L D, and others, on the board;
Sue me if you wish, but don't hold yer breath on collecting, as I am pretty much 'judgement proof', like in, no tangible assets!
Seriously, the CZ 52 locks up in the same fashion as the Schmeisser MG 42, and that represents a lot of engineering!
Only an idiot would feed any arm a diet of 'proof pressure' loads, long, or short gun.
I will tell you that the CZ is among the strongest pistol actions going, and that I have witnessed 40K pressures, without failure; I'll also add, "Don't try this at home".
My personal philosophy is to use the lightest load that gets the job done, to minimise wear and tear on the weapon, since I get to pay for all of my mistakes!
Enjoy the 52, load for it conservatively, and it will outlive all of us!
Don't start no s**t and there won't be none, Terry
