Hubbard, that may have been me discussing one of the two moulds I was testing back at that time. That mould never stopped casting wrinkled bullets from that one cavity. I tried everything I know to try. I used hot soapy water, alcohol, acetone, B-C Gun Scrubber, Brake Cleaner even a mild abrasive paste. I smoked the mould and also used the Midway Drop Out.
NOTHING and I do mean nothing fixed it. That one cavity in a two cavity mould just ain't gonna work. I no longer own it. I gave it away.
