I've been lusting for a CZ bolt for the better part of a decade now.
I'm not that good a Shooter to attempt the 1/2" challenge so the purpose of getting one is to appreciate the beauty and craftsmanship of a CZ. That said, I'm happy with the accuracy from my Savage MKII TR and S&L but one day I'm going buy that CZ........
If you're looking for the best CZ experience, I'd suggest a 452.
Imo, the 455's were good rifles, but not quite up to the same standard as the 452's.
The 457's have left me cold, which is probably why I'm now shooting a walnut-stocked Tikka. It's quite capable of making the 1/2" challenge, unlike its owner.
I still have a 452 Varmint in .22LR, the only other CZ that would tempt me would be a 452 full stock.
