Episode XXI - Reading and Calculating Wind: Part 4 - The Formula

1. Determine the wind speed.

2. Divide the wind speed by the Q.W. number.

3. Multiply the Q.W. dope by the quotient.

4. Determine the SIN of your wind angle.

5. multiply the product by the SIN of the wind angle.

EX.1 - 600 yards, with a 12 mph wind from 1:00 with a 4 mph gun

1. 12 MPH wind

2. 12 / 4 = 3

3. .6 x 3 = 1.8 Mils

4. 1:00 = .5 sin

5. 1.8 x .5 = .9 Mils to adjust for the wind

EX.2 - 600 yards with a 12 mph wind from 1:30

1. 12 mph

2. 12 / 4 = 3

3. .6 x 3 = 1.8 Mils

4. 1:30 = .7 SIN

5. 1.8 x .7 = 1.26 Mils to adjust for the wind

EX.3 - 700 yards, 15 mph wind from 2:00

1. 15 x 7 = 2.14

2. .7 x 2.14 = 1.49 Mils

3. 1.49 x .86 = 1.28 Mils
