I picked up some lead from a scrap yard, which I was told came from a gun crank's estate. These are 1 pound ingots, from the Lyman ingot mold. The guy thought it about 14 BH, and I have purchased lead from him for many years, good guy. When I put it in my RCBS furnace @ 760F, the dross was light grey, almost like lead whipped cream, and granular. Nothing like comes from wheel weights. The lead alloy was also had a thicker viscosity to it, so much that it would barely flow from the bottom port. Wheel weight lead comes thru at this setting very well. Has anyone had any experience with this sort of issue. This was a 10 pound trial run, bullets always had a wrinkle to them. I increase the heat to 790 and no difference. Then added 1 pound ingots of 8 Hb lead in an attempt to dilute. Not much help, I was able to get a decent shiny bullet using the Lyman dipper, but not from the bottom port.
