I have been wanting a semi auto .22 mag for a while now. I was less than impressed with the Remington 597, and am not willing to pay what the 10/22 mags are bringing, so I picked up this CZ-512. Accuracy is impressive, it easily outshoots the Marlin 882SSV bolt gun I had. Reliability has been 100% so far with Fiocchi 40gr PSP, and CCI Maxi-Mag 40gr FMJ. Fired the 5 shot group in the photo this afternoon at 100yds at -3 F, with no wind (sorry for the blurry pic, that is a dime). The trigger could be better, it has some creep and is about 6lbs. The trigger is my only gripe, and hopefully it will smooth up with some more shooting.
