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.

Methods Of Estimating Distances By The Eye
1. Decide that the object cannot be more than a certain distance away,
or less than a certain distance. Keep the estimate within the closest
possible limits and take the mean of the two estimates as the range. For
instance, that dee...

completed. No distance used in this test will be less than 547 yards
(battle sight range) or more than 1200 yards, which is considered the
extreme range for eff...
Estimating Distances By Sound
Sound travels at the rate of about 366 yards a second. Therefore,
multiply the number of seconds intervening between the flash of the gun
and the report of the same by 366, and the product will be the distance
in yards to the gun.
General rule for changing the elevation after hitting the target: A
change of elevation either up or down, of 100 yards on your rear sight,
will raise or lower your bullet in inches on the target equal to the
square of your distance...
