Being an old HP shooter & having spent many days spotting/scoring behind shooters, you can often see the curved trace of the bullet in the wind on the way to the target @ 600 & 1000 yards. It never goes back to a line perpendicular to the firing line. Not even if the farther flags downrange are drooping.The lateral trajectory of a bullet under the influence of wind will be a curve, not a straight line. If the influence of the wind stops at some point on the way to the intended target, the bullet will continue moving offline on the tangent line to that initial curve at whatever point the wind effect stopped. This is because of bullet rotation, the weathervane effect, and the resultant drag effect that are what actually cause the bullet to move offline under the influence of wind.
