Ironically my dad and I had a talk about this Saturday afternoon, we are both members of the same forum that you mentioned. I constantly use a shotgun to kill hogs, the difference between me and this other kid Texan is that I don't use bird shot in my shotgun I use 00-8pellet or 00-12 pellet (12 or 10, I don't have a box handy) in my 12 Gauge. I also use my .357 when the chance presents itself. However, I always shoot to kill, or at the least put it in it's tracks and come back with my pistol to finish it off. I disagree with what the kid did, but at the same time, I have seen first hand what a freshly plowed wheat field looks like after a group of hogs have gone through it, total destruction. So I would say that he should have concentrated his fire on one pig, it is possible to put 5 shots into it before it gets away. They rarely return to the smell of blood or sound of gunshots for a few days, leaving you plenty of time to go and get better fire power before the next round.
