About .300 WSM Ammunition

The .300 WSM (Winchester Short Magnum) is a powerful short-action magnum cartridge designed to deliver exceptional performance in a compact package. Introduced by Winchester in 2001, the .300 WSM was developed as part of the Short Magnum family, based on a shortened and rebated rimless case that provides magnum ballistics while fitting in standard-length actions. The .300 WSM is highly regarded for big game hunting and long-range shooting due to its impressive velocity, flat trajectory, and effective performance on large game animals at extended distances.

Types of .300 WSM Loadings

  • Polymer Tip: Polymer tip projectiles can be common on a variety of loadings across many calibers. Typically, polymer tips accompany a hollow, open pocket which sits below the tip in the projectile. On impact, some polymer tip loadings are designed to expand as the tip presses back against the lead core. Polymer tips are also often utilized to achieve higher velocities and provide better ballistic capabilities to some cartridges. Many calibers which were limited to flat point and round nose style loadings have been granted better velocity due to polymer tips.

Firearms that Use .300 WSM Ammo
