Trajectory, Windage and Drift Again
When shooting in closed ranges the trajectory and drift and the action of the wind on the bullet, described in the last chapter, need not be taken into consideration for the following reasons: (1) because the range is not long enough to produce a curved trajectory; (2) the drift.in so short a distance is scarcely noticeable, and (3) there is little or no wind.
If you are shooting a .22-caliber rifle you need not bother overmuch about these things, for the range is too short; but for long-range shooting these three factors are very important and especially if you are shooting a large-caliber gun. The way to overcome these deviations of the bullet from a straight line is to use sights which are made so that you can allow for them.
