Ever watch any hunting vids with the "verminator"? Can't remember his name, Randy Anderson is usually hunting with him though. Anyhow his set up is a Ruger 10/22mag. with a video camera mounted on top of it to video his own hunts. I've watched him, on this dvd I have, shoot several coyotes with his 22 mag. Not head shots either, lung shots.
Wouldn't be able to take real long shots b/c of the 22mag. losing power so quickly though.
Think about a .17 HMR? Good on chucks, good on squirrels, head shots on 'yotes. I tested the .17gr. v-max on a deer skull I found in the woods. Wrapped it in some wet rags to give the simulation of skin to. It will easily penetrate the skull then it fragments and would to all sorts of horrific things in his dome. :eek:
