might have some effect on the sitting shooter, a greater
effect on the kneeling shooter, and a definite adverse
effect on the standing shooter. The effect of the wind on
your body can be decreased through the development of
the best possible shooting positions.
Wind Direction and Force
The direction of wind is explained by reference to
the face of a clock The firing line is thought of as the
center of a big clockface with 12 o'clock toward the
target butts and 6 o'clock to the rear. Wind blowing from
the right rear is a 4 o'clock wind (fig. 3-49).
Wind Reading Aids
Wind direction and force can be quickly determined
by observing the range flags. Figures 3-50 and 3-51 give
examples using the range flag. If no flag is visible, use
the following observations as a guide in determining
