I had a few that were wrinkled. I read that wrinkling meant your mold was too cold. So I placed the mold over the pot for a few minutes and tossed the wrinkles back into the pot. After that they were popping out looking almost perfect.
After a while I had trouble getting the mold (2 cavity LEE) to close properly. I put a little wax on the bars and in the slots, after that it started working perfectly. I also lubed between the sprue plate and top of the mold with graphite (carpenters pencil). I never smoked the mold or used any kind of release. The bullets were dropping off real well, ever once and a while I get a hanger, not often.
Things went pretty smooth as long as I kept the pot between 725 and 800 F.
