Basic windage correction using drop line on reticle
When using the reticle for elevation correction rather than dialing, the
windage dots will be used for windage and moving lead corrections.
The windage dots are graduated in 1 MOA increments and provide
increasingly greater span in the lower part of reticle, corresponding
to the need for greater windage correction at longer distances. The
supplied windage dots will accommodate crosswinds up to 20 mph for
most popular high-powered applications. Remember to hold the reticle
into the wind
14 MOA reticle windage correction for 20 mph wind at 800 yards using
the 26 MOA reticle drop line.
Example
20 mph wind
Full value wind at 90 degrees
