The .243 Winchester Short Magnum (WSSM) is a powerful and highly accurate centerfire rifle cartridge based on the .300 WSM case necked down to accept .243 caliber (6mm) bullets. Developed in 2006 by Winchester, this round offers good velocities with minimal recoil - making it perfect for smaller framed shooters.The .243 WSSM is primarily used for hunting medium sized game such as deer, antelope and wild boar at extended ranges due to its flat trajectory and low recoil. It can also be used effectively for shooting varmints such as coyotes, foxes and prairie dogs, making it a great all-around choice for many hunting applications.
