My best friend is giving me 20 or 22 lb lead bar ok. He got it from his brother in law and he asked him for me where he got the lead he used to melt down to make the big bars. He works for a construction company and they had torn down an old hospital exray room and his boss gave him and some others the lead blocks that was used to make the lead walls. I dont know how much he got or anything all I do know is he said it was safe. Is this type lead good for casting? My best friend is using it in his 44 Mag and has no problems with fouling.
