I would never do it on purpose, but I wonder how many of those shot from helicopters are maimed and gut shot etc...
Good point.
I imagine most hog hunters have gut shot some runners after dumping hog #1 in a group, but at least they're trying to make kills and will likely put another round in a wounded pig if they can.
I think most folks would say there's a difference when somebody is intentionally gut-shooting every animal to let them run away so they don't have to deal with them on-site. Probably not much difference to the pig though!
