Overview of 300 WSM Ammo
300 WSM (Winchester Short Magnum) delivers near-300 Win Mag performance from a short, fat case that fits a short-action rifle. It fires a .308-inch bullet, usually 150 to 200 grains, at around 2,900 to 3,250 fps. That makes it a flat-shooting, hard-hitting choice for elk, moose, and big deer at long range, in a lighter, handier rifle than a long-action magnum.
For a long-action alternative with wider ammo selection, see our 300 Win Mag ammo. For a modern long-range magnum, see 300 PRC.

Frequently Asked Questions
300 WSM vs 300 Win Mag: what is the difference?
300 Win Mag uses a longer belted case in a long-action rifle and is slightly faster with heavy bullets. 300 WSM uses a short, fat, beltless case in a short-action rifle, giving similar performance with standard hunting weights in a lighter, handier gun. 300 Win Mag ammunition is more widely available.
Is 300 WSM good for elk?
Yes. 300 WSM is an excellent elk cartridge, with enough energy for ethical shots well past 400 yards with a quality bullet like the Hornady 200gr ELD-X or Federal Fusion 180gr. Practice with your hunting load and know your effective range.
Can I shoot 300 WSM in a 300 Win Mag rifle?
No. 300 WSM and 300 Win Mag have completely different case shapes and lengths. They are not interchangeable. Only fire 300 WSM in a rifle chambered for 300 WSM.
More About 300 WSM Ammo
Winchester and Browning introduced the 300 WSM in 2001, kicking off the short magnum craze of the early 2000s. The idea was simple: a short, wide powder column burns efficiently, so a short-action case could match much of the performance of longer belted magnums.
The 300 WSM quickly became the most successful of the short magnums, adopted by hunters who wanted magnum power in a lighter, faster-handling rifle. While newer cartridges like the 300 PRC have taken over the long-range spotlight, the 300 WSM remains a proven elk and big-game round with a loyal following.
