Most telescopic sights lack parallax compensation due to cost-benefit, as they can perform very acceptably without such refinement since most applications do not demand very high precision, so adding extra production cost for parallax compensation is not justified. For example, in most hunting situations, the "kill zone" on the game (where the vital organs are located) can be so forgivingly big that a shot hitting anywhere within the upper torso guarantees a successful kill. In these scopes, the manufacturers often design for a "parallax-free" distance that best suits their intended usage. Typical standard parallax-free distances for hunting telescopic sights are or as most sport hunting rarely exceed 300 yd/m. Some long-range target and "tactical-style" scopes without parallax compensation may be adjusted to be parallax-free at ranges up to 300 yd/m to make them better suited for the longer ranges. Telescopic sights used by rimfire guns, shotguns and muzzleloaders that are rarely fired beyond 100 yd/m ranges will have shorter parallax settings, commonly 50 yd/m for rimfire scopes and 100 yd/m for shotguns and muzzleloaders. However, due to parallax effect being more pronounced at close distances (as a result of foreshortening), scopes for airguns (which are commonly used at very short ranges) almost always have parallax compensation, frequently an adjustable objective design, which may adjust down to as near as .
