cartridge. Introduced in 1950, it was the first commercial
rimless .22 (5.56 mm) cartridge made in the United States. As such, it was an entirely new design, without a
parent case. The .222 Remington was a popular target cartridge from its introduction until the mid-1970s and still enjoys a reputation for accuracy. It remains a popular vermin or "varmint" cartridge at short and medium ranges with preferred bullet weights of 40–55 grains and muzzle velocities from 3,000 to 3,500 ft/s (915–1,067 m/s).
Introduction
The .222 Remington was developed by
Mike Walker, an engineer at Remington, who shot it in a benchrest competition in 1950 at the Johnstown, New York, gun club.
It was introduced with the

.220 Swift and
.22-250 Remington provided more reach than the .222 Remington. These larger cartridges have roughly 50% more power than the .222, but also cause more muzzle blast and barrel erosion.
Legacy

The .222 Remington was eventually eclipsed in benchrest competition by the
6mm PPC.
When the US military was looking for a new smallbore rifle cartridge, Remington started with the .222 Remington, and stretched it to increase powder capacity by about 20% in 1958 to make the
.222 Remington Magnum. The greater powder capacity put the velocities between the standard .222 Remington and the .22-250. The cartridge was not accepted by the military, but it was introduced commercially.
[Speer Reloading Manual Number 12, 1994, Blount, Inc., Lewiston, ID.] In 1963, the .222 Remington Special, also based on a stretched .222 case, was adopted along with the new

as the
.223 Remington /
5.56mm NATO. The NATO cartridge had a capacity only 5% less than the Magnum. Given the close performance to other cartridges and military acceptance, both the .222 Remington and the .222 Magnum faded quickly into obsolescence, being replaced by the .223 Remington.
While the .222 Remington is rarely found in current production in America, its derivative cartridges are among the most popular in the world. In addition to the .222 Magnum and .223 Remington, the .222 has also served as the parent case for the
