Depends on placement more than anything. Your CNS, pump, or major tube gets taken out and you die no matter who you are. It just takes time, unlike in the movies. Anyone who's ever hunted can tell you that large mammals don't just fip over and die without a CNS hit.
Some sideways shooting retard that manages to miss any vital plumbing with 9 shots is just sad.
As to being shot not being effective against someone "who can take 9 at once":
"It happens so fast that you don't even get a chance to shoot back... I was scared the whole time... I was looking in the rear-view mirror like, 'Oh ****, somebody shot me in the face! It burns, burns, burns.'"
