About the Manufacturer
The company who brought to life "the Gun that Won the West" is the same company who today continues to supply sportsmen with the best sporting ammunition in the world.Founded in 1866, Winchester is one of the world's most widely recognized and respected brand names.
For more than 140 years, the name "Winchester" has come to mean many things to many people. To most folks it means ammunition and the Gun that Won the West. For many others, however, it also rekindles images of fine hand tools and cutlery, fishing tackle, the classic artwork and hunting traditions.
To encourage the preservation of wildlife habitat, Winchester is a major sponsor of conservation organizations such as Ducks Unlimited and Quail Unlimited. And it's a major backer of sporting clays and other clay target shooting games.

About the 270 Winchester Short Magnum
The 270 WSM is the only cartridge of the WSM family that produces notable ballistic gains over other existing cartridges. The .300 WSM closely mimics the long popular .300 Winchester Magnum, while the 7mm WSM lags slightly behind the common 7mm Remington Magnum in terms of performance. The .325 WSM is in a league of its own in North America as the 8 mm caliber has not become commonplace.
The 270 WSM comes quite close in performance to that of the legendary .270 Weatherby Magnum. Except that the WSM is chambered in a short action and usually sports a 22" to 24" barrel where the Weatherby is usually chambered in rifles with a 26" barrel.
