I shot one 250 or so pound boar with a 45ACP, that was still breathing after I hit him with a 308. I shot him with the 45 in the back of the head from 1-2 feet away with a 230 grain gold dot from a Kimber commander length gun, the pig quit moving very shortly thereafter however as far as I could tell the bullet did not go out the bottom of his head. The gun was near horizontal, the pig was laying on its side, and I was squatted down next to it.
