I have been reloading for years and gradually moved from jacketed to cast loads. I JUST started casting my own and started with some 45 ACP tumble lube in a Lee mold which went very well. The next time I tried using a 200 gr .44 "regular lube" (non-tumble) mold and I had trouble after casting roughly 100 perfect .44's; the bullets started sticking in the two cavity, well smoked mold. What am I doing wrong?
P.S. Using 50/50 mix of Linotype and pure lead to get something like 2%-6%-92% mix.
