Crosswind Data
The best reaction to a stiff crosswind is to shift your location so you're either perfectly
upwind or downwind from your target and thereby eliminate the effect of wind altogether.
When relocating is physically or tactically unfeasible, the Wind Data in this Table allows
great accuracy when properly applied.
And don't forget that unlike a moving target, an oblique wind is NOT 1/2 value but 3/4
value since a bullet is sensative to a crosswind.
