I have a 455 stainless in 17hmr. Very accurate and a really handy rifle. Its my favorite rimfire I own. Or at least the one that goes to the woods most often.
I got it on close out when they were discontinued for about $350 and I wish I would have bought several more. I also bought a CZ factory barrel in 22 mag at the same time. I've actually never used it but it was cheap and figured it be good to have since I had 22 mag ammo on hand. Seems easy enough to switch over.
If you get tired of yours let me know and I'd relieve you of that problem!
