I agree mostly, but I'd qualify that--I don't car how long another guy shoots, provided he can make the shot.
But going back to the title of the thread, hitting a stationary target that size at that distance is different than hitting an animal's head, which is the part of its body most likely to move.
To put it another way, if you can hit an elk head-sized target at that distance, you sure as hell can hit its vitals. So why not just do that.
Either he was aiming at the chest and hit it in the head but didn't recover it and chose to represent it as a head shot on an internet video, or he was aiming at the head and missed.
