I've a CZ52 that really has me puzzled.   Gun is nearly mint, perfect bore, well over 95% of the orig. park finish...Action is smooth, trigger light.  Problem is that at about  15 yards the damned thing will NOT group any better than about 2.5".......at that it throws everything to the left of POA.   No, its not me.   Everyone else that's shot it experience the same result.  

Loads have run the gamet from S&B, Czech. mil, numerous handload combinations with cast bullets.   I am a very experienced handloader, having played that game for well over 40 years.

Since this is the only 52 I've ever used and since I have repeatedly read comments on the superb accuracy others experienced with the model I gotta ask for some opinions before I buy another tube....What say you????

I don't have a CZ52 so take my answer with a grain of salt.

I've heard many CZ52 owners say that the gun seems more accurate at 100 yards than at 20.  I don't know why that is.

Did you get it from centerfiresystems?
