Air gun - Wikipedia, the free encyclopedia. An air gun (often called pellet gun or BB gun depending on the projectile) is any variety of pneumatic weapon that propels projectiles by means of compressed air or other gas, in contrast to firearms, which use a propellant charge. Both the rifle and pistol forms (air rifle and air pistol) typically propel metallic projectiles, either pellets, or BBs. Certain types of air guns, usually rifles, may also propel arrows or darts with feathers. History[edit]Air guns represent the oldest pneumatic technology. The oldest existing mechanical air gun, a bellows air gun dating back to about 1. Livrustkammaren Museum in Stockholm.
I have taken many small game animals with my.22 cal pellet gun. It requires better stalking skills, but that is a good skill to learn anyway. It requires better shooting skills, but that is also a good skill to hone in on. Hunting with a. ** Update from BSA - The rifle in the video is the older version, we have been informed - the even newer version has even better performance** REVIEW - BSA Lightning SE Air Rifle - Spring Powered Air Gun. Wow (laughing at RidgeRunner’s post), such a persnickity rifle! Is the gun really an accurate shooter if you have to go through just “exactly” the right hold? And, use “exactly” the right pellet? I don’t know about this, B.B. Reminds me.
The celebrated 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.

This is the time most historians recognize as the beginning of the modern air gun. In the 1. 7th century, air guns, in calibers . These air rifles were charged using a pump to fill an air reservoir and gave velocities from 6. They were also used in warfare, the most recognized example being the Girandoni Military Repeating 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 matchlockmuskets), and repeatedly discharged faster than muzzle- loading guns.[1] Moreover, they were quieter than a firearm of similar caliber, had no muzzle flash, and were smokeless.
---You do not need a FAC to increase the speed of the projectile above 495 fps. The lighter the 0,22 pellet you feed in the rifle, the faster the fps will be. But according to Canadian law if you reach speeds beyond 495 fps (measured by. Stock photos provided to us by the manufacturer do not necessarily represent the actual item being purchased. Please refer to the title and description on this. This version of the Discovery does not include a pump, tank, yoke or fill. Weihrauch HW95 - A classic springer air gun from the Weihrauch family. Take it with you to blast the pigeon's rats and rabbits, then hit a few targets before coming home. Taken from the big show, Episode 2.
Thus, they did not disclose the shooter's position or obscure the shooter's view, unlike the black powder muskets of the 1. 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 1. 77. Windb. Гјchse (literally "wind rifle" in German). The gun was developed in 1. Tyrolean watchmaker, mechanic and gunsmith Bartholom. Г¤us Girandoni (1.
Girandoni Air Rifle or Girandoni air gun in literature (the name is also spelled "Girandony," "Giradoni"[3] or "Girardoni".[4]) The Windb. Гјchse was about 4 ft (1. The air reservoir was a removable, club- shaped, butt. The Windb. Гјchse carried twenty- two . 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.
Г—1. 9mm or . 4. 5 ACP caliber pistol. Circa 1. 82. 0, 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.
Kunitomo air gun trigger mechanism. The celebrated Lewis and Clark Expedition (1. It held 2. 2 . 4. The butt served as the air reservoir and had a working pressure of 8. Pa). The rifle was said to be capable of 2. One of the first commercially successful and mass- produced air guns was manufactured by the W. F. Markham Co. Their first model air gun was called the Challenger and marketed in 1.
Their next model was the Chicago followed by the King. The Chicago model was sold by Sears, Roebuck for 7. In 1. 92. 8 the name of the company was changed to King Mfg. Co. and remained so until the company was purchased by the Daisy air gun company.[5]During the 1.
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 1.
National Smallbore Rifle Association was created. During this time over 4,0. Great Britain, many of them in Birmingham. During this time, the air gun was associated with poaching because it could deliver a shot without a significant report. Air guns are used for hunting, pest control, recreational shooting (commonly known as plinking), and competitive sports, such as the Olympic. Air Rifle and 1. 0 m Air Pistol events.
Field Target (FT) is a competitive form of target shooting in which the targets are knock- down metal silhouettes of animals, with a 'kill zone' cut out of the steel plate. Hunter Field Target (HFT) is a variation, using identical equipment, but with differing rules.
The distances FT and HFT competitions are shot at range between 7. HFT & 7. 3 and 5. FT, with varying sizes of 'reducers' being used to increase or decrease the size of the kill zone. In the UK, competition power limits are set at the legal maximum for an unlicensed air rifle, i. В·lbf (1. 6 J). Air gun power sources[edit]The different methods of powering an air gun can be broadly divided into 3 groups: spring- piston, pneumatic, and CO2.
These methods are used in both air rifles and air pistols.[6]Spring- piston[edit]Spring- piston air guns are able to achieve muzzle velocities near or greater than the speed of sound from a single stroke of a cocking lever or the barrel itself. The effort required for the cocking stroke is usually related to the power of the gun, with higher muzzle velocities requiring greater effort. Spring- piston guns operate by means of a coiled steel spring- loaded piston contained within a compression chamber, and separate from the barrel. Cocking the gun causes the piston assembly to compress the spring until the rear of the piston engages the sear.
The act of pulling the trigger releases the sear and allows the spring to decompress, pushing the piston forward, thereby compressing the air in the chamber directly behind the pellet. Once the air pressure has risen enough to overcome any static friction and/or barrel restriction holding the pellet, the pellet moves forward, propelled by an expanding column of air.
All this takes place in a fraction of a second, during which the air undergoes adiabatic heating to several hundred degrees and then cools as the air expands. Spring- piston guns have a practical upper limit of 1. Higher velocities cause unstable pellet flight and loss of accuracy. This is due to the extreme buffeting caused when the pellet reaches and passes transonic speed, then slows back down and goes through it again.
This is more than enough to destabilize it. Shortly after leaving the barrel, the supersonic pellet falls back below the speed of sound and the shock wave overtakes the pellet, causing its flight to be disrupted. Drag increases rapidly as pellets are pushed past the speed of sound, so it is generally better to increase pellet weight to keep velocities subsonic in high- powered guns. Sonic crack from the pellet as it moves with supersonic speed also makes the shot louder sometimes making it possible to be mistaken for firearm discharge.
Many shooters have found that velocities in the 8. Most spring piston guns are single- shot breech- loaders by nature, but multiple- shot guns have become more common in recent years.
Spring guns are typically cocked by a mechanism requiring the gun to be hinged at the midpoint (called a break barrel), with the barrel serving as a cocking lever. Other systems that are used include side levers, under- barrel levers, and motorized cocking, powered by a rechargeable battery. Spring piston guns, especially high- powered ones, recoil as a result of the forward motion of the piston. Although the recoil is less than that of some cartridge firearms, it can make the gun difficult to shoot accurately as the recoil forces are in effect whilst the pellet is still traveling down the barrel. Spring gun recoil has a sharp forward movement too, caused by the piston hitting the forward end of the chamber when the spring has fully expanded. These two reactions are known to damage scopes not rated for spring gun use.
Spring guns can also suffer from spring vibrations that reduce accuracy. These vibrations can be controlled by adding features like close- fitting spring guides or by aftermarket tuning done by "air- gunsmiths" who specialize in air gun modifications.
A common modification is the addition of viscous silicone grease to the spring, which both lubricates it and dampens vibration. The better quality spring air guns can have very long service lives, being simple to maintain and repair. Because they deliver the same energy on each shot, their trajectory is consistent. Most Olympic air gun matches through the 1.
Beginning in the 1. Today, the guns used at the highest levels of competition are powered by compressed air. Gas Spring[edit]Some makes of air rifle incorporate a gas spring instead of a mechanical spring. Pressurized air or nitrogen is held in a chamber built into the piston, and this air is further pressurized when the gun is cocked.
It is, in effect, a gas spring commonly referred to as a "gas ram" or "gas strut". Gas spring units require higher precision to build, since they require a low friction sliding seal that can withstand the high pressures when cocked. The advantages of the gas spring include the facility to keep the rifle cocked and ready to fire for long periods of time without long- term spring fatigue, lower recoil and faster "lock time" (the time between pulling the trigger and the pellet being discharged). The improvement in lock time results in better accuracy. Pneumatic[edit]Pneumatic air guns utilize compressed air as the source of energy to propel the projectile. Single- stroke and multi- stroke guns utilize an on board pump to pressurize the air in a reservoir. Pre- charged pneumatic guns' reservoirs are filled using either a high- pressure hand pump or by decanting air from a diving cylinder.
This design, having no significant movement of heavy mechanical parts during the firing cycle, produces lower recoil. Multi- stroke[edit]Multi- stroke pneumatic air guns require the pumping of an on- board lever to store compressed air within the air gun. Variable power can be achieved through this process, as the user can adapt the power level for long, or short- range shooting. Single- stroke[edit]. The Walther LGR single- stroke pneumatic match air rifle. A single motion of the cocking lever is all that is required to compress the air.
