I LOVE CZ'S!!!!!!!! I'm about to buy a CZ 452 american 17 hmr to replace my 17 hmr Savage Classic T. I'm also saving up money to buy a CZ 550 American in .30-06, .270, or 6.5x55 (I think that's all they offer for the gun LOL). I'm having trouble deciding between the calibers. CZ 550's are extremely durable, reliable, and accurate rifles that utilize a mauser style bolt. You can't go wrong with one.
