"Now, if you look on this one you will note that the rear of the lower jaw is not that far from a brain/brain stem shot (ear) and just a little raise of the head right when you start to squeeze off you will hit that instead of a brain. http://boarmasters.com/wp-content/up...placement1.jpg"

I would call where you're talking about the far back hinge of the jaw and not the jaw itself. That is a big hard area and if you missed and hit that area he's still going to go down from shock to the spinal column and that would allow another shot before he could get out of Dodge. I've never shot one more than one time and every one went down, but all were in very controlled circumstances compared to your style of hunting them on the ground in big numbers. I'm a long way from your numbers because they were always an incidental animal to what I was down in Texas to hunt and I've only shot one down there in about the last ten years on a turkey/hog combo hunt to get my Dad out one last time a few years ago before he died. Anyway, we're on the same page in that I was deer hunting when I shot all the hogs I have, so mine was not done on the ground looking for them and wanting to wack as many as I could like in your scenario. When you're up in the air in an enclosed blind hogs are pretty easy to shoot like I have done if you just wait for the right opportunity. If it didn't come it was no big deal when the quarry was actually a big whitetail buck down there, so I was pretty choosey on what I shot in the hog department. I know one thing and that is I never had to change my drawers because none were going to charge me while I was up in one of those Texas towers, LOL!
