When I first started casting (60's&70's) I had only read a few Gun magazines and knew nothing of casting. Computer forums didn't exist and casting technology was in it's infancy. Linotype was on it's way out so that became easy to find. Truck stops were giving wheel weights to anyone who would take them off their hands. Underground telephone cables were giving way to technology so lead coverings were very cheap from phone companies. I used straight lino or wheel weights or an unknown mixture and was happy. I even threw a few sticks of 50/50 in the pot whether it was needed or not. Of course things have changed considerably these days. I'm 83 with more parts replaced than my car so my shooting days are over. I have about 20 large coffee tins filled with cast bullets for my .38, .44 ,.45 & 45/70. Anywhere from 20 years old or so . I know their size but have forgotten the particular alloy. How do I get rid of them. I was thinking of melting them down into an unknown mystery alloy or selling the cast unknowns as lead, not bullets, and let the buyer figure it out. What to do? Any suggestions from out there would be appreciated.
