Several years ago Gun Tests did a review on the Cz in .223 and i believe another model in cal. 270. They gave both rifles a very favorable review and if memory serves me right the .223 shot very well in the tests.
Just remember one thing. Although the Cz is a nice rifle, spare parts for it have often been scarce to non-existent. A Remington or Winchester or Savage may not be as glamorous but spare parts for these guns will be around for a long time to come and they are not hard to find.
