how much of a forgetup do you have to be to miss your brain
not much. if you think about it, it makes some sense that you could survive for a small amount of time after the first shot
remember, a bullet isn't an explosive; it'll destroy one part of your brain extensively, but that doesn't necessarily mean other parts of the brain will be destroyed alongside it (at least not instantly). you do, however, have the dubious "advatange" of the bullet breaking up within your body (esp. after the skull), which should do more wide-reaching damage.
