That's not hunting at all. It's an excercise in markmanship.
BS.
I mean, is there some magical range at which it becomes shooting rather than hunting?
There are the muzzleloader/.45-70/.30-30 crowd that says anything over some arbitrary range is unethical and more shooting than hunting. Then there is the .30-06 crowd that says anything over some other longer arbitrary distance is unethical and is more shooting than hunting. Then there is the magnum crowd with their own arbitrary and highly theoritical maximum engagement distance.
Then there is me. I am just sick of hearing people extrapolate their own capabilities and ethics on others. The maximum ethical range a hunter should be engaging game is almost entirely individual. It depends on the skill of the hunter, his/her equipment, and the environmental/external circumstances at the time.
I'm not shooting at a game animal outside 400 yards with my 7 Mag, but that is a reflection of my own abilities and, to a lesser extent, the capabilities of my equipment. But I am not about to say anyone who dedicates the time to developing the skills, spends the time scouting, then glassing, and then ranging and setting up the shot isn't every bit the hunter that some hillbilly with a lever action tromping through the woods is.
And BTW, I am almost positive most of the work seen done in that movie is done with a 168 gr Berger VLD in a 7mm Rem Mag.
