The .223 Remington, often referred to as the .223 Rem, is one of the most common rifle calibers in the United States. As an intermediate rifle cartridge, .223 Rem loadings will produce a light recoil impulse and feature a light projectile. The rounds will typically yield a high velocity and feature a flat trajectory. While the cartridge and its NATO cousin have seen duty use, the .223 Rem has also established itself as a capable round as far as target shooting and hunting go as well. The round is enjoyed by shooters, both new and experienced, due to the light recoil and overall performance afforded by the cartridge.
There is a wide range of firearms on the market which will accommodate .223 Remington ammunition. Some of these firearms are purpose-built for .223 Remington ammunition while others are 5.56x45mm NATO firearms which will accept .223 Remington ammo. The most notable firearm chambered for .223 Remington is the AR-15, a popular semi-automatic rifle widely used for both recreational shooting and home defense. .223 Remington-specific firearms can also be found in the form of various semi-automatic and manual action firearms. These same types of firearms can be found in the form of 5.56x45mm NATO chambered firearms, albeit in greater numbers.
One of the most common examples of interchangeability on the market comes in the form of the relationship between 5.56x45mm NATO ammo and .223 Remington ammo. The .223 Remington served as the basis for developing the 5.56x45mm NATO, a fact which explains their nearly identical dimensions as far as projectiles and casings go. The biggest difference, however, is the fact that the 5.56x45mm NATO is a higher-pressure round than the .223 Remington. This means that 5.56x45mm NATO chambered firearms are able to accept .223 Remington ammunition.
The use of 5.56x45mm NATO ammunition in a firearm chambered in .223 Remington is ill-advised due to the increased pressure of the cartridge. While most firearms, regardless of caliber, are tested with overpressure loadings during the manufacturing process, a steady diet of ammunition of this type is not recommended. Luckily for shooters, the number of 5.56x45mm NATO chambered firearms outweighs the number of firearms exclusively chambered in .223 Remington. This means that most of the time, shooters will be able to safely shoot either 5.56x45mm NATO or .223 Remington ammunition in their firearm without any worries.
