Sea level air pressure is 14.7 PSI, IIRC. Calculate your square inches of bore and multiply that decimal my 14.7 to see how little the air pressure will push the bullet. Only the most poorly-loaded ammo will have bullet creep in a vacuum (at least until it all leaks out--except for waterproof stuff).
There's a sentry removal tactic using underwater firing, but I prefer to not publish it. I think of maritime cups as being not so much for something hitting the fan, but for when I want the stuff to hit someone else's fan.
