I have a CZ453 American in 22LR. I agree they are nice guns. They look great and carry 'almost' as well as the Ruger. Not quite as handy. A nice option to consider for a wood stock classy and classic gun. If you can find one a 452 or 453 American.
I would not expect to be within a dime at 50 with any 22mag. That is 5 shots under 3/8 at 50 and really requires a bit of luck. I think anyway. Not been my experience with 22mags to see that level of accuracy. For me, that has required some quality ammo in 22LR and a very good rifle. You can call me a bad shot or hack , but my CZ American in 22LR with best ammo to date, is eeking out maybe 1/2 at 50 for 5 shots.
When I test for accuracy in 22LR, I shoot 10 groups of 5 shots at 50 yards. Many shoot 10 shot groups. I take the median group. Nothing is thrown out. No excuses, it all counts. In 22mag, I pretty much consider that a waste of time and ammo. Group sizes are larger. That is my groups.
