The video linked to by the OP is now 'Private' and can't be viewed. That said, I don't need to see it to have an opinion about 900 yard head shots on elk.
While I would have no problem with someone taking such a shot at an enemy combatant, I can't think of any reasonable justification for taking one at a game animal. At 900 yards time is on the hunter's side and patience will produce a higher percentage shot opportunity virtually every time.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
