Well ive had bullets blow 20' off, but it was over 1600 yds, and it was with a 200 gr bullet from a 30x378.
It would be one thing if it were a steady wind and you could adjust for it.
But otherwise you will never catch up with it at those distances, regardless of how good a shot you are.
Another thing that's very possible with wind at extreme distances, at least for hunters, is the very real possibility of the wrong animal falling over.
Shit happens they say, and especially when people are trying stupid stuff.
The spotter also needs to be the adult in the room, and determine when its time to pack it in.
