mn--17HMR,
Here again, IF you take head shots only and keep your shots inside 75 yards....it's possible. A clear-open-standing still-squeeze the trigger-behind the ear-in between the eyes shot will do the trick.
A chest shot on a coyote with a .17HMR is a high risk shot, at best. It's possible to kill one with that shot, but it's definately not in the high percentage of probable kills.
Cats can be resilliant, even though they're thin skinned critters. However, a good head shot takes most of them down. /ubbthreads/images/graemlins/cool.gif
Fox are thin skinned critters too, but don't seem to have the resistance that cats and coyotes do for surviving getting shot. /ubbthreads/images/graemlins/laugh.gif Chest shots will work, but I'd stick to the head shots for sure kills. /ubbthreads/images/graemlins/smile.gif
I speak from experience, when I say that it's a bad feeling to shoot an animal and watch it walk off wounded. /ubbthreads/images/graemlins/frown.gif I prefer overkill, in my weapon choices. However, often you use what you have and get by until you can afford better. /ubbthreads/images/graemlins/wink.gif
Good hunting, Bowhunter57
