If you're set on a revolver, and that's fine, I can't help.
For an auto, the S&W 41 is a nice gun. The
Browning Buckmarks are also nice, as well as the Rugers. We have guys at our club using all 3. If price isn't an option, there's also Hamerli. Finally, there's High Standard, which is my pick, but you have to really love them as you may have a problem with feeding of different types of ammo.
I'd have to ask the use to recommend anything. For carry, as in hunting, you're probably right about the revolver. I wouldn't dare carry a .22 target pistol (as all of these autos are) in a holster. Maybe I'm just a weenie. For use in learning how to shoot, or for informal target practice, I'd go with an auto. Not that they're any more accurate than a revolver, but they usually have very good trigger pull right out of the box, are usually very reliable, have nice sights (except some of the Brownings), and you don't have to **** the hammer each time. (Forget using double action if you're doing target shooting, IMHO.)
Some of the guns have optional really long barrel lengths. For accuracy, and sight alignment, about 5" is about right, longer won't help, and most find them harder to use. (Exception being if you're going to shoot with some sort of rest.)
Sorry for the long post...
