TJ can't help you with that particular model but I do have a 452 in American classic, they are just called American now but used to have the classic bit as well, but it transgressed someone else's name registration or some such thing. Anyway the 452 is the most accurate 22lr that I have ever shot. It has been responsible for more rabbit deaths than mixi!
It is not overly fussed with ammo but I prefer the Eley subs, and have taken rabbits out to 110 yards with this combination. It feeds well and I fitted one of those Eric Brooks trigger kits, all it means is changing the spring really and a sleeve to use if you suffer with trigger creep. As a bonus it has a nice stock as well, it impressed me so much that since I got it I have bought 2 other CZ's. I really think that you cannot go wrong for the money.
