Rifleman's rule is a "rule of thumb" that allows a rifleman to accurately fire a rifle that has been calibrated for horizontal targets at uphill or downhill targets. The rule says that only the horizontal range should be considered when adjusting a sight or performing hold-over in order to account for bullet drop.
In ranged weapons such as firearms and artillery pieces, the act of sighting in or sight-in is a preparatory or corrective calibration of the sights with the goal of having the projectile (e.g. bullet or shell) placed on a predictable impact position in relation to the sight picture.
A milliradian (SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). ). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or
For instance, after guessing the wind strength in meters per second (m/s), this wind value can be transferred to a sight correction in number of clicks. This rule of thumb applies to winds that come 90 degree from the side (full value), however winds coming from an angle must be taken into account by applying less sight adjustment.

The line of collimation or line of sight should coincide with axis of the telescope. [1] The line of sight should also be perpendicular to the horizontal axis at its intersection with the vertical axis . Also, the optical axis, the axis of the objective slide, and the line of sight should coincide. Adjustment of horizontal plate levels.
Line-of-sight fire, shooting directly at a visible target on a relatively flat trajectory. The target is in the line of sight of the sighting device and the rifleman's rule applies. Line-of-sight range; Line-of-sight (missile), the straight line between the missile and the target; Radar horizon
