I'm pretty new to this casting process, but I have successfully cast a number of Lee 356124-2R and 356120-TC along with 311160 boolits. I purchased and received a new 356-95RL mold this week and I've been struggling with getting a good cast from it. Three tries and pretty well struck out. I've cast probably 500 boolits and have less than a hundred that I'd say are pretty good. But none are really as good as some of the other two 9mm molds. Today I ran the temp from a start of 630F up to 730 and nothing really eliminated the wrinkles nor the 'nose' on the side of the boolit. Mold was both hot and cool and nothing worked. I use bottom pour Lee 20-4 with a PID installed. COWWs is the lead. I'm attaching several pictures. A couple of good 95s at the top, a batch of bad lower left which are typical of about 400 I've tossed back in and a group of the 124-2Rs that I just cast at about 670f without really trying this afternoon to make sure it just wasn't me. Several have small smiles you can see, but overall fairly decent.
What suggestions do you have? Go even higher on temp? I've had mold really hot and what I think is average and started off cold and nothing eliminates the problem.
Thanks for any help you can give me! John
