I've shot SF 600 yd in gusts so strong they would blow the rifle (tight sling and all) all the way off of the bull.
Offhand-style shooting technique comes into play. Fast squeeze when the sight settles under the bull. Dry fire to not learn/unlearn flinch.
But you also have to pay attention to the wind during an RF string. I've gone from 3 MOA one side, to two after the reload, and to two the other way at about shot #7, because of changing winds.
IIRC, the wind at the line has more effect than at the last 100 yards in front of the pits.
