What mechanism can I use to make Lego technic rubberband gun fire without it having to reload after every shot?

Its pretty simple after an hour or so of fiddling with lego technic to make a working gun, but how can i make it not have to reload after every shot?

Websearch for the commercial repeating rubberband guns (up to and including the rubberband gatling gun), adapt their designs.... Basically, it's a matter of using an escapement mechanism to allow a wheel to advance one step each time the trigger is fired, releasing only one of several rubber bands preloaded onto it. I don't know whether Lego would hold together under that much stress, though; beware of your gun imploding unexpectedly.
