How is wind drift calculated for rifle shooting?

Wind drift equals wind speed × (time of flight − time of flight in vacuum). A 10 mph full-value crosswind on a .308 Win bullet at 500 m produces approximately 35–45 cm of drift, requiring 6–8 MoA of windage correction.

What is a wind clock in shooting terminology?

The wind clock expresses wind direction as a clock position relative to the shooter. 12 o'clock (head-on) and 6 o'clock (tail) are zero-drift positions. 3 and 9 o'clock are full-value winds; 1, 2, 4, 5, 7, 8, 10, 11 o'clock are partial-value winds.
