I have made 10,000 9mm (135gr R.N.)castings without problems. My 6 cavity Policlips MX93 recently began leaving fins at the ogive end of almost every drop. I can slip a .008 shim between the mold halves. And there is a mild arc (Daylight) when held to a straight-edge. Parts are rare I think. So I'm seeking help from the FORUM. Anybody who has ever bent bronze molds , please tell me how. Or is that unwise?
Thanks.
