Lee  Bulge Buster Kit and the appropriate Lee Factory Crimp Die (not included) 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. The Lee Carbide Factory Crimp Die must be  purchased separately.

** Will only work 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.

For use in  single station press or a turret press with the index rod  removed.

Glock  Cases: Lee Precision do 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 case back to its original thickness. If  this case is fired in a pistol with an unsupported chamber again, and this  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.
