As long as there isn't "to much" cross wind
I tried the .17 HMR, while accurate and fun. I found myself back to just using my .22 Mag, so I sold the .17 to a friend. For his youngest son to shoot.
Seems to me the .22 Mag is more versatile, it can be had in a convertible cylinder revolver such as a Ruger single six.
