While .223 ammo and 5.56 ammo have many similarities, they are completely different calibers of ammunition. Shooting 223 ammo through a firearm chambered in 5.56 is safe, but not always optimal. However, you should NEVER use 5.56 cartridges with a .223 weapon, as the higher pressure may cause a malfunction when firing. With that safety tip in mind, .223 Remington and 5.56x45mm NATO cartridges are an excellent choice for home defense, hunting, and range training. We carry a wide selection of 223/556 rifle ammo from some of the most popular ammunition brands including Winchester, Hornady, and Federal Premium.
