The .223 Rem is one of the most popular rounds in today’s market. Developed from the .222 Remington, the .223 was designed to achieve ballistics for military use.
The .223 Rem in its military form is known as the 5.56x45mm NATO. The differences between the two are the pressures that they are loaded at and the chamber of the firearms themselves.
There are so many rifles and handguns chambered in .223 being produced that it would be just about impossible to keep track of all of them. The .223 can be used for a wide range of activities including competition shooting and hunting.
