I'll bring up the point of terminal performance of a bullet from that range. No matter how accurate a shot is, there comes a distance that a bullet loses enough energy to ethically perform. So beyond the whole accuracy thing, there's the compounded effect of, or rather lack of effect, of the bullet. Never mind the trouble of combining a high BC design and one designed for terminal performance on game.
Even a 338 Lapua like cartridge will essentially be like a 357 magnum around 1000 yards. Just fine if we can place our shot right in the boiler room, but that boiler room of even a large elk shrinks down to about 1 moa from this ultra long range. I know people can shoot those kind of groups, but that happens after adjusting for things only known after test shots! Long range accuracy, at best, is a process. The best sniper with the best training still needs actual real time dope to make a reliable shot at that kind of range. If someone says they can set up, spot the wind, adjust the dope perfectly before the first shot, and hit from a cold bore within 1 MOA of a 1000 yard target with better than 30% odds, I call BS. And until someone can, a gut shot elk with a 357 mag is just as likely as one dropped right there.
Does anyone think a gut shot elk with a 357, without reliable means of immediately tracking it (because you're probably over an hour away), is ethical?
The only way I could see an ethical shot over 1000 yards is with a very powerful cartridge and true adjustments made by a series of shots on a dummy target, before the shot on the game is attempted. This is what the folks in the video did, but after attempting a shot on the elk.
