.243 Winchester Super Short Mag (WSSM) in 100 Grain Soft Point- Hard to find, but we have you covered!!
The .243 Winchester Super Short Magnum or .243 WSSM is a rifle cartridge introduced in 2003. It uses a .300 WSM (Winchester Short Magnum) case shortened and necked down to accept a .243 in/6mm diameter bullet, and is a high velocity round based on ballistics design philosophies that are intended to produce a high level of efficiency. The correct name for the cartridge, as listed by the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI), is 243 WSSM, without a decimal point. This cartridge is used for small game such as varmints and for animals as large as deer.
Choice Ammunition loads the .243 WSSM with the same 100% hand-loading techniques as our other calibers. Our loading techniques and extremely tight tolerances are only matched by passionate hand-loaders in their own loading rooms. Our consistencies box to box and lot to lot, are created by continuous testing at the range- adjusting varied powder and brass lot formulas to match exact velocities and points of impact as the last time we loaded this caliber. Exact seating depths and our proprietary load formulas produce a round of ammunition you can count on for accuracy and dependability each and every time- and at that critical moment in the field when it all comes down to the shot!
The Bullet:

The Hornady InterLock is designed to be a devastating hunting bullet and nothing less. The InterLock Ring – a Hornady exclusive – ensures that the core and jacket remain locked during expansion. The InterLock retains more mass, energy and momentum after impact and transfers that energy to the target. Its reliable stopping power has earned the InterLock a worldwide reputation as a bullet for serious hunters.
