Those of you who have ever shot at the infamous Rattlesnake Mountain (Tri-Cities Shooting Facilities), in Benton WA, know what wind is like. I remember when I first started shooting FTR I shot quite a few LR matches out there and the prevailing wind would be 30-40 MPH. My biggest windage adjustment to date was 26 MOA between what I had dialed and what I was holding. This was way back when I was shooting 155.5gr Bergers. I just shot the Cold Bore Rifleman Team Challenge last weekend at Rattlesnake, and day two gave us a good taste of the typical Rattlesnake winds. I was still able to connect on the longest target of the match with a 2.75 Mil wind hold at 825 yards shooting my 6.5x47 and 123gr Scenars.
Stories and anecdotes aside. F-class matches are a great place to get wind experience since you have the luxury of wind flags downrange and each shot being marked. Tactical shooters can gain a lot just by going to f-class matches simply for the wind practice. It has helped me immensely in tactical shooting.
