The .325 WIN Ammo Short Magnum, commonly known as the 325 WSM is an 8mm caliber rebated rim bottlenecked centerfire short magnum medium bore cartridge. Winchester Ammunition introduced the round in 2005.
The name of the cartridge is a misnomer as the bullet diameter is .323 in (8.2 mm). Introduced at the 2005 Shot Show in Las Vegas, NV, it is the largest member of the Winchester Short Magnum family of cartridges.
The .325 WIN Ammunition was intended for the hunting of medium and large-bodied thin-skinned dangerous and non-dangerous big game animals of Africa, Asia, Europe, and North America.
Winchester factory loads for the .325 WSM include a 180-grain Ballistic Silvertip bullet and a 200-grain Accu-Bond bullet in their premium Supreme ammunition line. In their standard Super-X range, they offer a 220 grain PowerPoint bullet.
