a friend on mine hunted some on the king ranch a few months ago. he is having the head mounted. I believe they like to hunt them from the back of jeeps there. he had a 300 win magnum and shot it several times, it still wasnt dead. His partner had to shoot it . 438 or . 458. or something of that size, point blank to kill it. These things weigh about 800 pounds or more, run as fast as horses and have very thick skin. He is trying to get me on a hunt at the King ranch with him. His main suggestion in choosing a gun is to buy or borrow the biggest you can find. He has hunted various big game and said these things are very hard to bring down.
They were brought into the area to be raised like cattle, but they couldne be controlled. The meat is similar to beef.
