It probably depends on the territory. Here in central Texas I've seen a few that were probably over 200 Lbs., but mostly they are less than that. I'm sure there are some bigger ones, but we've been in drought conditions for the last two years and the food supply isn't what it might normally be.
As 09 bobcat says above, the hunting pressure is also a factor. There are some folks in the area where I hunt who run them with dogs and catch them alive. The hogs that weigh over 80 Lbs. can be sold -- they generally go to processors who package the meat for sale in Europe. Apparently France is a big consumer of "wild boar" meat. Actually, I kind of like it too. Just don't tell my in-laws I'm imitating the French!
