This is not an accurate statement. Wind at the target has more effect on a bullet than wind closer to the rifle's muzzle. As the bullet flies, it loses speed and is more susceptible to bullet drift closer to the target where it has less speed to cut through the wind.
If I am reading that graph right the green line is for a wind acting from 0 to 333 yards and then stops, the red line is with the wind starting at 667 and stopping at 1000 yards.
He means the overall effect, not that the bullet is moved further when it is closer to the muzzle.A given crosswind speed close to the rifle has more effect on downrange bullet drift than that same crosswind near the target.
Much better than I put it as well.lysander, thanks for putting the icing on my drifty cake. Yes, your interpretation was better written than my explanation.
not to mention the fact that going offline early is magnified more and more as it moves away from that spot.
