.300 Win Short Mag Ammo

The .300 Winchester Short Magnum (.300 Win Short Mag or .300 WSM) is a high-performance, short-action rifle cartridge introduced by Winchester in 2001. Designed to provide near-magnum level performance in a compact, efficient package, the .300 WSM has gained popularity among hunters and long-range shooters who require a powerful and versatile cartridge that can be chambered in short-action rifles.


The .300 WSM features a short, fat bottleneck case with a rebated rim, which allows for a large powder capacity and efficient combustion, resulting in high velocities and consistent performance. The cartridge typically accommodates bullet weights ranging from 150 to 210 grains, with muzzle velocities between 2,900 and 3,300 feet per second, depending on the bullet weight and powder charge.

One of the main advantages of the .300 WSM is its ability to provide near-magnum level performance in a compact, short-action rifle platform. This allows for faster cycling, potentially lighter rifle weight, and a more convenient overall package. The cartridge delivers a flat trajectory, excellent accuracy, and impressive energy retention, making it suitable for hunting a wide range of game, from medium-sized animals like deer and antelope to larger species such as elk and moose, at various distances.

The .300 Winchester Short Magnum is an excellent choice for hunters and shooters who want a powerful, versatile cartridge that can be used in a short-action rifle without sacrificing performance. Its combination of compact design, impressive ballistics, and broad hunting applications make the .300 WSM a popular and effective choice for those seeking an efficient and high-performing hunting cartridge.
