History of the .300 Winchester Short Magnum Cartridge:
The .300 Winchester Short Magnum Cartridge or .300 WSM for short was one of the 7 WSSM & WSM cartridges introduce in the early 2000’s (app. 2003).
History of the Winchester’s Super Short and Short Magnum Cartridges:
Winchester came out with the 7 new cartridges known as the WSSM (Winchester Super Short Magnum) in .223″, .243″ and .25″ calibers and the WSM (Winchester Short Magnums) in 7mm, .270″ ,.300″ and .325″.
Basically, Winchester took the idea from the Lazzeroni Company with a slightly steeper shoulder angle, and later Remington followed with their line of short, fat cartridges .
Winchester also produced the rifles in all 7 calibers, then a few years down the road stopped making the ammunition to the dismay of all the rifle  owners.
Now it seems to be back in stock and other ammunition producers are also making the ammunition again.
