243 Winchester Super Short Magnum
(WSSM) Rifle Cartridge

Abbreviated Name:  243 WSSM

 
 

TECHNICAL INFORMATION:

The 243 WSSM uses a shortened 300 Winchester Short Magnum case necked down to accept a .243” / 6mm diameter bullet. Due to the extremely high velocities achievable with this cartridge, shortened barrel life can result depending on your load. Loaded with heavier bullets and/or at lower velocities, barrel life can be very acceptable if your barrel is well cared for. These concerns are no different than for other high-velocity cartridges. Full length sizing may be needed to eliminate tight chambering due to thickness of brass and steep shoulder angle.
