Here's a wonderful new way to collect valuable, hard-asset silver. Containing a full 2 ounces of .999 fine investment grade silver, these 2.72 bullets are a near exact, non-firing replica of the standard NATO cartridge (also called a .308). This new ammunition was designed with a shorter cartridge length that worked more efficiently in newer, detachable-magazine rifles. It was first used by the U.S. in the M14 infantry rifle and M60 machine gun. The 2-oz. silver content is inscribed on the bottom of each.
