The Frankford Arsenal Case Support Die builds upon the customized reloading experience provided by the X-10 Reloading Press. Designed by reloaders for reloaders, this reloading die easily threads into the X-10 tool head to add a swage step to your press. The standard 7/8”x14 threads makes the die compatible with other reloading presses that provide on-press swaging. Add a second case support die to your progressive setup for consistent depths when seating primers. Having multiple Frankford Arsenal support dies for all the calibers you reload makes switching between X-10 tool heads a simple process. Also compatible with presses that accept standard 7/8”x14 threads.
