Supposedly the shot was taken from 200 yards away.
In my nonprofessional opinion, that is crappy aim. I can hit an apple from 100 yards away, with a black powder rifle, with an unriffled bore, with iron sights, standing up, repeatedly. I would expect a modern rifle with a riffled bore and a scope and a larger target to be much more accurate from a prone position.
Everyone is underestimating how hard it is to willingly kill a person. Shooting a paper target or apple at a range is nothing like sighting on a person, letting out your breath and pulling a trigger.
