CCI (Cascade Cartridge Inc.), based in Lewiston, Idaho, manufactures rimfire ammunition, centerfire handgun ammunition, and primers for reloaders and industrial ammunition production. CCI made the first mini-mag rimfire ammunition in 1963, and in 1975 developed the Stinger, a high velocity .22 Long Rifle product.
The CCI Stinger was the first hyper-velocity .22 LR cartridge and provided a significant increase in velocity and energy over standard rimfire rounds. The Stinger case is slightly longer at .702 in (17.8 mm) versus .613 in (15.6 mm) for the long rifle case, but the plated hollow point bullet is lighter and shorter at 32 gr (2.1 g), giving the ...
.22 long rifle extra long (LR EX), a variant of .22LR with a longer casing but identical overall cartridge dimensions (see CCI Stinger).22 short, a cartridge used mostly in pocket pistols and mini-revolvers.22 Winchester Magnum Rimfire (WMR), a magnum cartridge that is longer and more powerful than the .22 LR
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.
This was followed by the .22 Extra Long in 1880, with a longer case and heavier bullet than the .22 Long. .41 Swiss rimfire cartridge.22 Long Rifle – subsonic hollow point (left), standard velocity (center), hyper-velocity "Stinger" hollow point (right)
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 weight of the bullet is a key part of achieving a very high velocity for a rimfire round. It weighs only 17 grains (1.10 g) vs 30-40 grains (1.94-2.59 g) of a typical .22 LR bullet. [2]
