The .300 Winchester Magnum is a belted, bottlenecked magnum rifle cartridge that was introduced by Winchester Repeating Arms Company in 1963. The .300 win mag rifle is a magnum cartridge designed to fit in a standard rifle action.
The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a. 30 caliber 7.62 mm bullet.
The .300 Winchester Magnum was introduced in 1963 by Winchester for use in the Model 70 rifle. The introduction of the .300 Winchester Magnum was not unforeseen; rather, its introduction was anticlimactic. Winchester developed the .300 Winchester Magnum by taking the .338 Winchester Magnum, which was introduced in 1958, and moved the shoulder forward by 4.0 millimeters (0.156 in) and lengthening it by 3.0 millimeters (0.120 in).
