9mm Winchester Magnum

Winchester Magnum

Winchester Magnum refers to a "family" of cartridges developed by the Winchester Repeating Arms Company , one of the oldest firearms manufacturers in the United States, in the late 1950's and early 1960's, all based on the same basic cartridge case. The basic case was a "short" magnum, meaning it would work through a standard (i.e.; .30-06) length rifle action rather than requiring the longer, magnum (i.e. .375 Holland and Holland) actions.

Dimensions

The dimensions of the basic case are:

Winchester Magnum case dimensions
Outside diameter (at base) .532 in. (13.51 mm)
Inside diameter (of case) .490 in. (12.47 mm)
Maximum case length 2.62 in. (66.55 mm)

Originally known as a "short" magnum as compared to the .375 H&H Magnum, this is now considered the "long" magnum since the development of the family of Winchester Short Magnums.

Cartridge list

The cartridges in this family are, in the order of development:

With the exception of the .264, all of these cartridges are still widely used. The .458 has become the #1 cartridge for dangerous game in Africa, as well as a very popular round with Alaskan/Canadian bear guides. The .338 is widely used for game ranging from elk and African plains game to dangerous game such as grizzly/brown bears and African lions. The .300 is one of the most popular cartridges in the world, used for everything from deer to brown bears.
