A. See Fig. 70.
Q. What is one point on the deflection-scale equal to at the target?
A. One five-hundredth of the range in yards; thus one point equals 2 yards at 1000 yards, 4 yards at 2000 yards, and so on.
Q. Example: The range is 5000 yards, and the drift for that range is found in the range-table to be 12 minutes; how would you set your deflection-scale on the telescopic sight?
A. "Fire left" 12 minutes, or 4 points.
Q. Why?
A. Because drift in our service is always to the right, and to overcome this drift and make the projectile hit the target we will have to fire to the left this 12 minutes due to drift.
Q. Example: The range is 5000 yards, and the component of the wind perpendicular to the line of fire is 20 miles, giving from the range-table correction for drift equal to 12 minutes and wind 6 minutes. The wind is blowing from right to left. How would you set your sight?
A. "Fire left" 6 minutes.
