Late teens, load'em hot and let it roar.I agree but my grand kids are in there late teens and get a kick out of shooting it
Hell, you can use Trailboss in a 300 Blackout. Get some of the 45 Colt cases that are shorter than the normalThanks everyone and as far as the Trail Boss I have looked into that but it seems all loads are for lead bullets that I have found.
