I'd go with a .17 HMR, but if you REALY want a .22 rimfire, I would get a Ruger 10/22. I have a Marlin, and it has a tube magazine, its a real pain in the @ss to unload, and reload everytime you get out of your vehicle(i.e. coon hunting.) My brother bought a Mossberg .22 Plinkster, works great, and only about $100. If you do buy a .22LR, I suggest getting a Red-Dot sight, or a scope.
