300 WSM

Short Action. Serious Reach.

The .300 Winchester Short Magnum was designed to excel at one thing: propelling .30-caliber bullets quickly and accurately from a short-action rifle. No gimmicks, just real magnum performance in a more compact package. 300 WSM ammo earned its reputation in the field, where shots stretch past the treeline, and wind starts to matter. It delivers the velocity, energy, and consistency hunters expect without needing a long, heavy rifle.

Why Choose 300 WSM Ammo

Hunters didn’t adopt .300 WSM by accident. Here’s why it’s still a favourite:

  • Short-action advantage: Designed for short-action rifles, which often means a lighter, better-balanced hunting setup.
  • Flat shooting: High velocity helps flatten the trajectory and reduce wind drift at longer distances.
  • Field-proven performance: 300 WSM has been putting animals in the freezer for years, especially in open country where range matters.
  • Efficient power: You get magnum-level performance without the extra length and weight of a traditional magnum action.

Choosing the Right 300 WSM Load

For deer and similar-sized animals:

A mid-weight, controlled-expansion bullet offers a strong balance of accuracy, energy, and manageable recoil.

Bullet construction matters more than speed. Choose a design that holds together and penetrates and focus on shot placement.

For longer shots:

Velocity helps, but consistency matters more. Know your rifle, confirm your zero, and respect your limits.
