I carry my CZ-52 sometimes too, just for fun. I OC a lot, mostly because I really do not have any small weapons. Open carry is not a problem up here where I live, and if it gets covered that is OK too, I have a CPL
I have the same over penitration concerns about the Soviet surplus ammo I have. I was looking around and found some US manufactured SD (hollow points) 7.62X25mm that sounded good. (1700fps/500ft lbs) Haven't purchased any because I'm not sure how well they will feed in the 52, but I would think a hollow point would be less likely to exit the target and do as much damage beyond as a FMJ?
My second problem with the 52 is the sound level. My hearing is toast already, it doesn't need any more help getting worse. It would take a lot before I would consider actually firing the 52 in a SD situation though I am sure I wouldn't be thinking of my hearing if that kind of a situation ever came up. Our biggest problems here are 4 legged not 2 legged. (Think Black Bear)
Just got back in from shooting (and then cleaning) the 52 as well as the Trophy. (We just shoot here in the back yard). The mountain was filled with the sound of gunfire this weekend. There were a lot of people out doing the same thing today. Beautiful day, and the first one this year over 70.
Battle Creek? Washington State? I know where Battle Ground is, about 350 miles SW of here, I know where Battle Point is, but do not know where Battle Creek is??
