The new .243" short magnum cartridge debuted chambered in Winchester's Model 70 bolt action rifle. The 243 WSSM is a commercial cartridge based on the 404 jeffery cartridge case, shortening and necking down to .243" caliber and sharpening the shoulder angle to 28 degrees the new 243 WSSM cartridge has more than ample case capacity for its dual purpose use. The 243 WSSM cartridge achieves superior dual purpose performance at the factory level, providing varmint and deer hunters with a high level of .243" caliber performance. The 243 WSSM cartridge is the first dual purpose cartridge where you do not have to handload to cater your liking of this cartridge for varmint or deer, the factory offerings are good and work accurately.

 The 243 WSSM factory loadings show a velocity of 4,060 feet per second for a 55 grain bullet for varminting and this alone is an astounding velocity for any .243" caliber cartridge, thus making the bullet energy of this cartridge an easy 500 yard varminter. The 243 WSSM factory loadings show a velocity of 3,250 feet per second for a 95 grain bullet for medium sized deer hunting, thus making the bullet energy of this cartridge an easy 375 yard medium sized deer cartridge.
