The shooters use external signs, such as flags to detect wind travel and speed
..  Range finding is done with known reference points and range finders.  They
calculate the drop and adjust for hold over.  On the videos I watched the
crosshair was hardly on the target.  Instead, the crosshair would be2 or 3
mil dots high and a few to the left.  You would see the pellet fly down the
trajectory path to the target.
