Did he take into account the coriolis effect though?This was my question too. I have only shot that far a handful of times, but when I did I was not able to effectively spot my own impact, even when laying prone with a bipod and rear bag. Shooting across a canyon like that, the wind is likely to be doing different things in different places. And MOA at 1000 is what, 10.47 inches? No way I'm taking that shot on an animal.
