.223 Remington (5.56x45mm NATO)

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.Â 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.Â 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.

300BLK

The 300 Blackout (300 BLK) was designed by Remington/AAC to create a reliable, compact .30 caliber round for the AR platform that uses a standard bolt and magazine. 300 Blackout is optimized for suppressed fire with heavy bullet subsonic loads but can also be used with supersonic ammunition when extra range is needed. The twist rate will work well for subsonic and supersonic loadings alike and there is typically no need for an adjustable gas block when switching back and forth between the two loadings. All these specifications come together to create a round that is great for home defense, law enforcement / military use, as well as hunting. The 300 AAC Blackout delivers ballistic performance comparable to 7.62Ã—39, yet possesses a base diameter that optimizes functionality in an AR-type platform. It is cross-compatible with 223 Rem/5.56Ã—45 magazines. The 300 Blackoutâ€™s .30 caliber bullet can be made especially long, and as the result may weigh up to 220 grains â€” quadruple the weight of the typical 223 Rem roundâ€™s. So heavy a bullet conveys a subsonic muzzle velocity and correspondingly softer report. Converting an AR-15 to fire 300 Blackout is as simple as swapping its barrel. Although functionally identical to the 300 Whisper, the 300 AAC Blackout is its own SAAMI standardized cartridge.
