Although they are still a pig they are much leaner and more complex to smoke, especially legs. I just noticed your post and you probably already started, plenty of info online I’m sure. Brining (many brine recipes on line for pork), injecting I’ve used apple cider cut with 1/4 water but many other ways, you have to start slower cooking longer to break down the collagen in wild hogs. Spray with water or apple cider mixed with water every hour or so. Cook a few hours under 200 then stay under 225 a few hours. After about 6 hours I would wrap tightly in foil and cook at 225 until 195-200. Don’t go over the 200 it’ll be too soft. Good luck on the cook, hopefully it’ll all work out for your son and his college buddies.
We start hunting them in January after Deer season is over and stop by March. We don’t fool with them in warmer weather the meat spoils quickly. We usually will cook a couple whole hog on a pit but mainly we get them processed in sausage. We don’t take many but we only shoot sows to eat. We’ll shoot some for local food shelters.
