Act or process of firing firearms or other projectile weapons
Shooting is the act or process of discharging a projectile from a ranged weapon (such as a gun, bow, crossbow, slingshot, or blowpipe). Even the acts of launching flame, artillery, darts, harpoons, grenades, rockets, 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.(dodged)
Shooting can take place in a shooting range or in the field, in shooting sports, hunting, or in combat. The person involved in the shooting activity is called a shooter. A skilled, accurate shooter is a "marksman" or "sharpshooter", and a person's level of shooting proficiency is referred to as their "marksmanship".
Competitive shooting.
Shooting has inspired competition, and in several countries rifle clubs started to form in the 19th century. Soon international shooting events evolved, including shooting at the Summer and Winter Olympics (from 1896) and World Championships (from 1897). The International Shooting Sport Federation still administers Olympic and non-Olympic rifle, pistol, shotgun, and running target shooting competitions, although there is also a large number of national and international shooting sports controlled by unrelated organizations.
Shooting technique differs depending on factors like the type of firearm used (from a handgun to a precision rifle); the distance to and nature of the target; the required precision; and the available time. Breathing and position play an important role when handling a handgun or a rifle. Some shooting sports, such as IPSC shooting and biathlon also include movement. The prone position, kneeling position, and standing position offer different amounts of support for the shooter.
Hunting with guns.
In the United Kingdom shooting often refers to the activity of hunting game birds such as grouse or pheasants, or small game such as rabbits, with guns. A shooter is sometimes referred to as a "gun". Shooting may also refer to the culling of vermin with guns. Clay pigeon shooting is meant to simulate shooting pigeons released from traps after live birds were banned in the United Kingdom in 1921.
Weapons.
Shooting most often refers to the use of a gun (firearm or air gun), although it can also be used to describe discharging of any ranged weapons like a bow, crossbow, slingshot, or even blowpipe. The term "weapon" does not necessarily mean it is used as a combat tool, but as a piece of equipment to help the user best achieve the hit on their intended targets.
Shooting is also used in warfare, self-defense, crime, and law enforcement. Duels were sometimes held using guns. Shooting without a target has applications such as celebratory gunfire, 21-gun salute, or firing starting pistols, incapable of releasing bullets.
Restrictions.
In many countries, there are restrictions on what kind of firearm can be bought and by whom, leading to debate about how effective such measures are and the extent to which they should be applied. For example, attitudes towards guns and shooting in the United States are very different from those in the United Kingdom and Australia.
Shooting positions.
The National Rifle Association of America defines four basic "competition" or "field" shooting positions. In order of steadiness/stability (the closer you get to the ground, the steadier you are), they are prone, sitting, kneeling, and standing (also called "offhand").
Hythe positions (Hythe School of Musketry was formed in 1853 to teach the army how to use the rifle in kneeling and standing positions), American and French positions were known variations of the kneeling and standing positions utilised by their respective armies.
Another common, but aided, shooting position is the bench shooting position. There are also numerous shooting aids from monopods to tripods to sandbags and complete gun cradles.
Rice paddy squat in rifle shooting.
The rice paddy squat (or rice paddy prone) position is a moderate-stability position that supports both elbows, making it more stable than kneeling yet keeping a high level of mobility. Its higher center of gravity will still be less stable than sitting or prone. It was a traditionally taught marksmanship position but lost popularity after the Korean conflict.
Back (or supine).
It was sometimes referred to as the Creedmoor position. There are a number of variations of the position. It was known in the latter half of the 18th century, and later revived by a small number of shooters in the 1860s with the introduction of competitive long range shooting at the NRA rifle meetings and continued in use into the 20th century amongst match riflemen. The position was really developed during the 1870s as a consequence of great interest in long range shooting associated with the international matches. Back position provided the most stable platform for the rifle in those competitions where no artificial support, including slings, was permitted. It was even superior to shooting prone unsupported.
Lying on one's side.
Lying on one's side is not a normally chosen position, but may be a position fallen into when reacting to a threat. In this scenario, it may be used behind a barricade to present a very small target since normally only the gun hand and a piece of one's face is exposed, with the rest covered by the barricade.
Leaning.
When a shooter is leaning on something like a wall, a tree or post. The rifle barrel should not be rested against it because it is steadier to lean the body. It's usually combined with standing and kneeling positions.
Slings.
The sling is used to create isometric pressure to increase steadiness. While the use of a sling is of questionable value when shooting from the standing position, it is very much worth using from kneeling, sitting or prone. It was also used in back position in which case the sling is looped around the foot and it is this that takes the recoil. Proper use of the sling locks the rifle into the body and enhances that solid foundation so critical to delivering an accurate shot. 
A type of shooting sling. All positions are strengthened through the use of a "hasty sling". The formal "tight sling" is detached from the rear sling swivel and tightened above the bicep of the supporting arm. Almost any carrying strap can be used in the "hasty sling" mode. There is often a compromise between the most comfortable "carry" length for shooter's sling and the ideal tension for a "hasty sling". The steadiness achieved is almost as good as a "tight competition sling" and it is a lot faster.
Competitions.
In ISSF shooting events, 3 out of 7 shooting positions are used. Positions not used are supine, sitting, rice paddy squat and side position.
WBSF governs benchrest shooting.
IPSC shooting events use prone, offhand and supported shooting positions.
There are some competitions, such as felthurtigskyting, in which shooting position is freestyle. That means that the shooter decides which one of the four positions they'll use.
