After being without a .22 R.F. revolver for awhile, I picked up a three-screw Single Six last November at a gun show. I've been through a number of .22's and always fall back on the single action. One of my all time favorites was the little Colt Scout, a lightweight single action. This proved to be a dandy squirrel gun.
But a good single action rimfire is as good as it gets for small game and plinking. Another favorite of mine was the Super Single Six with adjustable sights and auxilliary cylinder for .22 WMR. At that time the .22 WRF was more readily available and I used these for many squirrel hunts. The .22 WRF was a little larger cartridge and easier to handle with cold hands.
