When I started casting I purchased some tin and pure lead from John Walters. Short while later I picked up a couple hundred pounds of Linotype from a fella here in the 'Fire. Along the way about 300# of wheel weights came home from a garage, and I was set. Then a friend needed help melting down a couple loads of roofing lead. Another couple hundred pounds were left as a gift.
I'm kinda particular about alloys and don't pick over the backstops etc.
AND I DONT NEED MORE LEAD. I figure 1,200-1,500 # is going to last me a while.
