I have all LEE molds .501 440 gr. , .457 405 gr. .452 300 gr., .430 310 gr. All gas checked except for the .457 all wide nose flat point. My lead is around 15 BNH . I am only using this lead on 45 colt,44 mag and maybe 454 casull. My next batch I will need to bring up my BNH for other calibers like 444 marlin,45-70,450 marlin, 460 and 500 s&w.
