Resources on wild pig management usually recommend trapping or baiting rather than trying to shoot them. Shooting at them with a semi-auto while they are fleeing is a particularly cruel way to address the problem, as you're not making clean kills in this sort of situation.

We aren't talking about one or two pigs wandering into a backyard here. The sheer numbers are such that people who hunt them routinely end up shooting literally dozens of feral pigs in minutes, and it still isn't enough to keep the populations in check. Which is why USDA straight up says that "lethal techniques may be a more effective means for limiting population growth and achieving long-term suppression of damage".
