Stopping Sight Distance
A rule is used to measure a distance.
The steppe was quite a sight even in a distance!
:parallax error occurs when the line of sight or measure is not at right angles ( perpendicular ) to the objects being measured. Any distance between the object and the measuring reference ( for example a rule ) will cause a misreading. This error will increase as the distance between the object and the reference increases.
An indicated distance, usually within sight.

One "Click" is not a measurement of distance; it is a rifle sight adjustment. By moving the trajectory or elevation adjustments of the rear sight of the M1 or M16, the sight picture is moved by one inch at twenty-five meters, right or left, up or down.One "Klick" is military shorthand for the distance of one kilometer.
100 yards is the most effective distance to sight in primarily. However, if you know the distance your rifle will be performing at, then sight in as close to that as you can. For instance, if you are going to be hunting open land i.e Wyoming, then youll most likely want to be set in at 200 considering typically, you will be shooting longer distances. For regular white tail hunting, 100 yards is perfect.
