308 Win Brass (Large Rifle primer)
.308 Winchester, .308, 7.62mm Nato, 7.62x51mm

2.002 - 2.009 O.A.L.
The venerable .308 Winchester has made quite a name for itself since it was first introduced in 1952. The .308 and its military equivalent, the 7.62x51mm Nato, is a very efficient cartridge that has excellent ballistics, while still being fairly easy on the shoulder. That, and its inherent accuracy have kept it thriving as both a competition and hunting caliber.
