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. 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
