The .300 WSM (Winchester Short Magnum) is a cartridge developed by Winchester for use in hunting rifles. It is a high-performance round that is designed for long-range shooting and hunting. It is capable of shooting bullets weighing from 120 to 220 grains, and can achieve velocities of up to 3,400 feet per second (1,036 meters per second).

The .300 WSM is based on the .375 Winchester Short Magnum case, which has been necked down to accept a .30 caliber bullet. It is intended to be used in short-action rifles, which are characterized by having a shorter bolt travel than long-action rifles. This allows for faster cycling of the bolt, making it easier to shoot multiple shots in quick succession.

In terms of performance, the .300 WSM is similar to other .30 caliber magnum cartridges, such as the .300 Remington Ultra Magnum and the .300 RSAUM (Remington Short Action Ultra Magnum). However, it is generally considered to be more powerful than these cartridges, and may have slightly higher recoil as a result. It is typically used with a 1:10 twist rate barrel, which is suitable for stabilizing the wide range of bullet weights that can be used with this cartridge.

Overall, the .300 WSM is a high-performance cartridge that is well-suited for long-range shooting and hunting medium to large game. It offers a combination of accuracy, power, and versatility, making it a popular choice among shooters and hunters.
