I suppose they could be used if you have a method of melting them down..And I would like to know how hard the alloy is as it may ruin your barrel...I have shot bullets cast from babbat with no ill effects..Let us know how they work..John
Babbit is fine because it is lead-based, and AFAIK the various babbit mixes only use acceptable lead hardening metals in the alloys: tin, antimony, copper, bismuth. Coins, though, mostly are zinc-filled these days, and while some folks cast zinc, it is a bad contaminant if it mixes with lead because it raises the surface tension, interfering with mold fill-out.
