I see a Grizzly bear defense thread about every month and I've never seen a feral hog defense discussion.
So here it is and it's dedicated to everyone in Texas who has never even seen a grizz except maybe mounted in Cabelas.
My feral hog defense would be 9mm and lots of it cause evidently it will be more than one if you have to deal with them, like zombies.
They're also smarter than bears so they probably have some sort of command structure.
