I have started trying to collect lead... Wheel weights seem to be hard to come by atm, but I'll keep looking. One suggestion, check out any harbours, marinas etc. I just got a line on a lead keel from a sailboat. Gonna test the hardness and pray that it's not full of zinc, but I think I can get him to chainsaw me a few hundred lbs. trying to keep it under $1/lb.
Also, try making friends with a plumber, they seem to find old lead piping during renovations
