I am about to start casting for my brothers Browning 1885, we plan to stay with 'Trapdoor loads', and within 100 yards. I have a Lee 400 grain mold and 'push thru sizer' coming. I have some aluminum pb checks for my 45 Colt that I hope will work? I am thinking about using a 2.5% tin, 2.5% antimony, and 95%? Am I headed the right direction?
Thanks, hc18flyer
