APP Bulge Buster Kit (LEEPRODUCT)

The Lee App Bulge Buster Kit and the appropriate Lee Carbide Factory Crimp Die, restore free function of rimless cases that have low base bulges. Low base bulges usually occur from chambers that do not fully support the cartridge or cases resized in carbide dies from manufacturers other than Lee. These show a noticeable stop ring near the base. You will most likely find cases with these problems in mixed range brass. 

** Will only work with the following cases:  380 ACP, 10mm, 40 S&W, 41 AE (Use 40 S&W Factory Crimp Die), 45 ACP, 45 GAP, and 45 Win Mag.

The Lee Carbide Factory Crimp Die must be purchased separately. 

If your case is repaired by the bulge buster kit, do not shoot in firearms with unsupported chambers.

Use this kit with the LEE APP press product number 90933 or the Deluxe APP product number 91898
