[QUOTE=bigcountry;3600554]Bottom line is, you have an unsupported part of the case. Thats means, load at your own risk. i load starting loads with my G21 and use +P starline brass. For months, I took notes with a micrometer measuring any expansion. I am sure I could go more.

But I decided to nip it in the bud and just get a bar sto bar match barrel. That way I can shoot until the brass cracks if I want.[/QUOTE


well thats what happened when it exploded in my hand, the brass had cracked and i had to pull it out with needle nose pliers. to me that was too late. so whats the most, rule of thumb if u will, ya want to use the brass?
