Buddy of mine killed an absolute monster bull on a big ranch with a guy videotaping. It is a great example of how much punishment they can absorb without stopping. At about 400 he underestimated the wind with his 300 magnum and hit it in the neck solidly but missed the spine. It ran a ways then stopped and took one right behind the front shoulder and drops. A short while later the bull stands up and starts to move away and takes 3 more in the chest at various angles before he stopped.
At least 4 fatal wounds but a riled up bull elk is not easy to put on the ground quickly - easy to see everything on a video replay - harder in the field at a distance in real time with adrenaline, recoil and muzzle blast to deal with while you assess your results.
