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 grain (1.9 g) bullet and 5 grains (0.32 g) of black powder, 25% more than the .22 Short on which it was based. It was designed for use in revolvers, but was soon chambered in rifles as well, in which it gained a strong reputation as a small game cartridge, and sold very well.
In 1887 the .22 Long case was combined with the heavier 40 grain (2.6 g) bullet of the .22 Extra Long of 1880 to produce the .22 Long Rifle giving a longer overall length, a higher muzzle energy and superior performance as a hunting and target round, rendering the .22 Long and .22 Extra Long obsolete. Many firearms designed for the .22 Long Rifle will chamber and fire the shorter round, though the .22 Long generally does not generate sufficient energy to operate semi-automatic guns. The one prominent survivor of the .22 Long is the .22 CB Long, a long-cased version of the .22 CB.

While the original .22 Long loading used the same powder charge as the .22 Long Rifle, the .22 Long bullet was significantly lighter, and the combination did not result in higher velocities for the .22 Long when fired from a rifle. The large barrel volume to chamber volume ratio of a .22 rimfire rifle means that the powder gasses have expanded as far as they can well before the bullet reaches the muzzle of a normal length rifle barrel, and the light .22 Long bullet has less inertia than the .22 Long Rifle.
This means that the 22lr ammo cci Long bullet actually slows down significantly before it exits the barrel. For farmers, or for those who only hunted small game such as squirrel or cottontail rabbit, the differences in performance between the .22 Long and .22 Long Rifle cartridges were of little importance. The quieter report and lower penetration of the .22 Long cartridge were often seen as desirable qualities.
