I created a wind profile where just the 1000 yard flag picks up from 10 mph to 20mph. No other changes but the moa needed doesn't change. Would this be correct?
Correct, there is no drift from a 10 mph gust of wind occuring at the exact time of bullet impact on the target. The wind needs time and distance to move the bullet. Defletion would impact say an 1100 yd flag.
