Pigs are a major problem around my neck of the woods. Fortunately I don't have any, or just haven't seen them. I am sure one passes through every now and then. They can be dangerous too. Especially if they think you are threatening their young. I have a couple of pig stories here.
Two years ago a friend and I were deer hunting on my ranch in North Texas. I had a shot on a deer relatively close to the fence line. I wounded the deer and it ran off and jumped the fence. I knew she wouldn't get far, so we took off tracking it. I have an agreement with the neighbor that if a wounded animal crosses the property lines, we will let each other do whatever it takes to make sure it doesn't suffer, or cause any other problems. We were about 50 yards on the other side of the fence tracking the deer into a thicket of trees. Enter the pig. I swear it was a freakin cow. This sow comes charging out of the thicket about 20 yards in front of us. My friend had his .30-30 up and ready to fire, and I had my .25-06 ready to go. Not an ideal weapon for such close range with the scope and all. She stopped about 10 yards from us and turned and ran. At this time, about 15 piglets ran parallel and away from us. They could not have been a week old.
Story two. My cousin and I were walking down a mostly dry creek bed. I was around 16 at the time, armed with a .223, my cousin armed with a lever action .45-70. We see a boar hog laying in the mud about 30 yards ahead. The boar stands up broadside to us, my cousin shoots him broadside with the .45-70. The hog rolls from the bullet impact, stands up, shakes his head, turns to us and charges. My quick thinking cousin fires another round at the charging hog hitting him in the head, killing him.
Not only are wild hogs destructive to property, but can also be dangerous if cornered or spooked.
