We don’t have feral hogs where I hunt, so I have never hunted them. But, if I did, I’d aim in the way that ensures the quickest death and most likely recovery. Your experience may be different, but the pigs I have seen don’t have long necks, unlike deer, so they don’t move their heads in a way that can quickly turn an instantly fatal shot into a catastrophic wound. I would still prefer to take shots at the largest vital area.
I suspect, however, that many people view feral hogs - or predators - as vermin and don’t particularly care how horribly they die. And, as far as I can tell, a lot of people don’t eat them and don’t bother to recover them.
I certainly never much care to shot placement on a groundhog. I aim center mass and squeeze the trigger. The varmint bullet takes care of the rest. Anything that’s not lying on the ground after the shot counts as a miss.
But, I shoot squirrels in the head because it is the best way to ensure recovery with minimal meat loss. And, the way squirrels move, it makes for a good target that doesn’t move much. Unlike deer, they don’t move their heads in a way that can quickly turn an instantly fatal shot into a catastrophic wound. At ranges under 50 yards, I am unlikely to miss, especially given the amount of time I have to take a shot on a squirrel. Also, hitting a dime-sized brain isn’t much harder than hitting a quarter-sized heart and lungs.
If I could arrange for deer to stand still, at 50 yards or less, while I calmly aim and blow their heads off, I might plan on taking that shot more often. But given the choice between hitting a volleyball or a golf ball, where only raw hits count and there are no points for taking a harder shot, why risk it?
If you need two points to win and have the time, there’s no point taking half-court shots. I lump most people who *brag* about taking headshots in the same category as people who *brag* about taking long shots. Many of them seem more interested in proving something about themselves than in considering the best way to ensure clean recovery. That’s not directed at anyone in particular, just a general observation.
