I am taking it for granted that the wound I believe I see is the entry wound which is high on the shoulder. Where should that shot been placed? It looks like a good lung shot to me. But then I do not know hog anatomy.

That is one large hog. And a heck of a set of tusks it looks like. It will be interesting to learn his weight. Congratulations on harvesting such a great hog as that. That really is something.
