    Lead/tin may work for revolver, I just shoot semis and pure/2-3% Sb works fine, no tin. 40sw & 9mm. I use pure with roto superhard for Sb. Get the alloy calc for weights required.
    Whatever!

    My experience has been that for standard handgun loads an alloy with 1-2% tin and 3-5% antimony will produce bullets hard enough and cast easily. Even range lead which runs about 2% antimony and negligible tin, or straight wheel weight which are about 3% antimony and negligible tin have been used for years by members here with satisfactory results. As a hardening agent antimony is far better than tin, but a small percentage of tin improves toughness and castability.
