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 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: We 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.
