So two weeks ago I bought a Lee Bulge Buster "kit." Today while I was at Graf's I purchased the Lee 4-die carbide set. Took it home and immediately attempted to bust the bulges that might have been in any of the empty cases I already had. In my hurried rush I forgot to fully read the instruction sheet again. I left the steel crimp sleeve in the die and attempted to bust the bulges. Upon the second casing I noticed a severe impediment to my work. The first case was stuck in the crimp sleeve. The bulge buster works great when you remove the part that doesn't belong. Now I have two options: 1) figure out how to unstick the case 2) buy another factory crimp die.
