A large number of those "missed" animals would have been wounded by fragments, maybe lost an eye, etc. This was disgusting in the highest sense and there is not even an inkling of shot placement being considered here. Just a complete idiot lobbing projectiles at wildlife for thrills, and doing a very poor job of it. Imagine how long it would take to get to a wounded animal, as 90% of them likely would be when hit? Not that he'd care, he'd just let them suffer and keep lobbing bullets til one fell close to the bait.
