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).
The .222 Remington Magnum was created by lengthening the case and shortening the neck of the highly accurate and very popular .222 Remington cartridge, which dominated varmint and benchrest shooting during the 1950s. Case capacity is about 20% greater than that of the .222 Remington, producing moderately higher muzzle velocities.
The .222 Remington dominated the benchrest world from the mid-1950s until around 1975, when the wildcat 6 mm PPC, based on a modified .220 Russian case (which is in turn a boxer-primed derivative of the military 7.62×39mm), took over as the most accurate cartridge.
The rarest is the one chambered in .223 Remington; only 227 were produced—most in the final year of production. [citation needed] Before it was officially added to the line, you could order a Model 600 out of the custom gun shop in .223. At least one Model 600 in .223 came out of the Remington Custom Shop in 1966. A successor model, the ...
The Remington 788 is a bolt-action, centerfire rifle that was made by Remington Arms from 1967 to 1983. It was marketed as an inexpensive yet accurate hunting rifle to compete with other gun companies' less expensive rifles alongside their more expensive Model 700 line. [2]
Subsequently, the case was shortened to reduce powder capacity to a volume more suited to the shorter barrel of a pistol. The resulting cartridge, the .221 Fireball, produced factory-loaded velocities of over 825 m/s (2,700 ft/s) from the short barrel, and accuracy rivaling the parent .222 Remington, one of the most accurate cartridges made.

To obtain maximum accuracy, bullet weight and form are matched to the rifling twist rate of the barrel. Typically, 68 gr (4.41 g) bullets are used in barrels with twist rates of 1 in 13 inch (1 in 330 mm), while 1 in 15 inch (1 in 380 mm) barrel twists can accommodate lighter 58 or 60 gr (3.76 or 3.89 g) accurately.
The AR-15 rifle usually comes chambered for either the military cartridge 5.56×45mm or the .223 Remington. Because of the pressures associated with the 5.56×45mm, it is not advisable to fire 5.56×45mm rounds in an AR-15 marked as .223 Remington, since this can result in damage to the rifle or injury to the shooter.
