Lee Bulge Buster Kit and the appropriate Lee Factory Crimp Die 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 Complete Instructions Works with these rimless cases: 380 ACP, 10mm, 40 S&W, 41 AE, 45 ACP, 45 GAP and 45 Winchester Mag. It does not work with 9mm cases, because the rim is not completely flush with the case. Lee also does not recommend "fixing" cases fired in pistols with unsupported chambers, because there is no way to make them safe once they have bulged. The case wall is thinned where it bulges, and resizing the outside of the case back down to the correct diameter does not restore the back to its original thickness. If this case is fired in a pistol with an unsupported chamber again, and the thinned section of brass happens to line up with the unsupported part of the chamber, there is a high probability that the case will rupture. Lee reloading equipment is the best value on the market today. Lee Dies are standard 7/8 by 14 thread and fit all the modern presses such as; Dillon, Hornady, Lee, Lyman, and RCBS.
