I can get 3500 fps in my Rem.700 222 Rem., with a 20" barrel. I've shot a couple coyotes with them. You just cannot hit them in the shoulder bone, or you won't get much penteration. And in 2' of snow it no fun chasing a 3 legged coyote in a swamp all day. In the ribs they fall dead or do a little spinning. We have red squirrels, that are smaller than a prairie dog and it blow them to pieces.
