I've been the 17 hmr route a few times for the exact same uses that you intend to use it for. After a few different shots at it, I decided the best 17 is a 22LR. I know the 17 is faster and flatter and a little more accurate but with cost of ammo and the prey you are after a 22LR just works better for me. That's my .2cents and worth about what you paid for it.
