The Lee Automatic Processing Press (APP) Bulge Buster Kit and the appropriate Lee Carbide Factory Crimp Die restores free function of rimless cases that have low base bulges. Low b ase 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. The Lee Carbide Factory Crimp Die must be purchased separately. Note: Works 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. Show more
