Am about to start casting some 45 Long Colt boolits and looking for a recipe. I have a 452424 NOE 45 Long Colt mold with the pin to make it HP I got few years ago. With the pin, should be about 235 grains? I have a melting pot and a lot of ‘pure’ lead and most of the rest of the stuff but am not sure about the amount of tin and/or antimony to add in the mix. The point is if I shoot it, want it to mushroom - not bounce, and/or not lead up the barrel. Will running the boolits at about 850 - 900 fps with Unique. Any advice will be appreciated.
