Lebomm, or Larry, I only used the plumbers lead to slug, and also to "lead" or soften the bullets I tried originally, as the BHN was way too high. They were from some other bullets I made for my 44 mag. Now I've got some bullets in the 11.5 to 12 (been sitting a while and probably hardened to 12 or so). I'm gonna try these, but haven't gotten a chance yet.
