Come on SHOOT it, even better do it at an indoor range!!
Back in 1991-92 I used to shoot the military ammo indoors, flames coming out the barrell 3 feet, the LOUDEST bang there was. As soon as a crowd gathered arround I would slip in a magazine full of Fiochi Boxer ammo. I would then drill the magazine inside a quarter or less sometings. (could never do that with the military ammo)
Now the local Clark County Las Vegas gun range has night shooting on Wednesday night. If I am ever home on a Wednesday I am deffinitely taking the CZ52 first, and maybe I will have my 1911 in 7.62x25 by then too.
Once in a while I loaded the reloads a max, just awesome bang. But the j=gun always shoots more accurately with 1200 -1300 feet per second loads. I had a Marine sniper shoot it inside a quarter at 25 yards so I know the gut will shoot better than I ever could.
But the CZ52 is just so much fun, you got to shoot it.
