I'd like to get a single action revolver, full-size frame, in .22 l.r. for practice to cut down on cost. I shoot both Ruger and SAA-reproductions in centerfire calibers but would like to get a rimfire for cheaper practice, something similar in size and weight so skills gained will be more easily transferred to my centerfires. What is recommended? I have little experience with rimfires in either Ruger single actions or SAA reproductions. I'm looking for accuracy and durability. Any suggestions?
