context_page_description: An air gun, or airgun, is a gun that fire projectiles pneumatically with compressed air or other gases that are pressurized without involving any chemical reactions, in contrast to a firearm, which pressurizes gases chemically by oxidation of combustible propellants that generates propulsive energy by breaking molecular bonds. Both the "long gun" and "handgun" forms typically propel metallic projectiles that are either diabolo-shaped pellets or spherical shots called BBs, though in recent years Minié ball-shaped slugs are gaining more popularity. Certain types of air guns may also propel darts or arrows.
  The first air guns were developed as early as the 1500s, and have since been used in hunting, sporting and warfare. There are three different power sources for modern air guns, depending on the design: spring-piston, pneumatic, or bottled compressed gas.
context_section_description: Air guns represent the oldest pneumatic technology. The oldest existing mechanical air gun, a bellows air gun dating back to about 1580, is in the Livrustkammaren Museum in Stockholm. This is the time most historians recognize as the beginning of the modern air gun.
  Throughout 17th to 19th century, air guns in calibers .30–.51, were used to hunt big-game deer and wild boar. These air rifles were charged using a pump to fill an air reservoir and gave velocities from 650 to 1,000 feet per second (200–300 m/s). They were also used in warfare, the most recognized example being the Girandoni air rifle.
  At that time, they had compelling advantages over the primitive firearms of the day. For example, air guns could be discharged in wet weather and rain (unlike both matchlock and flintlock muskets), and discharged much faster than muzzle-loading guns. Moreover, they were quieter than a firearm of similar caliber, had no muzzle flash, and were smokeless. Thus, they did not disclose the shooter's position or obscure the shooter's view, unlike the black powder muskets of the 18th and 19th centuries.
  In the hands of skilled soldiers, they gave the military a distinct advantage. France, Austria and other nations had special sniper detachments using air rifles. The Austrian 1770 model was named Windbüchse (literally "wind rifle" in German). The gun was developed in 1768 or 1769 by the Tyrolean watchmaker, mechanic and gunsmith Bartholomäus Girandoni (1744–1799) and is sometimes referred to as the Girandoni air rifle or Girandoni air gun in literature (the name is also spelled "Girandony," "Giradoni" or "Girardoni".) The Windbüchse was about 4 ft (1.2 m) long and weighed 10 pounds (4.5 kg), about the same size and mass as a conventional musket. The air reservoir was a removable, club-shaped, butt. The Windbüchse carried twenty-two .51 caliber (13 mm) lead balls in a tubular magazine. A skilled shooter could fire off one magazine in about thirty seconds. A shot from this air gun could penetrate an inch thick wooden board at a hundred paces, an effect roughly equal to that of a modern 9×19mm or .45 ACP caliber pistol.
  Circa 1820, the Japanese inventor Kunitomo Ikkansai developed various manufacturing methods for guns, and also created an air gun based on the study of Western knowledge ("rangaku") acquired from the Dutch in Dejima.
  The Lewis and Clark Expedition (1804) carried a reservoir air gun. It held 22 .46 caliber round balls in a tubular magazine mounted on the side of the barrel. The butt served as the air reservoir and had a working pressure of 800 psi (55 bar). The rifle was said to be capable of 22 aimed shots per minute and had a rifled bore of 0.452 in (11.5 mm) and a groove diameter 0.462 in (11.7 mm).
  One of the first commercially successful and mass-produced air guns was manufactured by the William F. Markham's Markham Air Rifle Company in Plymouth, Michigan, US. Their first model air gun was the wooden Challenger, marketed in 1886. In response, Clarence Hamilton from the neighboring Plymouth Air Rifle Company (later renamed to Daisy Manufacturing Company in 1895) marketed their all-metal Daisy BB Gun in early 1888, which prompted Markham to respond with their Chicago model in 1888 followed by the King model in 1890. The Chicago model was sold by Sears, Roebuck for 73 cents in its catalog. In 1928 the name of the Markham company was changed to King Air Rifle Company after the company was purchased by Daisy in 1916 after decades of intense competition, and continued to manufacture the "King" model air rifle until 1935 before ceasing operation altogether in the 1940s.
  During the 1890s, air rifles were used in Birmingham, England for competitive target shooting.  Matches were held in public houses, which sponsored shooting teams.  Prizes, such as a leg of mutton for the winning team, were paid for by the losing team.  The sport became so popular that in 1899, the National Smallbore Rifle Association was created.  During this time, over 4,000 air rifle clubs and associations existed across Great Britain, many of them in Birmin
