What type of wind direction is referred to as Full Value wind?

Full Value wind refers specifically to wind that comes directly from the 3 o'clock or 9 o'clock positions relative to the shooter. This is significant because such winds have a direct impact on the flight path of the projectile, causing drift to the left or right, depending on the direction of the wind. Understanding Full Value wind is crucial for marksmanship, as it requires the shooter to account for horizontal movement in their aim to maintain accuracy on target.

In contrast, a wind from the 12 o'clock position would affect elevation more than horizontal trajectory, while a wind blowing directly away from the firer does not pose a lateral challenge. Winds with variable directions introduce inconsistencies that make it difficult to predict their effects on shooting, but do not represent the consistent lateral drift that Full Value winds create. Thus, accurately identifying Full Value wind is essential for effective shooting techniques.
