I use a .22wmr when calling most of the time.But I love my .220 swift.

243! 55 grain hornadys... no pelt damage... cant go wrong! I do love the 204 as well!

.204 shooting Hornady 40gr. V-Max. Does the trick:)

I use my Bushmaster AR-15 .223, or my Remington Model 770 30-06 when im feelin manly.

about the only calibers good for BOTH fox and yote, if your saving hides, is the 17 rem and fireball, and the 22 hornet..fox are tiny little critters...nothin but furballs and have a pretty thin skin on them...the bigger centerfires will almost always make a total mess of them...

In WV, we are very limited at night. It's coyote only and must be no bigger than #4 shot with shotgun or rimfire rifle.
I would like to have a dollar for the coyotes running these hills w/ turkey loads in them. If legal where you are, you can not beat #4 buck 3 1/2in through 12 ga.
