Lee: Producing High-Quality Reloading Equipment
The Lee App Bulge Buster Kit, used with the Lee Carbide Factory Crimp Die, allows rimless cases with low base bulges to reclaim their free function. Chambers that do not fully support the cartridge or cases resized in carbide dies from manufacturers other than Lee are the most common causes of low base bulges. There is a visible stop ring near the base of these. Cases with these issues are most likely to be found in mixed range brass.
Will work with the following cases:
41 AE (Use 40 S&W Factory Crimp Die)
45 Win Mag
