He was using a 416! It was barrowed, as were his clothes (note the extra roomy fit?), since all of his luggage went astray. BTW, the rare example of a scope on an elephant rifle being more useful than tits on a bull.

Photos of the hunter, Anton, iirc, and Johnny Hulme standing next to the recovered tusks show their size. The tusks' proportions are so right that without a good reference they look either smaller or larger. Gonarhezhou elephants are very tall elephants as well. Johnny Hulme is not a small fellow, and that is a 500 he's handling like a toothpick!

BTW, the spine on my elephant in the photo was broken, whether by the shot that broke the ball joint or the subsequent shot that exited between the shoulder blades, who knows? But on the other elephant where I found the broken ball joint, it was not, and the tail's twitch and the leg circle signs of a brain shot began only with the insurance brain shot. And at that shot, the elephant fell from the upright to its side.
