I use my .17 as an all purpose gun. That is, its the rifle that I prefer to have with me if I decide to just go tromp the woods for a while and take a shot if something comes up. I use mine primarily for crows and squirrels. If you keep to head or shoulder shots on squirrels you won't ruin them, at least I haven't. I haven't taken a shot at a coyote or fox yet, but would be fairly confident with the .17 on them up to 100 yards.
