I ordered a Hardline 9mm RN mold, 115gr, I ordered it for using Coatings, I'm having problems casting with it, Bullets always come out wrinkled, I tried adding more tin, NG. Higher heat bullet starts showing frosted but still wrinkled. I also tried casting faster. Occasionally, it will drop good bullets, then it goes back to the wrinkled. I tried it again yesterday, first scrubbed the hell out of it using brake clean then blowing it dry, cast over 100 and not a good one, WHAT AM I doing wrong. Yesterday switched over to my RCBS 9mm and after a few bad ones, I started getting perfect bullets.
