Somebody help GLW
GLW,
All I know about cast bullets is what I learned making .58 cals in a Lee mold for a muzzle-loader I used to have (30 years ago). I used pure lead, and I bought a sizing die that I could push all my bullets through, because I never managed to get them all the same size as-cast. I had been a foundry metallurgist shortly before, and I knew how important lead temperature and mold temperature would be for sizing and quality.
