A few months ago, Forster Products released a limited run of a new prototype Primer Pocket Swaging Tool for the Co-Ax press. This is a metal shaft that attaches to the base of the press. After receiving very positive feedback from initial testers, Forster has determined to offer the product again, priced at $30.00 for a set of two (2) swage tools (for both small and large primer pockets).

Intial Testing Feedback on Forster’s Swaging Tool:
Several reloaders told us the tool required less force than expected and preferred using it over other swaging methods. Setup was straightforward, and overall performance removing military crimps from .223/5.56 brass was consistent and effective.

One customer ran over 270 cases through the tool across multiple headstamps and reported solid results removing 3- and 4-point crimps. Others noted that once properly adjusted, it did a clean job swaging primer pockets and allowed primers to seat properly afterward.

A few important observations also came through:

• Brass varies — even cases with the same headstamp can behave differently.
• Heavily crimped brass may require more care during operation.
• As with any swaging operation, excessive force can damage rims if the operator overpowers the case.

In other words — the tool works well, but like most case prep operations, proper setup and feel matter. Overall, Forster reports that user reports have been very positive given the good performance on real benches. Because of that response, Forster has made another limited quantity available.

If you process crimped military brass on your Co-Ax press and want to streamline primer pocket prep without adding another expensive, standalone tool to your bench, the new swaging tool for the Co-Ax is now available for $30.00. This include both small and large swaging units. CLICK HERE to order.

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 $119.99 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.

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.”
