I love the 17 HMR but I don't use it for coyotes, bobcats or fox. Not saying it wont kill them when you put the bullet in the right place. I use mine for Grey Diggers, Sage Rats and close in P-Dogs. Not for Silver Greys cause it blows them up to bad.
If it is all you have or can use I say use it, just be sure of your shot.
I wonder how the new 17 Rim Fire will be for coyotes say up to 125 YDS.
