Years back, a friend of mine got treed by a wild hog. He was hurting for money and thought killing a wild hog would be a good way to get some meat in the freezer. He went out with a .357 revolver, the only gun he owned, and six rounds of ammo...also all he owned. He nicked a boar on the first shot. It came after him and he sprayed the other 5 rounds without hitting it. He scrambled up a tree and spent the night there, sure that if he came down the hog would get him on the way to his car. He came straight to work the next day, looking like he'd slept in a tree. I bought him a couple family packs of ground meat so his kids could eat until payday and counseled him to leave the pigs alone.
