I have more than a few 22 rifles. By far the most enjoyable is my old Winchester model 63 (fitted with an old Browning 4X). The gun is very accurate the trigger is amazing and you end up with something that feels as nice as one of your old revolvers. A shooter grade 63 won’t cost you much more than a CZ and will likely be worth much more when you hand it down to one of the grand kids.

If you want to go off the shelf and keep the cost low 10/22 is hard to beat.
