This guy is just looking for a reason to buy a new rifle.

After the .308 he will tell his wife that he nicked the Coyote's paw and it still ran off.

Then he can say "honey, the .308 is no good for these Californian Coyotes"

I need a 50 BMG for close range and a .338 Lapua Mag for the ones that are a little farther.

Wifey says "you don't want to hurt the Coyote" Go ahead!
