300 Winchester Short Magnum

 

              300 Winchester Short Magnum Ammo

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

 

                           Specifications.

The advantage to this round is ballistic performance nearly identical to the .300 WSM in a lighter rifle with a shorter action burning 8 – 10% less gunpowder. A disadvantage of cartridge case designs with relatively large case head diameters lies in relatively high bolt thrust levels exerted on the locking mechanism of the employed firearm. Also, in small ring actions the larger chamber diameter removes more steel from the barrel tenon, making it weaker radially.

 

                                    Use

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 benchrest shooting.The .300 WSM  has a standard bullet diameter of .308 in (7.82 mm) and takes advantage of the numerous bullet options available in that caliber.

 

                                        Warnings

300 WSM is a Delta L problem cartridge, meaning it can present unexpected chambering and/or feeding problems. The Delta L problem article explains this problem in more detail. The .300 Remington Short Action Ultra Magnum has very similar cartridge dimensions but is not interchangeable.
