About the 300 Winchester Short Magnum
The cartridge overall length is 72.64 mm, cartridge case is 53.34 mm in length and the bullet diameter is .308 in (7.62 mm), which is common to all U.S. .30 caliber cartridges. The principle at work in the short magnum cartridge is the advantage of fitting larger volumes of powder in closer proximity to the primer's flash hole, resulting in more uniform, consistent ignition.
The advantage to this round is the ballistics are nearly identical to the .300 Winchester Magnum, but in a lighter rifle with a shorter action. 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 in a radial direction .
