About 7.62x51 NATO Ammunition
NATO adopted the 7.62x51mm in 1954 as its standard rifle cartridge. It served in the M14, FN FAL, G3 and M60, and it remains in use today in machine guns and designated marksman rifles.
Most military-style loads use 145 to 150 grain FMJ, often sold as M80 ball. Heavier 168 to 175 grain match loads are used for precision shooting.
7.62x51 and .308 Winchester have nearly identical dimensions, but military ammo can run different pressures and chamber specs. Most modern rifles handle both, but check your manufacturer's guidance.
Rifles chambered in 7.62x51 include the M1A, FN FAL, HK91 and many modern AR-10 platforms. Brass-cased ammo is ideal for reloading and long-range practice.
