In South Africa, we had a name for hunters like this - we called them "kitty food"...
Seriously, there are all too many documented cases of lions being hit up to ten times by major-caliber rounds, that performed exactly as their manufacturers intended, and still taking several pounds of hamburger off some hunter's favorite posterior. They are really tough animals, and in a charge situation, with adrenaline flowing and the normal agressive instincts of the lion in hyperdrive, you're going to have to take out the brain or spine, or some major bone structure, to stop him reaching you. Once he's reached you, he's likely to die chewing on your favorite body.
There have been all too many professional hunters killed by lion, who did everything right, shot the lion repeatedly with hits that ultimately proved fatal, but still got chomped because the lion didn't know he was dead. That's what dangerous game hunting is all about, although this idiot doesn't seem to have realized it... And, by the way, a .458 is NOT a superior lion round, particularly in a deep-penetrating round like that described here. It won't have enough expansion to make a bigger hole and break bone and blood vessels as well as will a softer-point, better-expanding round. It's also a case of overkill, in that it will probably penetrate right through the critter and expend most of its energy on African dirt on the other side. Rather choose a bullet that will stay in the body and expend all those foot-pounds of energy where they'll do the most good (or harm, depending on your point of view!).
