This target is used during slow fire at 500 and 600 yards.
RAPID FIRE TARGET
This target is always used with the battle sight at 200, 300, and 500 yards rapid fire. Battle sight is the position of the rear sight when the leaf is laid down, which is the habitual position of the rear sight leaf at drill. It is an open sight, and corresponds to an elevation of 547 yards.
WINDAGE
The rear sight is set on a movable base so that it can be moved to the right or left and the aiming point shifted accordingly in order to counteract the effect of the wind on the bullet.
General Rule. To shift the striking point of the bullet to the left move the rear sight to the left. And, of course, the reverse holds true when it is moved to the right.
A Specific Rule. One point of windage moves the striking point of the bullet 4 inches for every 100 yards you are distant from the target. (One point of windage at 200 yards causes the bullet to strike 8 inches to the right or left of the line of aim; one point at 300 yards causes a 12-inch deflection of the bullet; one point at 500 yards a 20-inch deflection, and so on.)
