Looked in the archives for this but came up dry. I've heard it said that wind conditions at the muzzle are more important than during time of flight or at the target. That doesn't make sense. When a projectile leaves the muzzle it is travelling it's fastest in open air. Why wouldn't wind deflection further downrange have the greater affect? Last Summer I set-up targets at 1, 2, 3 and 400 yards with surveyors tape flags at each distance. What a learning experience. Numerous times the 100yd flag was blowing one way, the 200yd flag was opposite and the wind leapfrogged like that out to 400. Or while chuck hunting, it's blowing at the shooter position but not at the chuck. I understand the wind is important, just need more input. Thanx.
