17HMR if you are looking for gilt edged accuracy/precision on targets and good explosive power on small critters like ground squirrels. One of the most consistently accurate rimfires I've seen. I use one for some shoots that require speed and accuracy to dominate the competition. In some events where they specify "rimfire only", the 17HMR is almost like cheating. Just a FYI..

22WMR if you are chasing animals up to the size of coyotes.
