I once shot three bulls out of a small herd in the Selous Game Reserve, in Tanzania. They were lined up facing me, rather than bunched up, but I shot all three in the middle of the chest. Two were one shot kills and the third appeared to be dead on his feet, because he was left standing looking in another direction, as the rest of the herd decamped. One more shot through the shoulder finished the job.

I was using my wildcat .505 SRE (570 grain FMJ bullet at 2150 fps., just like the .500 NE) and none of the bullets exited. I don't think I would have been comfortable trying those shots with a much smaller caliber. A .458 WM, yes, but anything less, no.

I was not shooting off of sticks, as I suspect the hunter in the film clip was. I don't believe in shooting off sticks at dangerous game.
