Thanks for posting that Mule Deer. And nice looking CZ. Stock looks much better than mine does.
OK! Thought it might be of interest to some.
Owned a CZ 455 heavy-barrel at the time, which grouped well but not like the 457. So the 455 was one of the .22s I sold after getting the 457.
Might also mention that because the heavy barrel is relatively short, the rifle only weighs 7 pounds 13 ounces with its present scope, a 3-9x Burris E1. Also own a CZ 452 Sporter .17 HMR, and it weighs just about exactly the same with a similar-weight scope. The 457 does hold a little steadier when "hunting" ground squirrels....
