Blowgun in the context of "Shooting"

An air gun or airgun is a gun that uses compressed air or other pressurized gases to fire projectiles, reminiscent of the principle behind the ancient blowgun. This is in contrast to a firearm, which shoots projectiles using pressure generated via combustion of a chemical propellant, most often black powder in antique firearms and smokeless powder in modern firearms.

Air guns come in both long gun (air rifle) and handgun (air pistol) forms. Both types typically propel metallic projectiles that are either diabolo-shaped pellets or spherical shots called BBs, although in recent years Minié ball-shaped cylindro-conoidal projectiles called slugs are gaining more popularity. Certain types of air guns (usually air rifles) may also launch fin-stabilized projectile such as darts (e.g., tranquilizer guns) or hollow-shaft arrows (so-called "airbows").

Darts are airborne ranged weapons. They are designed to fly such that a sharp, often weighted point will strike first. They can be distinguished from javelins by the presence of fletching (feathers on the tail) and a shaft that is shorter or more flexible. Darts can be propelled by hand or with the aid of a hand-held implement such as a blowgun. They can be distinguished from arrows because they are not used with a bow.

Darts have been used since pre-history. The plumbatae were lead-weighted darts thrown by infantrymen in Antiquity and the Middle Ages. Darts can be propelled by a number of means. The atlatl uses leverage to increase the velocity of the dart, the kestros increases the range of propelled darts using a sling, and the exhalation of a person's breath through a blowgun propels small stone points or poisoned needles with pneumatic force.

In the classification of archaeological cultures of North America, the Woodland period of North American pre-Columbian cultures spanned a period from roughly 1000 BCE to European contact in the eastern part of North America, with some archaeologists distinguishing the Mississippian period, from 1000 CE to European contact as a separate period. The term "Woodland Period" was introduced in the 1930s as a generic term for prehistoric sites falling between the Archaic hunter-gatherers and the agriculturalist Mississippian cultures. The Eastern Woodlands cultural region covers what is now eastern Canada south of the Subarctic region, the Eastern United States, along to the Gulf of Mexico.

This period is variously considered a developmental stage, a time period, a suite of technological adaptations or "traits", and a "family tree" of cultures related to earlier Archaic cultures. It can be characterized as a chronological and cultural manifestation without any massive changes in a short time but instead having a continuous development in stone and bone tools, leather crafting, textile manufacture, cultivation, and shelter construction. Many Woodland peoples used spears and atlatls until the end of the period, when they were replaced by bows and arrows; however, Southeastern Woodland peoples also used blowguns.

The cylindro-conoidal bullet is a type of muzzleloading firearm projectile with a convexly cone-like front end ("nose") and a cylindrical rear body, invented by Captain John Norton of the British 34th Regiment in 1832. It had a cavitied base, so when fired, the thin concavity wall ("skirt") would expand outwards and seal up the bore diameter. The origin of his idea is an interesting one: when in southern British India, he examined the blow pipe darts used by the natives and found that their base was formed of elastic lotus pith, which by its expansion against the inner surface of the blow pipe prevented the leakage of air past it.

In 1836, Mr. W. Greener, a London-based gunsmith, improved on Norton's bullet design by inserting a conoidal wooden plug into its base. Although both inventions were rejected by the British Ordnance Department, the idea was taken up in France, and in 1849 Claude-Étienne Minié adopted Greener's design and produced the "Minié ball".
