Well I tried that bullet with 6 different powders & could only come up with a load that did 1†@ 50ft. I’m going to quit playing around with that mold & get another one to try. I think I’m going to try a RN bullet next; I’ve always had excellent luck with them in every caliber I’ve tried them in. It’s a shame because the 4 cavity 429360 mold cast a beautiful .431 bullets that filled out easily with crisp clean edges.
