I once tried to find a rifle chambered for the 22 short only, thinking it would make for a more accurate plinker/pest remover. Never found one, if one exists, the availablity and price I'm sure would not be practical. So I used Super Colibris in my Kimber Hunter to knock off dogfood stealing, excess numbers, squirrels (a few are nice, but not dozens), and grackles. Got tired of taking out my decent Kimber and getting it dirty (handprints, dirt, powder residue) whenever opportunity arose and then having to clean it up for storage, and then have another opportunity pop up. So, now I keep my better rifles for target and intentional hunts. For the backyard shots I bought a Cricket single loader at walmart for 100 bucks. With it I can knock off tree rats, grackles with the the colibris and not worry about cleaning, care, etc. Gets the job done.
