I'm not buying it. If the gun was directly pressed on his skull there would be significant kickback of the gun from the gas build up. Think Daffy Duck sticking his finger in Elmer Fudd's shotgun. I think it would way messier. And then the shooter would be taller towering over PM.
And again how did the buckshot exit the room and go into the tree behind the feed room.
