Make a good shot on them. You have probably heard about the armour plate they have. It is a shield of fat that is really hard to penetrate. f you hit them to far forward you will hit this, and most likely just wound it. Like others said they are pretty agressive animals. On a trip to Texas i was charged by two and had to run and jump in the back of the jeep. So be careful and have fun, they are a blast to hunt.
