I'm speaking from a position of almost total ignorance here, but surely a bullet is travelling 2 or 3 times faster than sound? Over the short distances involved is it really possible to do this? I would have thought a light or electric trigger would be better. e.g. fit the trigger or the hammer of the gun with an electrical gizmo to fire the flash. -- Cheers, Bob
