I agree with the instant death, no doubt. I do plenty of gopher shooting in the summer and many head shots result in the same. I do have squirrels digging in the wives flower pots and have contemplated baiting them but would prefer a heart shot and just drop them without the death dance.
So if you do some vitals shots, would be a good learning tool for those who are interested in that kind of shot placement.
Perhaps my post sounded a little critical, sorry.
Good vids, I watch all the time.
