Feral Hog Hunting in SE Texas / Bullet weight for hog hunting?

Do some research. Feral hogs are a big problem in Texas right now. I am from the Dallas/Fort Worth area and I know some hunters who don't have too many problems in finding farmers and ranchers who need some hogs removed. I know that there were some hog problems in Galveston back in the 90's. Pelican Island had feral hogs. That may be taken care of by now though. I would start by checking with some gun shops. A lot of them have information on things like this. They would definately be able to tell you what kind of weapon to use. I think that a .30-06 would do the job but it might be overkill. However, I have never hunted hogs myself so I would not know. It is best to find a person who has done this type of hunting.
