The .300 Winchester Short Magnum is a 7.62mm short action magnum cartridge with considerable effect. It is very similiar to the regular .300 Winchester Magnum in terms of ballistics, but takes advantage of the short action design which allows more powder to sit closer to the flash hole. When the primer ignites, it allows a more uniform burn which in turn translates into more efficient use of energy. A 300 WSM can therefore achieve the same ballistics with less powder.

Oryx means good accuracy, massive mushrooming and high residual weight. This bonded design suits the all-round hunter who wishes to simplify the choice of cartridge for hunting. Oryx is available in most calibres from 222 Remington to 375 H&H Magnum. Thanks to its excellent performance, in a very few years Oryx has become the most popular of the Norma bullets.
