I think GT is talking about the Collared Peccary also know as the Javalina! Here is a site for all kind of info on them. They only run around 30-60 pounds so a pistol would be good, but they run in packs and sport some really nasty tusks.Anything mean enough to eat prickly pear cactus is pretty immune to pain! lol I have hunted them a couple of times and in New Mexico you can usually also hunt quail at the same time and they do live in similar terrain. The wild pigs of the east are about 10 times as heavy and you really need more gun for them.
