Most of the time people miss judge hogs thinking that they are bigger than they are. Most wild hogs have a bigger frame than what they will weigh. a lot of people will say that pig is 250Lbs and in reality it will go 175Lbs. The only chance you have is looking at a lot of pigs and watching them get weighed to give you an idea. pictures can lie and you can make hogs look bigger than they are.
Good Luck let us know how you do.
