My Dad gave me roll of non lead Silveabrite 100 95.5 tin 4 copper0.5 silver to try casting a .32 cal for my flintlock.I was using a Lee mold and almost ruined it,the aluminum is too soft when trying to cut the spruce hole. you would have to cast it without the cutter then open the mold and trim.I have a steel .440 mold without a cutter so tried that it worked I have a hard 85 grain ball vs 130 grain lead ball.With a cloth patch it would work but man super light ball.
