Confusion about crimping...
I bought my lee 4 die set for .45 acp, which came with the factory crimp die. I see most people say they don't use this, but only under certain circumstances. This is what came in my kit, therefore, this is what I use. I have cast bullets on the way, but all I have loaded thus far have been plated bullets. Is there a change in method for crimping cast from plated because of the ridges in the slug? Thanks in advance for clearing this confusion!
