Hi all,
A co-worker came through for me today. She remodels / flips houses on the side and I asked her to keep an eye out for lead flashing, pipe, etc since I cast my own bullets. She said she had a big lead "door stop" that she would bring me. A couple of weeks later, today, she finally remembered to bring it in. I was expecting a 15-20 lb block, but no, this thing weighs 54.2 lbs! I suspect it's pure lead, and can't wait to cast some to get a better idea of content.
Good luck to you all in your search.
