I never thought of lubricating molds when black powder casting. I guess I just didn't do it enough to matter. So started regular bullet casting and a lee 452 6 cavity was my first and was told to lube with beeswax. Yes it worked but it burnt all over it. What is the best way to clean it now?
I think next one will use 2 cycle oil lightly on it. I have a NOE 311 185 grain one in the USPS now.
