The .22 Long Rifle rimfire cartridge is a long established variety of ammunition, and in terms of units sold is still by far the most common in the world today. The cartridge is often referred to simply as a ".22" and various rifles, pistols, revolvers, and even some smoothbore shotguns have been manufactured in this caliber. The .22 Long Rifle and its derivative cartridges use a heeled bullet, which means that the bullet is the same diameter of the case, and has a narrower "heel" portion that fits in the case.

Performance

The .22 LR is inexpensive, often costing less than two US cents per cartridge. It is effective within 150 meters (after 150 meters the ballistics of the round are such that the large "drop" will be difficult to compensate for). The relatively short effective range, low report and light recoil has made it a favourite as a target practice cartridge. The accuracy of the cartridge is good, but not exceptional; various cartridges are capable of the same or better accuracy. Still, the effectiveness of this cartridge is often underestimated. The newest commercial rimfire, the .17 Mach 2 is a .22 LR based cartrdige, firing a light .17 caliber bullet at a much higher velocity than the .22 LR. Many .22 LR firearms are being sold chambered for the .17 Mach 2, and modifying a .22 LR to shoot .17 Mach 2 often requires just a barrel change. The .17 Mach 2 extends the effective range significantly over the .22 LR. The disadvantage of the .17 Mach 2 is the price, which is several times that of the .22 LR, and the increased noise of firing caused by the higher muzzle pressure and supersonic bullet. External ballistics is the part of ballistics that refers to the behavior of a bullet after it exits the barrel and before it hits the target. ... The recoil when firing a gun is the backward momentum of a gun, which is equal to the forward momentum of the bullet or shell, due to conservation of momentum. ... (Redirected from . ...

As a hunting cartridge, the .22 LR is mainly used to kill small varmints such as rats and squirrels. It is also effective on rabbits closer than 75 meters. For greater range or larger game a more powerful cartridge should be used to ensure a clean kill. Examples include larger rimfire rounds such as the .22 WMR, .17 HMR, or any centrefire catridge. Like any bullet, the .22 LR is nonetheless dangerous and is capable of killing humans and other large animals. Hunting is, in its most general sense, the pursuit of a target. ...

Variants

There are a variety of different types of .22 Long Rifle (or ".22 LR") loads. They are sometimes divided into 3 categories; subsonic, standard and hyper-velocity (or ultra-velocity). The subsonic rounds have a muzzle velocity of 330 m/s or less and are often equipped with an extra heavy, 2.9-3.9 gram bullet. The standard rounds have a supersonic muzzle velocity and a "normal" weight, 2.5-2.6 gram bullet. The so-called hyper-velocity bullets may have a muzzle velocity of 450-550 m/s and this velocity is partially due to the light bullets they use. The bullets are usually around 1.9-2.2 grams in weight. The bullets themselves are in all cases usually either solid or hollow-point bullets. Subsonic has two possible meanings: A speed lower than the speed of sound is called subsonic. ... A guns muzzle velocity is the speed at which the projectile leaves the muzzle of the gun. ... 0. ...

Special shot cartridges, usually loaded with #12 shot (see shotgun shell) in this caliber have been made and these are ideal for pest control at very short ranges. Such rounds will either have a longer brass case that is crimped closed, or a translucent plastic "bullet" that contains the shot and shatters upon firing. In a specially made .22 bore shotgun, the shotshells can be used for short range skeet shooting and trap shooting at special, scaled down clay targets.

.22 LR High Velocity

The CCI Stinger is a somewhat improved .22 LR cartridge that increases the bullet velocity with a longer case, a stronger charge and copper plating on a somewhat smaller bullet. The case is longer than that of the normal Long Rifle cartridge but Stingers will fit in most Long Rifle firearms. The powder is designed to burn more slowly and thus make the most use of the length of a rifle barrel. The extra case length is compensated by a shorter bullet, which is only available as a jacketed hollowpoint. The thin copper layer on the bullet functions as a lubricant and reduces the friction between the high velocity bullet and the barrel, thus reducing barrel wear. It also has an oxidation-preventing effect on the lead bullet. Lead tends to oxidise if stored over long periods of time and as a result of this, the bullet's diameter increases to a level that might both prevent the insertion of the cartridge in the chamber and might cause the pressure in the barrel to rise to a dangerously high level. The increase in pressure may lead to the case rupturing and potential danger to the shooter. Standard and subsonic cartridges tend to use a type of wax for the same purpose.

Usage

Today .22 Long Rifle ammunition is mainly being used for hunting small pests, for sports shooting and for cheap training. .22 LR is the choice for several ISSF shooting events: 50 m Rifle, 50 m Pistol, 25 m Pistol, 25 m Rapid Fire Pistol and 25 m Standard Pistol, plus divisions of metallic silhouette and pin shooting, most high school, collegiate, Boy Scouts of America, and 4H shooting events, and many others. With high quality ammunition, the .22 Long Rifle can be quite accurate. Its main advantages are low cost, low recoil and low noise. Its main disadvantage is its minimal power; it is only suitable for the smallest game, and as a defensive cartridge it is considered very underpowered, though the small size allows very lightweight, easily concealable handguns which can be carried in circumstances where anything larger would be impractical.

The tiny case of the .22 Long Rifle, and the subsonic velocities (using standard velocity ammunition) make it well suited for use with a suppressor. The low volume of powder gasses mean that .22 suppressors are often no larger than a bull barrel; the Ruger 10/22 and Ruger MK II are common choices, due to their reliability and low cost, and the resulting product is often nearly indistinguishable from a bull barrel model (although weighing far less). Where suppressors are only minimally restricted, a .22 Long Rifle with a suppressor is often a favored firearm for plinking, as it doesn't require hearing protection or disturb the neighbors.

Suppressed .22 caliber pistols are often found in the arsenals of special forces, intelligence agencies, and organized crime organizations. Gary Powers, for example, was issued a suppressed High Standard pistol for the fight in which he was shot down. The .22 LR has also been found to be the weapon of choice for several suspected Mafia assassinations, with the victim usually being shot at close range in the head. The notion of the .22 LR as a mob weapon has steadily begun to enter into pop culture in recent years, being featured in the movie Assassins and in the television series The Sopranos. Even without a suppressor, a .22 Long Rifle pistol is far quieter than any but the smallest centerfire cartridges. Organized crime is crime carried out systematically by formal criminal organizations. ...
