I have had several 452 models and one 455 all except one of the 452's were 22 lr's I did have a .17 M2 452. I'm not going to swoon over how great they are, every one of mine had ejection issues from the factory not 100% reliable and I don't think the creepy factory triggers are "fantastic" when compared to some higher priced rimfires I've owned, accuracy was good with every rifle but I wouldn't say any of them were what I would refer to as "tack drivers"...I will say this about CZ bolt action rimfires.... For the money these rifles are the best buy on the market and by a pretty good margin, but not the best rimfire rifles available by a long-shot..........Hb
