.223 Remington (5.56x45mm NATO)

About The .223 Remington Ammo is bottlenecked and rimless cartridge, developed in 1957 for the United States Army when the need for a small-caliber cartridge capable of delivering a high velocity arose. Even to this day, the .223 Remington Ammo is considered one of the most popular bullets and is used by various manual action and semiautomatic handguns. The .223 Remington Ammo offers better accuracy in NATO barrel chamberings than the 5.56x45mm Ammo. Even though these two bullets are pretty similar, they require significantly different chambers to be used properly. A longer barrel of the gun typically offers a greater muzzle velocity. When it comes to the .223 Remington Ammo, the muzzle velocity decreases or increases about 25.7 feet per second for an inch on barrel length. The overall length of this bullet is 57mm, and the bullet diameter measures 5.7mm. Velocity offered by the .223 Remington Ammo is 3,750 feet per second while producing an energy level of 959 ft. lbf. Manufacturer In the year 1962, Remington Arms designed the .223 Remington Ammo, and in the coming year of 1964, Remington Arms and Fairchild Industries developed this bullet. Uses The .223 Remington Ammo has proven to be the most popular cartridge in its category and is widely used in a manual action, semiautomatic rifles, and even handguns. The .223 Remington Ammo is used for hunting small to medium-sized game and self-defense.

.30 Remington AR

The .30 Remington AR cartridge was created in 2008 by Remington Arms to fill a perceived gap in performance on large game between the .223 Remington and larger cartridges such as the .308 Winchester. Design of the cartridge is considered a joint effort between companies under the "Freedom Group" name through a private equity firm and included such companies as Bushmaster, DPMS and Remington itself. It is a rebated rim cartridge designed to fit Remington's R-15 semiautomatic hunting rifle. It was designed to fit the dimensional constraints of the AR-15 magazine and is based on a modification of the .450 Bushmaster, which in turn was based on the .284 Winchester. Starting with a .450 Bushmaster case, Remington trimmed the length to 1.525" from the original 1.7" and necked it down to accept a conical .308" diameter bullet with a 25 degree shoulder. The rim size is .492" and because the round generates 55,000 psi, Remington opted to use a .308 rifle bolt in a 5.56 sized rifle for increased case support. The rim was widened from the .473" of the parent case to prevent the use of a weaker .450 Bushmaster bolt with this cartridge. With a 150 grain bullet, the round travels at 2575 fps. Performance tests between the .30 RAR and the .308 Winchester show that while the .30 RAR does have a good muzzle velocity, the energy it is capable of delivering on target at around 400 yards decreases significantly. Combined with the poorer ballistic coefficients of the lighter projectiles (.267 for the 125 grain Core-Lokt), this makes the .30 RAR a cartridge suited to ranges around 300 to 400 yards, although this could be extended with projectiles of higher ballistic coefficient (.341 for the Speer TNT 125 grain). A side effect of the short, wide case has meant that the Remington R-15 Rifle which was designed alongside the cartridge uses a four-round, single-stack magazine.
