Lee Bulge Buster Kit and appropriate Lee Factory Crimp assures your mixed brass is bulge free. This push through die adapter will quickly remove the annoying bulge rings that shell holder constrained dies simply can't reach.

The Bulge Buster Kit includes:
Extension sleeve
Push through punch
Catch container and complete instructions

Works with these rimless cases: 380 ACP, 10mm, 40 S&W, 41 AE, 45 ACP, 45 GAP, and 45 Win Mag.

NOTE: 9mm cases are not able to be used in the Bulge Buster because it has a slightly tapered case and the rim is not completely flush with the case.
