If you think you don't use the barrel to shoot, and are an exceptional shot (as in uses full choke for everything exceptional,) consider this. Targets painted luminescent or glued with glow sticks slung out into a pitch black night. No lighting so you can't see the barrel. How well do you do?
I'm not good enough for my results to count but I think I'll try it anyway. Could be wrong, but I'm pretty sure everyone aims with the barrel even though it's best to not focus on it.
