look at a Ruger 10/22 perhaps the best 22 rifle ever made
Perhaps NOT too. They're fine rifles and you can make them into great rifles but it will cost a bundle. A CZ is a very nice bolt action rifle that will shoot great and look great for a long time to come.
My CZ is a 453 though. I love the better trigger and despite what people say, I've never seen a doctored 452 trigger that is anywhere near the quality of the 453 set trigger.
BTW from what I understand the varmint barrel on the 452 is a waste and a lot more weight to carry around. The sporter version shoots just as accurate and won't wear you out carrying it around all day hunting. Besides that it's getting hard to find 452's since they have stopped making them. The 455 is replacing the 452.
