Hi everyone, I'm new here. I've been reloading for a few years and have decided to start casting for .45 Colt. Lately I've been reading a lot of great info here on Cast Boolits, and have learned a lot! I have some muffin tins that I plan to use for lead ingots. Some of the muffin tins are aluminum and some are steel. I've read that sometimes the lead welds to the muffin tins and is impossible to get out. What if I use some mold release spray on the muffin tins?
