Lee Precision Automatic Processing Press (App) Primer Pocket Swage Kit
$45.00
The Lee Precision Automatic Processing Press (APP) Primer Pocket Swage Kit is a complete solution for shooters who want to recondition military brass with crimped primer pockets. If you reload rifle ammunition and work with once-fired military cases—or buy bulk brass that's been through military specifications—this kit removes those stubborn primer crimps and simultaneously swages the pocket smooth, leaving a clean, uniform seat for fresh primers every time.
Reloading precision starts with case prep, and a properly prepared primer pocket is non-negotiable for consistent ignition and safety. Military-crimped pockets can cause seating issues, primer smearing, and unpredictable variability downrange. This kit handles both the decapping (removing the crimp) and swaging (resizing and smoothing the pocket geometry) in a purpose-built process designed specifically for the Lee APP press. It's the kind of tool that transforms a pile of salvaged brass into ammunition you can trust.
The kit ships with everything you need for both .22 and .30 caliber applications, including matched decap and flare dies, the swage push die, swage holder, caliber-specific push rods, and both small and large swage punches. You'll need a universal or X-PRESS shell holder to run the kit—if you're using a Deluxe APP press, your unit arrives with shell holders #2, 4, and 19 already included. This is a Lee APP–only tool, so verify your press model before purchasing.
Whether you're a volume loader stretching your ammo budget or a precision rifle shooter who demands perfect case preparation, primer pocket conditioning separates good reloads from great ones. This kit puts that level of control in your hands.

Frequently Asked Questions
What's included in this kit, and what do I still need?
The kit includes decap and flare dies for both .22 and .30 caliber, the swage push die, swage holder, push rods for each caliber, and both small and large swage punches. You'll need a universal or X-PRESS shell holder to operate the kit—these are not included with the standard kit. If you own a Deluxe APP press, shell holders #2, 4, and 19 ship with your press.
Can I use this on my single-stage or turret press?
No. This kit is designed for the Lee APP press only and will not function on other press types.
Why do I need to swage primer pockets on military brass?
Military ammunition is produced with crimped primer pockets to prevent primers from backing out under firing pressure in automated military weapons. When reloading that brass, the crimp interferes with new primer seating and creates an uneven pocket. Swaging removes the crimp and reshapes the pocket to a smooth, uniform geometry, ensuring reliable primer seating and consistent ignition in your reloads.
Does this kit work for both .22 and .30 caliber ammunition?
Yes. The kit includes caliber-specific decap/flare dies and push rods for both .22 and .30 caliber applications, making it versatile across those two calibers.
