Theres a guy around here called "Lead Miner". He has a semi-truck and hauls lead around the midwest. A group of us went in on a barrel, but he also sells loose quantity. His stuff is good, clean and no grit/gravel. Don't know if he has a website. Friend found him on "Trapshooters.com" I believe. We've had good luck with re-claimed shot for skeet and sporting clays. I figure the few in each shell that are flattened or stuck together gives me a "hit" where I should have missed..haha
