I'm new to shooting cast bullets.
I will be shooting in a 7.62x39 at around 2000fps.
The bullets are gas checked 12 BHN (94-3-3).
I don't shoot that much at a time. Maybe 50 to 100.
Can I run a few jacketed bullets in the mix to scrape it out?
What am I looking for to know if leading is occurring?
Thanks.
