This video is about Reading wind at Max ord or at you? 

We teach Max Ord wind reading in class, see the results at 1547 yards
We had to change ammo lot after trying 2 boxes the vertical was all over, about. 1 foot spread ( un except-able) left and right wind was perfect every shot though. Once we changed ammo lots and trued velocities. 2 moa off by the way!
We let the suppressor cool to see the target and you see in the video 1 st 2nd and 3 rd round impacts between the plate a clay! Great ammo this time! Our wind is easy to learn. But hard to see sometimes.
