[Hawkeye (no spoilers)] Why a bow and arrow?

Hawkeye has the best aim of anyone in the world except maybe Bullseye. Why use a bow and arrow? Why not a gun? Is there any canon reason he picked a bow?

His gimmick isn't really the bow, it's the trick arrows.  If he had a sack full of trick bullets, he'd need ten different guns to fire them all.  With a bow and arrow, it's all the same stick, just a different head on it.  It reduces what he has to be proficient in by an enormous factor.
