Fired 200 rounds in my CZ75 today. With BLL and a bullet, cast from range scrap, sized .358 I had minimal leading. Most of the lead was pushed out with a damp patch. I have had far worse with regular lubes in this gun.
I want to heat treat some of these bullets and see what difference that makes. Might be better, might be worse. I will find out.
I feel encouraged by what I saw today.
UUUmmm, sounds like you're making some good progress with BLL.
