Fl, I also make my own lead bullets. I have made most of the common calibers.. 357, 9mm, 44 Magnum, I also use and make more of the 45 Colt, 252 gr SWC shoots excellent out of my Ruger, also 45/70, 450 gr FN I shoot that out of my Handi Rifle, and I use a Lyman conical mold 370 grain for my CVA muzzleloader.
What are you making? Also when I pour the lead I normally do it outside or in my garage with both doors open to get a flow of air, I am concerned with any lead hazard from breathing it in. I also go as far as wearing a mask that filters out any of the lead.
