I shoot 45 colt boolits cast from wheelweight lead (454190 mold) powder coated & sized @255 gr round nose flat point…and stuffed on top of 8grains of Unique. Good accuracy on several rifles, and they give steel targets a WHUMP with authority! But please check powder and boolit recommendations from printed loading manuals. I do put a light crimp on ALL of my 45 Colt loads, in case I shoot them from a tubular magazine rifle.

Hope this helps.
