There is a lot of controversy about which part of the wind is most important, whether the greater angular dispersion at the muzzle will affect bullet flight more than wind at the target, which is now working on a slower moving bullet. . . no one of authority can seem to agree.
[/ QUOTE ]The wind closest to the shooter is the most important. All the coaches on long range rifle teams around the world know that. Other top competitors at long range know that, too. Some long range hunters know this: see below:
It's easy to see what wind has the most effect by using ballistic software showing wind drift, plotting the wind drift curve as a graph, then laying a straight edge tangent to any point on that drift curve. It's then easy to see there's about three times as much wind drift distance caused by a given wind across only the first third of the bullet's flight as there is for only the last third.
