Well, CZ rifles are great for the money. I haven't had on in .17, but I have had CZ .22's, 22 Magnums, .223's, 30-06's, and .308's. They were all great. I expect a .17 CZ would be the same story.
KS&E on Pendleton Pike had one for sale the other day. I can say, it is probably the best price in town.
The only thing I will say about them is, don't order one online if you care about the quality of the wood figuring. The wood on a CZ can vary greatly from one gun to another. I am a sucker for wood, so I like to pick my CZ rifles in person.
We have two 452s in .17 HMR and they are both proverbial "tack drivers". Easily under 1 MOA assuming calm conditions. I'm going to assume you're talking about the newer 455 and I think they may have the set trigger. Mine don't but I have installed Brooks trigger kits in them. The Yo Dave trigger is the same thing if you need it. Great guns!
I don't own a CZ but a buddy of mine swears by them. I think he has a CZ in every caliber that they make and they are all tack drivers. He loves their .17HMR.
