When it comes to varmints, I've never given much thought to their survival. Blow 'em apart with 204 Ruger or wound them with a 17HM2, they will eventually die and be eaten, thus completing the circle of life think. I have seldom bothered to pick up dead pdogs or gsquirrels, unless the land owner specifically asked me to do so, and when passing those same killing fields on the following days, I never saw any bodies festering in the sun. After all, protein is protein to a scavenger.
