The .22 ILARCO / 5.7x24mmRF, also known as the .22 Winchester Short Magnum Rimfire or .22 American, [2] [3] was a rimfire cartridge designed in 1987 for the American-180 rimfire submachine gun. At the time the cartridge was created, the design of the American-180 had been taken over by the Illinois Arms Company, Inc., hence the ILARCO name.
The American-180 is a submachine gun developed in the 1960s which fires the .22 Long Rifle or .22 ILARCO cartridges from a pan magazine. The concept began with the Casull Model 290 that used a flat pan magazine similar to designs widely used prior to World War II. Only 87 Casull M290s were built, as the weapon was expensive to manufacture. [5]
The Aguila SubSonic Sniper round uses a .22 short case with a 60-grain (3.9 g) bullet (twice the weight of the .22 short bullet and 50% heavier than a .22 long rifle bullet) giving an overall length of a .22 long rifle round, making categorizing the SSS problematic: while the SSS case size is .22 short, the firing chamber of the barrel must be ...
A .22 Short, .22 long rifle, .22 Winchester Magnum, and a .22 Hornet. The .22 long rifle uses a straight-walled case. Depending upon the type and the feed mechanism employed, a firearm that is chambered for .22 long rifle may also be able to safely chamber and fire shorter rimfire cartridges, including the .22 BB, .22 CB, .22 short, .22 long.

Using the same 40 gr (2.6 g) outside-lubricated bullet later adapted for the much more common .22 long rifle, [2] the extra long was loaded with 6 gr (389 mg) of black powder. [2] Originally, it slightly outperformed the .22 LR, but was "not noted for great accuracy", [2] while later smokeless loads achieved about the same muzzle velocity as ...
