I just received one of these trapdoor hollow based moulds, and just made my first casts. The size is okay at about .460, but there's a raised lip on the base, as apparently the hollow base plug rises a little far into the first band leaving some room around the edges for lead. It's thicker than flashing. Is this common, I'm wondering, or intentional, or should I exchange it? Doesn't seem quite right. Seeing as how this is a copy of an original bullet, I figured I'd better ask.
