I have a 17 HMR and have been totally satisfied with it. I have a heavy Savage and put a 3x9 scope on it. A 17 is a great little round, but I think too many people try to make it something that it is not. If you are going to shoot a coyote with it, you had better shoot him in the head or square in the lungs, or you might see him go over the hill. It is very accurate and so is good for head shots on small game and although I have not had the chance to try it, it should work real well on foxes and bobcats.
I set a dog-proof coon trap about 130 yards from my house. If there is a raccoon in the trap, I can kill him from my deck with the 17 without a hitch. I think the small bullet actually works better at that range than up close, as the little bullet does not fragment as violently at the lower velocity.
I think the new round may be a super rimfire if they can ever get the bugs out and start putting good rifles on the market. I would buy one in a heartbeat if this happens and ammo starts showing up. I am just afraid that it will go the same route as the 5mm Remington did if they don't start getting it together.
