The CCI .22 CB Short and .22 CB Long use the same 29-grain bullet as the regular .22 Short and .22 Long. The CCI CB rounds have muzzle velocities of 720 feet per second (ft/s) for an impact energy of 33 foot/pounds (ft-lb). The standard .22 Short and .22 Long fire the same bullet weight at 1,045 ft/s for 70 ft-lb.
The .22 long rifle, also known as the .22 LR or 5.7×15mmR, [4] [5] is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of firearms including rifles , pistols , revolvers , and submachine guns .
Rimfire ammunition is a type of metallic cartridge whose primer is located within a hollow circumferential rim protruding from the base of its casing. The most common rimfire cartridges are chambered for .17 caliber and .22 caliber .
In 1975, CCI engineers completed development of the first "hyper-velocity" .22 Long Rifle ammunition. This ammunition became known as the "CCI Stinger." [7] In early 2020, CCI introduced 14 new products. [8] CCI/Speer sells the Gold Dot line, component bullets, and handgun ammunition using a bonded copper-plated hollow point bullet.
The .22 long is a variety of .22 caliber (5.6 mm) rimfire ammunition.The .22 long is the second-oldest of the surviving rimfire cartridges, dating back to 1871, when it was loaded with a 29 gr (1.9 g) bullet and 5 gr (0.32 g) of black powder, 25% more than the .22 short on which it was based.
It combined the casing of the .22 Long with the 40-grain (2.6 g) bullet of the .22 Extra Long, giving it a longer overall length, a higher muzzle velocity, and superior performance as a hunting and target round, rendering the .22 Short, .22 Long, and .22 Extra Long cartridges obsolete.
.22 caliber, or 5.6 mm, refers to a common firearms bore diameter of 0.22 inch (5.6 mm) in both rimfire and centerfire cartridges. Cartridges in this caliber include the very widely used .22 Long Rifle and .223 Remington/5.56×45mm NATO. .22 inch is also a popular air gun pellet caliber, second only to the ubiquitous .177 caliber.
Subsonic loads for 9×19mm Parabellum commonly use 9.5 g (147 gr) bullets at velocities of 300 m/s (980 ft/s). For these ammunition loads, balancing bullet weight and velocity are required to ensure that the ammunition will still reliably cycle semi-automatic firearms. Subsonic ammunition with normal bullet weights often fails to function ...
