A good friend of mine has a CZ .22LR and it shoots VERY accurately. I own a .22 Magnum (but Marlin, not CZ), and comparing the two calibers, I'd say your little CZ should serve you well. The only drawback to the .22 Magnum is the price compared to the .22LR. Around my area, .22 Mags cost 7 dollars for a box of 50 ct, compared to the 98 cents for "top end" .22 LR. You said you have the varmint version, but I've not memorized CZ's product line. If you have that short, funky shaped European stock, you might find the truncated fore-end annoying. On my friend's CZ, they placed the Swing Swivel mount right where you naturally want to place your hand to grip. Very irritating. At least for me. My friend just adjusted his shooting habits, but I would take the mount off, or get a different stock.
