Windage a
nd Moving Targets
The XLR reticle is highly effective when used for wind and moving 
target leads. Using the reticle for effective windage and moving target 
leads will require thorough knowledge of your cartridge’s ballistic 
performance under varying conditions as well as experience in reading 
wind strengths and target speeds. As in bullet drops, it is important 
for the shooter to learn a particular weapon’s windage/moving target 
corrections in MOAs rather than inches. Always hold the reticle into 
the wind.
Basic windage correction on center crosshair
When dialing elevation come ups, the center horizontal crosshair will 
be used for windage or moving lead corrections. MOA marks on the 
horizontal crosshair are graduated in 1 MOA increments out to 24 
MOAs, and at 1/2 MOA increments beyond that. 
3 MOA reticle windage correction for 400 yard shot in 10 mph crosswind 
using center crosshair. Elevation adjustment already dialed into riflescope.
