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.
The 5.56×45mm NATO is a rimless bottlenecked centerfire intermediate cartridge family developed in the late 1970s in Belgium by FN Herstal. It consists of the SS109, L110, and SS111 cartridges. On 28 October 1980, under STANAG 4172, it was standardized as the second standard service rifle cartridge for NATO forces as well as many non-NATO countries. Though they are not identical, the 5.56×45mm NATO cartridge family was derived from and is dimensionally similar to the .223 Remington cartridge designed by Remington Arms in the early 1960s.
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour.
Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target.
A ricochet is a rebound, bounce, or skip off a surface, particularly in the case of a projectile. Most ricochets are caused by accident and while the force of the deflection decelerates the projectile, it can still be energetic and almost as dangerous as before the deflection. The possibility of ricochet is one of the reasons for the common firearms safety rule "Never shoot a bullet at a flat, hard surface." Ricochets can occur with any caliber, but short or round ricocheting bullets may not produce the audible whine caused by tumbling irregular shapes. Ricochets are a hazard of shooting because, for as long as they retain sufficient velocity, ricocheting bullets or bullet fragments may cause collateral damage to animals, objects, or even the person who fired the shot.
The 9×19mm Parabellum is a rimless, centerfire, tapered firearms cartridge.
The 7.62×25mm Tokarev cartridge is a Soviet rimless bottleneck pistol cartridge widely used in former Soviet states and in China, among other countries. The cartridge has since been replaced in most capacities by the 9×18mm Makarov in Russian service.
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.
The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness. The basic principle, as with all common measures of hardness, is to observe a material's ability to resist plastic deformation from a standard source. The Vickers test can be used for all metals and has one of the widest scales among hardness tests. The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be confused with pressure, which uses the same units. The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force, and is therefore not pressure.
Metallic silhouette shooting is a group of target shooting disciplines that involves shooting at steel targets representing game animals at varying distances, seeking to knock the metal target over. Metallic silhouette is shot with large bore rifles fired freehand without support out to 500 meters, and with large bore handguns from the prone position with only body support out to 200 meters. Competitions are also held with airguns and black-powder firearms. A related genre is shot with bow and arrow, the metal targets being replaced with cardboard or foam. The targets used are rams, turkeys, pigs, and chickens, which are cut to different scales and set at certain distances from the shooter depending on the specific discipline.
The International Practical Shooting Confederation (IPSC) is the world's largest shooting sport association, and the largest and oldest within practical shooting. Founded in 1976, the IPSC nowadays affiliates over 100 regions from Africa, Americas, Asia, Europe, the Middle East, and Oceania. Competitions are held with pistols, revolvers, rifles, and shotguns, and the competitors are divided into different divisions based on firearm and equipment features. While everyone in a division competes in the Overall category, there are also separate awards for the categories Lady, Super Junior, Junior, Senior, and Super Senior.
Armour with two or more plates spaced a distance apart falls under the category of spaced armour. Spaced armour can be sloped or unsloped. When sloped, it reduces the penetrating power of bullets and solid shot, as after penetrating each plate projectiles tend to tumble, deflect, deform, or disintegrate; spaced armour that is not sloped is generally designed to provide protection from explosive projectiles, which detonate before reaching the primary armour. Spaced armour is used on military vehicles such as tanks and combat bulldozers. In a less common application, it is used in some spacecraft that use Whipple shields.
Frangible bullets are intended to disintegrate into tiny particles upon target impact to minimize their penetration of other objects. Small particles are slowed more rapidly by air resistance, and are less likely to cause injury or damage to persons and objects distant from the point of bullet impact.
The United States Practical Shooting Association(USPSA) is the national governing body of practical shooting in the United States under the International Practical Shooting Confederation (IPSC). Its over 35,000 active members and over 500 affiliated clubs make USPSA the largest practical shooting organization in the United States and the second largest region within IPSC after the Russian Federation of Practical Shooting. USPSA publishes a monthly member magazine called Front Sight.
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.
Power factor (PF) in practical shooting competitions refers to a ranking system used to reward cartridges with more recoil. Power factor is a measure of the momentum of the bullet, which to some degree reflects the recoil impulse from the firearm onto the shooter.
Dynamic Sports Shooting Norway (DSSN), NorwegianDynamisk Sportsskyting Norge (DSSN), is the Norwegian association for practical shooting under the International Practical Shooting Confederation. It was constituted in 1979 as Norges Forbund for Praktisk Skyting (NFPS), and changed its name to Dynamisk Sportsskyting Norge in 2013.
Long range shooting is a collective term for shooting disciplines where the distance to the target is significant enough that the 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.
Shooting targets are objects in various forms and shapes that are used for pistol, rifle, shotgun and other shooting sports, as well as in darts, target archery, crossbow shooting and other non-firearm related sports. The center is often called the bullseye. Targets can for instance be made of paper, "self healing" rubber or steel. There are also electronic targets that electronically can provide the shooter with precise feedback of the shot placement.
A bullet trap is a device to stop and collect projectiles fired at a shooting range to prevent overpenetrations and stray shots. Bullet traps typically use friction, impact or gradual deceleration to stop bullets. They can function as a backstop by themselves or be part of a larger backstop, e.g. placed in front of a thick rubber wall or a bay of sand.
