

Q: Is Hodgdon still making powder?

A: Yes, we continue shipping powder as quickly as possible. In fact, we will ship more powder in 2020 than last year. The real problem behind empty dealer shelves is complicated, but is related to shifting supply and demand challenges. As supply decreased in 2019, demand only increased. No one wants to ship more powder than Hodgdon.

Q: What is causing the supply challenges?

A: Quite simply, our manufacturing facilities have not kept up with our orders. Additionally, military contracts began specifying Hodgdon powders in the last few years for military ammunition, impacting our supply. With expanded government regulation, shipping explosive and energetic materials has become more challenging, which also impacts available supply. Lastly, rapidly changing consumer preferences for different powder types has impacted both demand and supply. We worked with all Hodgdon providers to resolve open issues and expect powder supply to improve in 2020 as a result.

Varget, H4350, H4831SC, and other ‘Extreme Series’ powders are in very high demand.
hodgdon powder extreme Varget H4360 shortage supply Q&A

Q: Is the shortage of reloading powder being caused by Hodgdon shipping their powder to the ammunition manufacturing companies?

A: While Hodgdon does sell powder to ammunition manufacturing companies, more than 80% of our powder is sold to our core market – handloaders just like you. Hodgdon has always been committed to the individual handloader.

Q: When will I start to see more powder on dealer shelves?

A: While Hodgdon will continue to ship powder as rapidly as possible, we have a significant backlog in demand. Some powders will be in stock more quickly, but we believe it will take much of 2020 to improve availability for all powders. [Editor: In a separate post, Hodgdon stated “We will be sending out large amounts of H4350 starting mid-March.”]

What Is Better — Weighed Powder Charge or Volumetric Charge?

Lee Auto-Disk Chargemaster weight vs. Volume

When we first ran this story a while back, it spurred a hot debate, with strong opinions on both sides of the issue. Some guys argued vehemently that volumetric powder dispensing was best — citing the experience of short-range benchresters, most of whom still throw their charges. Others say weighing your charges is best, so long as you have a very precise, and very repeatable scale. Many of the top F-Class and 1000-yard shooters now weigh their charges to the kernel.

Lee Auto-Disk Chargemaster weight vs. VolumeMost competitive long-range shooters weigh powder charges for their handloads. Some even use ultra-precise magnetic force restoration scales to load to single-kernel tolerances. But is weight-based measuring always the best way to fill a case with powder? Another option is volumetric charging. This method fills a precisely-sized cavity with powder and then dumps the charge into the case. A Harrell’s rotary powder measure works this way, as does the sliding powder filler on a Dillon progressive press.

For long-range applications, most people believe that precise weighing of powder charges is the best way to achieve optimal accuracy and low ES/SD. However, those short-range Benchrest guys do pretty darn well with their thrown charges, at least at 100 and 200 yards.

Our friend Dennis Santiago recently observed something that made him scratch his head and wonder about weighing charges. His AR-15 match rifle shot better with volumetric (cavity-measured) charges than with weighed charges dispensed by an RCBS ChargeMaster. Here’s what he reports:

Cavity vs. Dribble (Dennis Santiago Report)
I had the chance to compare nominally identical ammunition loaded two ways. These were all .223 Remington match loads using 77gr Sierra Match Kings over 23.4 grains of Hodgdon Varget. Same gun. However I loaded some ammo with charges dispensed with a Lee cavity-style powder measure while other rounds were loaded with powder weighed/dispensed by an RCBS ChargeMaster. The cavity-drop ammo (with powder dropped from the Lee unit) was consistently better than the weighed-charge ammo. I have no idea why…

So, ladies and gentlemen — what do you think? Why did Mr. Santiago’s volumetrically-charged ammo shoot better than ammo filled with weighed charges? What’s your theory? Gary Eliseo suspects that Dennis’s Chargemaster might have been drifting. What do you think? Post your theories in the comments area below.

The 6mm-223 — A Wildcat Worth Considering

6mm 223 sinclair

Intro: Ron Dague wanted a new gun that was similar to his trusty .223 Rem rifle, but which fired 6mm bullets. There is a superb choice of bullets in this caliber, and Ron found that the 95gr Berger VLD could be driven to a healthy 2,604 fps by the small .223 Rem case. This 6mm wildcat based on the common .223 Rem offers excellent accuracy and very low recoil — something very important in the cross-the-course discipline. In addition, Ron’s 95gr load with Reloder 15 delivered an ES of just 4 fps over ten shots. That exceptionally low ES helps achieve minimal vertical dispersion at 600 yards.

6mm 223 Across the course McMilland stock Ron Dague Sinclair InternationalBy Ron Dague, Sinclair Reloading Tech
From Sinclair’s GunTech Articles Archive

I already had a .223 Remington match rifle, and I wanted the 6mm-223 to be as close to the same as I could make it. I installed the barreled action in a wood 40X stock to work up load data and work out any magazine feeding issues. While I was working on that, I looked for a McMillan Baker Special stock and finally found one to finish this project. I bedded the action and stock, then took the rifle to the range to check zeros on the sights and scope. I was surprised that I didn’t have to change anything on the sights. I thought changing the stock would cause sight changes. The thought went through my head, “Maybe the 40X stock isn’t all that bad”.

Here’s line-up of 6mm bullets. The Berger 95gr VLD is in the middle.
berger 6mm bullet hornady sierra line up 6mm 233

I took the new rifle to the first match of the year, a National Match Course match, and my off-hand score was 83, rapid sitting 95, rapid prone 95, and slow fire prone 197 — for total aggregate 470. This may not be my best work, but on match day the wind was blowing about 15 mph and the temp was around 40° F, with rain threatening. This was a reduced course of fire — we shot at 200 and 300 yards on reduced targets.

I used 70gr Berger bullets for this match, loaded in Remington brass with 25 grains of VihtaVuori N540 and Federal 205M primers. When I worked up loads for this rifle, N540 gave the best accuracy with the best extreme spread — 2,950 fps with an extreme spread of 20 fps on a 10-shot string. The load for 600 yards was with a 95gr Berger VLD bullet, with 23.0 grains of Reloder 15, Lapua cases, and the same Federal 205M primers. This load is 2,604 fps, with an extreme spread of 4 fps over a 10-shot string. I’ve shot this load at several 3×600 yard matches, and the accuracy has proven to be very good. At the last 3×600 match, my scores were as follows: 199-10x and 198-11X with scope, and 193-10X with iron sights. Best 600-yard score so far with iron sights was 198-12X.
