So I'm still new to this. Had Accurate molds made up for my 8mm Mausers closer to the .318 groove. Cleaned the mold with brake cleaner twice. No luck casting. Probably cast more than 50 Boolits and every single one has wrinkles. Alloy is stick on weights already hand sorted and melted down with a turkey fryer. Cast into ingots. Positive there's no zinc. Just wanted to test the mold and figure it out on reclaimed lead rather than spending the cash on rotometals. Soon as I get the hang of it I will get harder alloy from them. Ingots were melted down in my Lee 4-20. Have a PID set at 750*F, Lyman digital thermometer read same. Even pre heated the mold. I just don't understand the problem. I think I'm moving along at a decent pace, too.
