I have often said that at some point simple physics obviates the best shooting in the world. This guy used a 6.5 Creed shooting 147 ELDM factory loads? So let's say his rifle shoots 1/2 MOA. That means at 1507 his bullet dispersion is 7.5" to start. The wind was blowing 6 mph? What if it was 5 or 7? An error of only one mph results in a +/- 1.3 MOA, which means even if he fired one hole groups at 1507, an error in wind estimation of .25 mph blows EVERY bullet out of the 10" vital area. By the way, the total wind drift would be 9 MOA, or over 11 feet!
I made a video some months ago holding my Kestrel in the wind. I recorded almost a minute of data, then played it back frame by frame and entered the wind speeds in an Excel file. I don't have that file handy, but IIRC the average wind speed was about 6 mph. There were very few frames where the wind stayed the same. At 1507 your TOF is 2.8 seconds - you are telling me this guy made a perfect wind call and it didn't change at all for nearly 3 seconds?
I won't inject ethics; I am simply pointing out some easy mathematical facts. This guy got lucky; there is no other way to spin it.
