Nice pictures C I. I have a different version of the CZ 457 that's become my 22lr fun bolt rifle by a mile. Right now it has too much scope on it, fun for the bench but bulky. I have stashes of good ammo, but I pretty much shoot that red box SK, and CCI standard velocity. Aguila standard velocity though has surprised me as being similar to the CCI and may throw less fliers for me, when it comes to cheaper ammo.
