The .223 Winchester Super Short Magnum Cartridge or .223 WSSM (for short) was one of the 3 WSSM & 4 WSM cartridges introduce in the early 2000’s (app. 2003).
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.
