I noticed it always us in the little 10mm club.....
I would also like to get some 10mm data for my glock 20,as i'am getting bulging (enough to toss it after 1 load)even on new brass and velocities lower than i had hoped for.I didnt find as much info as i had hoped on those other sites.
I have heard of guys shooting 180grain bullets to 1400fps but that's way over max load. They are probably shooting the 6" aftermarket barrels. Slower powder, more chamber support etc.
