A Few Comments on Cast Bullet Alloys by Glen E

Antimony hardens lead alloys much more effectively than does tin, and is cheaper to boot, so antimony is the primary hardening component used in lead alloys today. In addition, antimony allows the alloy to be hardened via heat treatment, something the chemistry of tin doesn't allow and arsenic is even better for heat treating than is antimony .
