          Brass: Offered in new brass only.

          *IMPORTANT: Though both cartridges look identical, 5.56 is loaded to a higher pressure than .223, which is why rifles chambered for a 5.56 cartridge can fire .223, but it is not recommended that 5.56 cartridges are fired out of a rifle chambered for .223
