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 -
Episode XX - Reading And Calculating Wind: Part III - Wind Number/B.C. Method
Use your bullets G1 B.C. to get your gun's wind number.
EX:
.308 - 175 SMK G1 B.C. - .505 = 5 MPH GUN
6.5C - 147 ELD-M G1 B.C. - .697 = 7 MPH GUN
In this episode, I explain the error with the bullet's "true B.C."
and how to correct that if it's needed. -

Using the clock method, Every 30 Minutes Is A 15º Angle:
12:00 - 0º - 0
12:30 - 15º - .25
1:00 - 30º - .50
1:30 - 45º - .70
2:00 - 60º - .86
2:30 - 75º - .96
3:00 - 90º - 1 -
Episode XVIII - Reading and Calculating Wind - Part 1 - Wind Angle
In this episode, we discuss how to get your wind angle and SIN. This will be used in our formula to calculate and dial our wind correction into our scope.

3:00 - 90º - 1
N - E = 0º - 90º
E - S = 90º - 0º
S - W = 0º - 90º
W -N = 90º - 0º -
Episode XVII - We're Back - Update/2 Formulas
Ranging Formula For Mils
Target size in inches x 27.77 / Target size in Mils
10" target measuring .5 Mils wide
10 x 27.77 / .5 Mils = 555.4 Yards
Click Value Formula
1/100 distance in yards / 2.777 x click
500 yards with .3 Mils = 3 clicks
5 x 2.777 / 3 = 5.4" -
