Re: wind doping
R X V / Constant = Correction
That's assuming full value wind.
Range is in 100 yards, 6=600, 7=700 etc.
V is wind velocity
The constant is for your load.
Example I shoot 168s at 2550 fps my constant would be 10
Lets say a 20 MPH wind at 6oo yards with my M1A and 168s
6 X 20 = 120
120 / 10 = 12 so I would correct for 12 MOA
You have to find the constant for your ammo specs.
