Young hobbits play bob-stones, which accounts for their accuracy.  But it doesn't account for the force that would be necessary to kill something large from a distance.<P>Of course, orcs in general are easy to kill, as seen by the fact that our heros kill hundreds yet receive hardly a wound in return.  Gamgee takes them out with pots and pans in Moria.  Even in Boromir's death scene he never actually took a blow.  It took three arrows while he was distracted fighting to fell him.  But a small rock thrown from 30 feet at kills instantly.  Go figure.
