I have stated this before......FORGETABOUT the .17-HMR!!!
My vote goes to the .222 Remington or the .223 caliber gents.
Also the .243 does a great job too! I like it a lot on "song dogs" (Coyotes") around our place.
Great calibers for coyotes but a bit harsh on fox. Especially if you have alot of close shots.
I absolutely agree with the 17HMR. Unreliable at best.
