Hogs are a situation where semi-autos would be appropriate for hunts. When there is a pack of them, it is in the interest of the ecology to wipe them all out.
Although 5.56 might be enough for hogs.
The most expensive pork in the world comes from acorn fed hogs. If you can find a medium size sow or a shoat that's been feeding on acorns it will beat anything you can buy at Winn Dixie! A big boar's meat can be so rank the stink will run you out of the kitchen.
The old timers around here ran hogs pretty much on an open range basis. They would catch hogs every so often, earmark them and castrate most of the boars. The meat from the castrated boars is good.
When I was a kid I'd get invited to go when they "cut hogs". They wanted kids for speed and agility. We were expected to jump in with the hog dogs and hang on through the operation. It was a hoot, but I didn't have much good sense back then anyway, LOL. In exchange for our work we could go in and shoot a few hogs the rest of the year.
