7.7x56mm R (.303 British)

The inclusion of the .303 British in my list of sniping calibers is based solely on its historical significance. As far as I know there are no current sniper rifles chambered in the legendary .303. The reason is simply because the .308 (7.62x51 NATO) out performs the .303 in every aspect. The .303 saw extensive action in WWI and WWII as a sniping round, especially in the Enfield No 4 Mk1 (T). This rifle/ammo combination was an exceptional performer, and served the British troops until well after WWII, when the L42A1 was adopted. There are still plenty of these old rifles out there and they can usually be purchased very cheaply.
