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 $109.95 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.

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.”

Criterion Barrels Inc. (CBI) has a policy of rewarding excellence. As a way of supporting top shooters, Criterion will provide a new, free barrel to any shooter who sets or ties a national record when using a Criterion product. To explain, you get a new Criterion barrel for free if you set (or tie) a national shooting record using a Criterion barrel on your rifle.

Criterion Barrels hopes to increase awareness of its free barrel for record sectors program. Over the last few years a number of F-Class and vintage military competitors have benefited from this program, receiving a complimentary barrel of their choice after setting a new national record in their shooting discipline. Past record breaking shooters have included David Mark Honeycutt (with a 300-yard F-Class score of 600-50X), Samantha Huhtala (four records set in 600-yard F-TR competition), and Victor Betzold (M1 Carbine with a score of 375-6X).

Criterion may, in the future, create a rewards program for winners of national, regional, and local rifle matches. Potential earned rewards by match winners could include equipment sponsorships, barrel discounts, and free apparel items.

New .22 LR Rimfire Version of Classic M1 Carbine

Here’s a new product that would be a great starter rifle for kids and a perfect training rifle for CMP M1 Carbine matches. Legacy Sports recently announced their new Citadel M-1.22 rifle, a .22 LR rimfire clone of the legendary M1 Carbine (which was chambered in .30 Carbine, essentially a rimless version of the .32 Winchester Self-Loading cartridge). Size, weight, and balance of the Citadel M-1.22 are very similar to the real thing. Legacy’s new rendition is set up to shoot the popular, inexpensive .22 LR round. The new Citadel M-1.22 rifle is made in Italy by Chiappa Firearms (Armi Sport). The rimfire M-1.22 features a blow-back action, an 18″-long, 1:16″ twist barrel, fixed front sight and adjustable rear sight. It will come with 10-round magazines, in either a wood stock version at $391.00 (item #CIR22M1W) or synthetic stock version at $331.00 (item #CIR22M1S).

M-1.22 M-1 Rimfire Carbine Citadel

We think the M-1.22 will be a popular Christmas gift item and, as noted already, it is an ideal “cross-training” firearm for CMP Carbine Match competitors. Learn more about the new Citadel M-1.22 at the LegacySports website. In the near future, M-1.22 rifles can be purchased through GalleryofGuns.com.

CMP M1 Carbine Matches — Growing in Popularity
The CMP M1 Carbine Match is part of the CMP Games program that already includes Garand, Springfield and Vintage Military Rifle Matches. “As-issued” U. S. Military M1 Carbines are fired over a 45-shot course of fire at 100 yards on either the old military “A” target (or the SR target, if A targets prove to be too difficult to obtain). The course includes 5 sighters and 10 shots for record prone slow fire in 15 minutes, a 10-shot rapid fire prone series in 60 seconds, a 10-shot rapid fire sitting series in 60 seconds and 10 shots slow fire standing in 10 minutes. An M1 Carbine Match was fired during the National Matches in the early 1950s, and now is back. As a CMP Games event, it also can now be conducted as a CMP-sanctioned competition.
