A BB gun will kill coyote, and one of the biggest brown bears ever killed was shotwith a 22lr.... Neither case makes them the right rifle for the job though...

I'd rather have a 22 WMR in my hands for coyotes anyday than the 17HMR, but it doesn't mean the .17 won't kill them.

Will it kill one? Of course it will, should it be called a "coyote rifle", NO.
