I'm a HUGE .22 mag fan, and own and shoot/hunt with them quite a bit. I'd suggest a 4x-16x or something along those lines. With that magnification range it's plenty low enough to have a wide field of view for running shots or quickly taken close range shots, and with the scope cranked up at upper end it permits me to see bullet holes without having to resort to spotting scope or walking back & forth to target to check shot placement when shooting from bench to check zero and/or group size and long shots (100-200 yards) when hunting. I've found scopes offering that range (4x-16x) work best on .22 mags for ME personally.
