History of the .243 Winchester Super Short Magnum Cartridge:
The .243 Winchester Super Short Magnum Cartridge or 243 WSSM (for short) was one of the 7 WSSM & 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, they took the idea from the Lazzeroni Company with a slightly steepershoulder angle.
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
