One consideration with the CZ model is the bolt handle lift. The 452/455 can have some clearance issues with the eyepiece on larger scopes if you like them low. C457 action is similar to the T1x with a short lift.
I have 2 x 455's and neither bolt handle hits the eyepiece tube but it is close on both (less than 1/8").
My T1x in 22 has loads of clearance, would be the same with a 457.
