I use pewter as my standard lead enriching material. Traditionally, to be legally called pewter (stamped on the bottom of the article) it has to be at least 82% tin, and no more than 18% lead (safety reasons). Modern pewter is lead-free, being 97% tin and 3% antimony (Selangor Pewter Company).
Tin/pewter by itself would not be that great a bullet alloy, but mix it in 1:20 with wheelweight lead and you duplicate Lyman's alloy #2, which is 90/5/5% lead/tin/antimony. I get all the wheelweights I can carry whenever I go to the tire garage to get service. You just need to melt down the weights, skim off the metal clips, and add your pewter 1:20 w:w. Here's a pic of a 9mm cartridge I made with a Lyman 358477 bullet. It looks funny because it's a revolver bullet designed for the 38 special, but it weighs about 147 grains cast in #2 alloy and shoots great sized .356".
