Lee Precision APP Primer Pocket Swage Kit for Auto Processing Press

The Lee Precision APP Primer Pocket Swage Kit is a dedicated accessory for the Lee Automatic Processing Press (APP) that swages primer pockets while simultaneously removing the military crimp from brass cases. Swaging reshapes the primer pocket from the inside out, restoring proper dimensions so primers seat consistently during reloading.

Designed exclusively for use on the Lee APP press, this kit handles both large and small primer pockets on cases up to 2.5 inches in length, covering nearly all common rifle and pistol brass. It is an essential step for prepping military-surplus brass that carries a factory crimp, and it streamlines case preparation for high-volume reloaders.

The kit includes the swage push die, swage holder, push rod, small swage punch, large swage punch, and a shell holder adapter. The only changeover required between primer sizes is swapping the swage punch - no shell holder change is needed - making the process fast and efficient on the APP press.
