This load uses a 40-grain bullet with a listed muzzle velocity of 1,070 ft/s when fired from a rifle-length barrel. For this category, consider CCI Standard Velocity ammunition. 22 Long Rifle is generally between 1,050 and 1,150 ft/s. Standard Velocity - CCI Standard Velocity 40 Grain Target This can be ideal for suppressed firearms. By eliminating the sonic boom associated with supersonic muzzle velocities, subsonic ammunition generates less noise. SubsonicĪ subsonic cartridge load achieves a muzzle velocity below the speed of sound. The most common are standard and high velocity, although you can also find subsonic and hyper-velocity loads for specialized applications.
22 Long Rifle ammunition falls into three categories, depending on muzzle velocity. 22 Extra Long, an 1880 rimfire cartridge, becoming obsolete.22 Long Rifle Velocity Variants 22 Long Rifle cartridge in 1887 by loading a heavier bullet into the. 22 Long Rifle is the world’s most common small-arms cartridge and the standard in rimfire designs. 22 Long followed this development in 1871, increasing the powder charge of the Short for increased velocity.22 Long Rifle (1887) 22 Short and Model 1 were commercially successful and demonstrated the utility of the new cartridge design.22 Long (1871) 22 Short, developed by Smith & Wesson for its Model 1 revolver. The next breakthrough in rimfire ammunition was the. As a result, it was perfect for parlor and gallery guns, especially in an era when hearing protection was non-existent.22 Short (1857) 22 BB Cap was quiet and produced little to no perceptible recoil. 22-caliber lead ball using only the force of the primer, the. 19th-Century Rimfire Ammunition TimelineĪ brief timeline can help shed some light on why the two rounds came to exist.22 BB (Bullet Breech) Cap (1845) As a result, they’re popular for teaching children to shoot, hunting rabbits and squirrels, shooting pests, and learning the principles of marksmanship. 22 Short and Long Rifle, are also lightweight, compact, relatively quiet, and generate minimal recoil.
Generally, rimfire ammunition is less expensive than centerfire ammunition.
Today, rimfire ammunition is popular for a variety of reasons. As the primer detonates, the sparks pass through the flash hole in the primer pocket, igniting the propellant. When the firing pin strikes the primer, it crushes the primary explosive against an internal anvil. The resulting incandescent particles ignite the propellant charge in the cartridge, firing the round.Ī centerfire cartridge, in contrast, uses a separate primer located in the center of the cartridge case head (hence the name). When the firing pin strikes the rim, it compresses the priming compound against the barrel face. In modern small-arms ammunition, there are two basic primer types - rimfire and centerfire.Ī rimfire cartridge contains an impact-sensitive primary explosive in the rim or extractor flange.
