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.
