I don't know that it was a low powder charge, but that could be one of the explanations. If a low charge was responsible, at 1K, the shot would have to be poorly executed for that theory to work, but still "lucky" enough to hit the vitals. We will never know that part. I do know that an oryx has very tough hide. The hide at the top of the neck under the mane is over 1" thick when caping the animals out.
I find it entirely plausible that a light for caliber bullet ran out of energy and was stopped by a large, flexible rib after penetrating some thick hide. We can accurately place bullets at extreme distances, but there is no guarantee what it will do when it arrives!

I agree. Shooting game at that distance is not an endeavor to be taken lightly...
My 6.5SAUM has a bigger boiler room, and I shoot 130VLDs @ 3200 out of it. But at 1K, even that larger bullet, with a higher b.c. & MV, doesn't really "pound" the steel. When I switch up & shoot my 140 JLK load (3070 fps), its easy to tell that it hits the steel a bit harder than the 130 @ 3200. On paper, its a ~150ft/lbs. energy difference (~950 for the 140, vs. ~800 for the 130). Just sayin' @ 1K, enough to tangibly differentiate the impact.
Nothing scientific to those comparison, of course. But after ya shoot steel for a while, and see how different bullet/cartridges impact at increased distance, ya kinda get an inkling as to how said bullet/cartridge might suffice for killin' stuff...
That said, I wonder how that dude's 100grTTSX/6/5-284 would ring steel? Bettin' it'd be on the weak soundin' side!
Sooo....
I ran a 100gr TTSX with w MV of 3200 thru my ballistic app. That speed should be doable from a 6.5-284?
Anyhoo...
the retained energy @ 1,000 yards is ONLY ~280 FT/LBS.
I sincerely doubt it'd be easy to find anyone who'd recommend that as adequate for taking a game animal???
Retired sniper, or not, if that dude did his ballistic homework, he'd seen how woefully inadequate his bullet/cartridge was at that distance...
On top of that, and with regard to the anatomy of the animal. It behooves the hunter to know his quarry!
Having no experience with African plains game, its all too easy for someone ignorant (like me) to correlate a plains animal to something more familiar. Like a whitetail, muley, elk, etc. I've skinned & butchered elk, and their hide is plenty thick enough!
If that oryx hide is even tougher, it becomes easy to deduce how that bullet did what it did, with such minimal retained energy at that distance.
And, all the more easy to put the blame onto the hunter for not factoring the animal's anatomical prowess into the equation...
Still, a crazy result & noteworthy opportunity to talk about this kinda stuff!
