300 WSM Ammo

300 Winchester Short Magnum (WSM) ammo was introduced in 2001 and would become the first cartridge in Winchester’s short magnum line of bottlenecked centerfire rounds. The 300 WSM is similar to it’s older brother the 300 Winchester magnum, but can be chambered in a short action rifle that is often a much lighter rifle.

The weight of the 300 WSM is a distinct advantage when hunting in the high mountains or across the Texas hill country. A lighter rifle is a blessing over rough territory, but big game needs a big round so the 300 WSM is an excellent compromise. The 300 Winchester short mag can be an absolutely devastating round to medium and large game commonly hunted in North America.

The round is very powerful and very capable. The caliber fills the role of a guide gun quite well, its power can be counted on for defense against animals, or as a humane secondary shot should the primary bullet only wound your target. Take a look at our in-stock 300 WSM ammo for sale below:
