Winchester

Introduced by Winchester in 1925 for the Model 54 bolt action rifle, the .270 caused a flurry of controversy in shooting circles that has yet to completely die down.

People either love it or hate it. Depending upon the "expert," the .270 Winchester is either fit only for vermin or is one of the finest big game cartridges ever developed.

The intended use of the .270 at the time of its introduction was that of a long-range cartridge for use on big game. The .270 Winchester, despite some arguments to the contrary, is adequate for any North American big game, providing that proper bullets are used, with the possible exception of big bears in close quarters. Although not normally considered a varmint cartridge, the .270 Winchester does an excellent job when loaded with the lighter bullets.

The SAAMI Maximum Average Pressure for the .270 Winchester is 52,000 C.U.P.
