Do you guys recommend WD when PCing? I read about the lead being changed with the high degree of heat. Is that an issue? Another question is the temp that you heat these up to, some guys that PC small parts talk about 350 degrees for a heat. Here it's 400 degrees as the number. I'm not sure if the lower temp would cause less of a tempering issue. ??? I am so excited about this PC idea. I love it. It's the easy answer to cast boolit issues. Makes some might nice looking boolits to.
