I agree with Wirehair, stick to a bolt action. My wife had a Ruger 10/22, you cant get any sensible grouping with a semi auto, it's hard enough judging range and compensating for the trajectory of a .22 sub. We put it in part exchange for a Sako Finnfire, A excellent tool if rimfires are your thing. We also use a .17HMR rim-fire which is a c.z with no complaints.
