.300 Winchester Magnum (7.62x67mm)

This round was developed during 1950s by Winchester in an atempt to provide huntes with flat-shooting, long-range hunting ammunition with significant striking power. Over the time this cartridge also found its way into military and law-enforcement use as a long-range sniping round, with practical ranges up to 1000-1200 meters (as opposed to 700-800 meters with most common 7.62×51 / .308 Win ammunition). Many hunting and some sniper rifles are produced for this round in many parts of the world.
