    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 work with the following cases:  

    380 ACP
    40 S&W
    41 AE (Use 40 S&W Factory Crimp Die)
    45 ACP
    45 GAP
    45 Win Mag

    The Lee Carbide Factory Crimp Die must be purchased separately.
