The 222 Remington Magnum was designed by Remington in 1958 as a prospective military round for the United States. The.222 Remington Magnum was put into the commercial market after it was rejected. Its ballistic performance was based on the 40, 50, and 55 grain bullets, which had speeds of 3,818 feet per second (40 gr), 3,476 feet per second (50 gr), and 3,294 feet per second (55 gr) (55 gr). Finally, the velocity of 3,818 ft/s (40 gr), 3,476 ft/s (50 gr), and 3,294 ft/s were determined (55 gr). The 222 Remington Magnum was only a short-lived commercially manufactured cartridge.
The 222 Remington Magnum was made by extending the casing and shortening the neck of the popular and very accurate. During the 1950s, the 222 Remington cartridge dominated varmint and bench rest shooting. In 1963, the United States Army accepted the 5.56mm and chose the.223, effectively killing.222 Magnum sales overnight. The .222 Remington Magnum ended up serving as the basis for the German-developed 5.6×50mm Magnum sporting cartridge.
Typical factory loads for the.222 Remington propel a 50 grain spitzer bullet at 3,140 feet per second (fps) with 1,094 feet per second of muzzle energy (ME). The bullet will strike 1.9" high at 100 yards, 1.7" high at 150 yards, 0 at 200 yards, 3.6" low at 250 yards, and 9.7" low at 300 yards if the factory load is zeroed at 200 yards. The recoil with a 50 grain factory load in a light 7 pound rifle is roughly 3.5 ft. lbs. Overall, the 222 Remington Magnum is a good varmint cartridge with a range of roughly 225 yards.
