In Alabama we have ferral hogs mostly Russian Black boar. They can be pretty testy and big. I got a 350 pounder a few years ago at 150 yards in the swampy bog from a tree stand. I had to shoot left handed but I practice left and right with all my guns. One shot in below the ear with my 270. I have dropped some closer that got back up and had to shoot them again. I aint about to go after one with a spear. No closed season and no limit on them.
I'm in Oklahoma on the Red River,the hogs are thick and terribly destructive.It's common to see 20 - 30 in a bunch.Even our Biologists and Wardens will tell you that if you can't pack 'em out to just kill 'em and leave 'em,they're such a problem.
