So when you skinned the critter out, assuming you might have, where did the first shot go?
Reason I ask, the shot you suggest, quartering to at 15 degrees, places the "shield" a thick growth of gristle that covers the shoulder of wild boar boars, and the shoulder blade at such an angle that it might help to deflect the round. The fact that he stopped and charged at 200 yards, tells me he was hit pretty good to stop. But not necessarily a killing lung shot, if he charged.
Otherwise... yeah they are that tough!
