At the Heym International Challenge in 2013 they had some really cool charging animal computer generated videos on a big screen. A double rifle had been fitted with a laser in one of the barrels and registered kill shots or not. If you killed it it dropped. If you didn't it killed you. An advantage was unlimited shots.

I dropped all the elephants and most of the buffalo with one or two shots, ie brain shots. But most of the lions got me, even when I went into spray and pray mode ie remember you could just pull the trigger multiple times.

Shows the difference in experience. Having shot buffalo and elephant, and having trained for the right bullet placement. Never hunted lion yet, I would have assumed the bullet placement was easier ... :O

A bit off topic but quite relevant. The shooting HAD to be quick. A bolt action would not have cut it at all.
