Revisiting this thread AGAIN - I shot a Pro Series PRS match last weekend here in Kansas, during which we saw gusts up over 40mph, some gusts up over 50. My highest wind hold for the day was 6.1 mils at 1040yrds, shooting in a prevailing 28mph wind at my 2:30 - which is 19 feet of WIND drift. Every 2mph wind bracket was halfway across the plate, and most of our 30sec wind captures were seeing 10-12mph variability in wind speed. It was brutal.
