I have a simple question about windage. Say I am shooting at 400 yards, and my chart says I need 1.5 MOA of adjustment for a 5 MPH wind. What if the wind is at 15 MPH? Do I use 4.5 MOA adjustment? I guess I am asking if the necessairy wind adjustment increases at a steady rate, like a 1mph wind moves the bullet a certain distance, then a 10 mph wind will move it ten times as much?
