I just bought one of the CZ's in 17 HRM and scoped it up yesterday and went straight to the range with it. I am very impressed! I live in Wyoming and as usual, it was windy, but the wind didn't affect my groups at 100 yards. I was getting sub-MOA right off the bat. No jams, no problems whatsoever. Can't wait to see what it will do on prarie dogs. And the price was good too. Haven't been able to say that for a long time.
