I'm looking at getting a single action army style revolver and am torn between 22 mag and 17 hmr. There are both calibers available on buds for cheap, by either heritage or Chiappa. On Chiappa has the 17 hmr but it's only 5 bucks more. It would be mostly for plinking but I'm also curious which would be more effective as a manstopper if it came right down to it. The .17 seems a little gimmicky in a revolver but for 160 bucks I don't mind taking a chance on a gimmick. Logic says the heavier bullet would win, but from what I've seen with varmint hunting etc, 17 hmr seems to do more damage than 22 mag. Any thoughts or experience?
