300 WSM Centerfire Ammunition

300 Winchester Short Magnum (also known as 300 WSM) is a .30 caliber rebated rim bottlenecked centerfire short magnum cartridge that was introduced in 2001 by Winchester.

The .300 WSM is adequate for hunting all big game including (but not limited to): moose, black bear, brown bear, elk, mule deer, and white-tailed deer in forests and plains where long range, flat shots are necessary. The .300 WSM is also used in bench-rest shooting.

It has a standard bullet diameter of .308 or 7.62mm and takes advantage of the numerous bullet options available in that caliber.
