Altitude or height (sometimes known as depth) is defined based on the context in which it is used (aviation, geometry, geographical survey, sport, atmospheric pressure, and many more).
Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth (or that of another planet).
A backpack — also called bookbag, kitbag, knapsack, rucksack, rucksac, pack, sackpack or backsack — is, in its simplest form, a cloth sack carried on one's back and secured with two straps that go over the shoulders, but there can be variations to this basic design.
In ballistics, the ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight.
Ballistics is the field of mechanics that deals with the launching, flight, behavior, and effects of projectiles, especially bullets, unguided bombs, rockets, or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.
The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land.
Benchrest shooting is a shooting sport in which very accurate and precise rifles are shot at paper targets.
A bipod is an attachment, usually to a weapon, that helps support and steady it.
A bullet is a kinetic projectile and the component of firearm ammunition that is expelled from the gun barrel during shooting.
In guns, particularly firearms, caliber or calibre is the approximate internal diameter of the gun barrel, or the diameter of the projectile it shoots.
A cartridge is a type of firearm ammunition packaging a projectile (bullet, shots or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device (primer) within a metallic, paper or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting.
In physics, the Coriolis force is an inertial force that acts on objects that are in motion relative to a rotating reference frame.
Cosine similarity is a measure of similarity between two non-zero vectors of an inner product space that measures the cosine of the angle between them.
In optics, the exit pupil is a virtual aperture in an optical system.
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight.
The field of view is the extent of the observable world that is seen at any given moment.
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.
High Power Rifle, also called XTC from "Across the Course", is a shooting sport using fullbore target rifles which is arranged in the United States by the National Rifle Association of America.
Humidity is the amount of water vapor present in the air.
An intermediate cartridge is a rifle/carbine cartridge that is less powerful than typical full-power battle rifle cartridges (such as the.303 British, 7.62×54mmR, 7.92×57mm Mauser,.30-06 Springfield or 7.62×51mm NATO), but still has significantly longer effective range than pistol/personal defense weapon cartridges.
The International Confederation of Fullbore Rifle Associations (ICFRA) is the international association for the fullbore target rifle shooting sports of Palma and F-Class, which are long range competitions shot at distances between 300 and 900 meters or 300 to 1,000 yards depending on the range.
A laser rangefinder is a rangefinder that uses a laser beam to determine the distance to an object.
The metre (British spelling and BIPM spelling) or meter (American spelling) (from the French unit mètre, from the Greek noun μέτρον, "measure") is the base unit of length in some metric systems, including the International System of Units (SI).
Metre per second (American English: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.
Miles per hour (abbreviated mph, MPH or mi/h) is an imperial and United States customary unit of speed expressing the number of statute miles covered in one hour.
A milliradian, often called a mil or mrad, is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian).
A minute of arc, arcminute (arcmin), arc minute, or minute arc is a unit of angular measurement equal to of one degree.
A mirage is a naturally occurring optical phenomenon in which light rays bend to produce a displaced image of distant objects or the sky.
Muzzle velocity is the speed of a projectile at the moment it leaves the muzzle of a gun.
A rifle is a portable long-barrelled firearm designed for precision shooting, to be held with both hands and braced against the shoulder for stability during firing, and with a barrel that has a helical pattern of grooves ("rifling") cut into the bore walls.
The English phrase rule of thumb refers to a principle with broad application that is not intended to be strictly accurate or reliable for every situation.
A shooting range or firing range or archery range or pistol range or rifle range or shooting gallery or shooting ground is a specialized facility designed for archery or firearms practice.
Shooting sports is a collective group of competitive and recreational sporting activities involving proficiency tests of accuracy, precision and speed in using various types of ranged weapons, mainly referring to man-portable guns (firearms and airguns, in forms such as handguns, rifles and shotguns) and bows/crossbows.
Spindrift is a weather effect.
Steel targets are shooting targets for firearms made out of hardened (martensitic) steel, and are used in sports such as cowboy action shooting, practical/dynamic shooting and for long range shooting, as well as recreational plinking.
A telescopic sight, commonly called a scope, is an optical sighting device that is based on a refracting telescope.
Temperature is a physical quantity expressing hot and cold.
Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface.
Transmittance of the surface of a material is its effectiveness in transmitting radiant energy.
A weather vane, wind vane, or weathercock is an instrument for showing the direction of the wind.
Wind is the flow of gases on a large scale.
The yard (abbreviation: yd) is an English unit of length, in both the British imperial and US customary systems of measurement, that comprises 3 feet or 36 inches.
The.22 Long Rifle (metric designation: 5.6×15mmR) cartridge is a long-established variety of.22 caliber rimfire ammunition, and in terms of units sold is still by far the most common ammunition in the world today.
The.223 Remington (.223 Rem) is a rifle cartridge.
The.308 Winchester (pronounced: "three-oh-eight") is a rimless, bottlenecked rifle cartridge and is the commercial cartridge from which the 7.62×51mm NATO round was derived.
