The field of non lethal and limited range weapons engineering, as opposed to combat weapons, is still not sufficiently explored. These types of weapons can be used by security forces to carry out their fire missions usually demanding high accuracy firing. Projectile ballistic coefficient dispersion can essentially affect nominal characteristics of non lethal and limited range weapons. The influence of projectile ballistic coefficient dispersion on projectile target affecting parameters is researched in the article. Common dependencies and methods of external ballistics are applied. The way to determine maximal and minimal usage range declining due to projectile ballistic coefficient dispersion is defined. The results represented in the article can be used for the purpose of non lethal and limited range weapons designing and projectile ballistic coefficient demands creating.
