A shotgun is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which discharges numerous small spherical projectiles called shot, or a single solid projectile called a slug. Shotguns are most commonly used as smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting sabot slugs are also available.
Shooting is the act or process of discharging a projectile from a ranged weapon. Even the acts of launching flame, artillery, darts, harpoons, grenades, surgerys, and guided missiles can be considered acts of shooting. When using a firearm, the act of shooting is often called firing as it involves initiating a combustion (deflagration) of chemical propellants.
Shooting sports is a group of competitive and recreational sporting activities involving proficiency tests of accuracy, precision and speed in shooting — the art of using ranged weapons, mainly small arms and bows/crossbows.
An air gun or airgun is a gun that uses energy from compressed air or other gases that are mechanically pressurized and then released to propel and accelerate projectiles, similar to the principle of the primitive blowgun. This is in contrast to a firearm, which shoots projectiles using energy generated via exothermic combustion (deflagration) of chemical propellants, most often black powder or smokeless powder.
The .50 BMG, also known as 12.7×99mm NATO, and designated as the 50 Browning by the C.I.P., is a .50 in (12.7 mm) caliber cartridge developed for the M2 Browning heavy machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard service cartridge for NATO forces, as well as many non-NATO countries. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber rounds. The rounds intended for machine guns are made into a continuous ammunition belt using metallic links.
Plinking refers to informal target shooting done for leisure, typically at non-standard targets such as tin cans, logs, bottles, balloons, fruits or any other man-made or naturally occurring objects. The term is an onomatopoeia of the sharp, ringing sound that a projectile makes when hitting a metallic target such as a tin can or a road sign plate.
The .22 Long Rifle, also known as the .22LR or 5.6×15mmR, is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of firearms including rifles, pistols, revolvers, and submachine guns.
In the United States (U.S.), a marksmanship badge is a U.S. military badge or a civilian badge which is awarded to personnel upon successful completion of a weapons qualification course or high achievement in an official marksmanship competition. The U.S. Army and the U.S. Marine Corps are the only military services that award marksmanship qualification badges. However, marksmanship medals and/or marksmanship ribbons are awarded by the U.S. Navy, U.S. Coast Guard, and U.S. Air Force for weapons qualifications. For non-military personnel, different U.S. law enforcement organizations and the National Rifle Association (NRA) award marksmanship qualification badges to those involved in law enforcement. Additionally, the Civilian Marksmanship Program (CMP) and the NRA award marksmanship qualification badges to U.S. civilians. Most of these organizations and the U.S. National Guard award marksmanship competition badges to the people they support who succeed in official competitions.
A shooting range, firing range, gun range or shooting ground is a specialized facility, venue, or field designed specifically for firearm usage qualifications, training, practice, or competitions. Some shooting ranges are operated by military or law enforcement agencies, though the majority of ranges are privately owned by civilians and sporting clubs and cater mostly to recreational shooters. Each facility is typically overseen by one or more supervisory personnel, known as a Range Officer (RO), or sometimes a range master in the United States. Supervisory personnel are responsible for ensuring that all safety rules and relevant laws are followed at all times.
A milliradian 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. Milliradians are also used for comparing shot groupings, or to compare the difficulty of hitting different sized shooting targets at different distances. When using a scope with both mrad adjustment and a reticle with mrad markings, the shooter can use the reticle as a ruler to count the number of mrads a shot was off-target, which directly translates to the sight adjustment needed to hit the target with a follow-up shot. Optics with mrad markings in the reticle can also be used to make a range estimation of a known size target, or vice versa, to determine a target size if the distance is known, a practice called "milling".
In military and police contexts, a warning shot is an intentionally harmless artillery shot or gunshot with intent to enact direct compliance and order to a hostile perpetrator or enemy forces. It is recognized as signalling intended confrontations on land, sea, and air.
The Civilian Marksmanship Program (CMP) is a national organization dedicated to training and educating U.S. citizens in responsible uses of firearms and airguns through gun safety training, marksmanship training, and competitions. The CMP is a federally chartered 501(c)(3) corporation that places a priority on serving youth through gun safety and marksmanship activities that encourage personal growth and build life skills.
A double tap is a shooting technique where two shots are fired in rapid succession at the same target with the same sight picture. Instruction and practice of the double-tap improves accuracy as shooters often do not have the gun fully extended on the first shot meaning the second shot of a double-tap is usually more accurate. The term hammer is sometimes used to describe a double tap in which the firearm's sights are not reacquired by the shooter between shots.
Exhibition shooting or trick shooting is a sport in which a marksman performs various feats of skill, frequently using non-traditional targets. Exhibition shooting tends to stress both speed and accuracy, often with elements of danger added.
Dry firing is the act of activating the firing mechanism a bow, crossbow, firearm or other projectile discharging weapon while unloaded or without live ammunition. The expression is also used to refer to practicing with an inert laser/infrared training platform and may also include the use of a target/feedback system.
In the United Kingdom police firearm policy varies by constituent countries. In Northern Ireland, all police officers carry firearms whereas in the rest of the United Kingdom, firearms are carried only by specially-trained firearms officers. The arming of police in Great Britain is a much debated topic.
The following are terms related to firearms and ammunition topics.
An underwater firearm is a firearm designed for use underwater. Underwater firearms or needleguns usually fire flechettes or spear-like bolts instead of standard bullets. These may be fired by pressurised gas.
Long range shooting is a collective term for shooting disciplines where the distance to target is significant enough that shooter has to put effort into calculating various ballistic factors, especially in regards to the deviating effects of gravity and wind. While shooting at shorter ranges, a shooter only has to slightly adjust the sights to compensate for limited bullet drop at most, but when the range is extended, wind drift will be the first factor affecting precision to the extent that it must be taken into serious account. Some would argue that long range shooting starts where assessment of wind, distance and various atmospheric conditions are equally important for the results as pure shooting skills - meaning that even if one conducts a technically perfect shot, the shooter will miss the target because of incorrect calculations, neglecting to take some elements into consideration, or merely due to unpredictable downrange conditions. It is widely accepted within interdisciplinary circles that for a standard rifle firing full-powered cartridges, "long range" means the target is more than 600 m (660 yd) away,, while "extreme long range" is generally accepted as when the target distance is more than 1,000 m (1,100 yd) away from the shooter.
The French Shooting Federation (FFTir), FrenchFédération Française de Tir, is the umbrella organization for sport shooting in France. It was founded in its current form in 1967, but has roots as far back as 1866.
