If we are talking coyotes, you should seriously consider using a 12gauge with 3inch #4 buckshot loads.
That.17hmr is just to light to guarantee quick kills.
The .17HMR will work but I would take headshots and get them 100yds or less. A hit anywhere else would give less then favorable results.
There is also a 20gr hollow point available for the .17HMR but out of my rifles they are not as accurate.
