Winchester Ammo X243WSS Super X243 WSSM 100 gr 3110 fps Power-Point (PP) 20 Bx/10 Cs

The Winchester Super X 243 WSSM is a high-velocity centerfire rifle round built for hunters who demand speed and consistent accuracy. This 100-grain Power-Point load leaves the muzzle at 3110 fps, delivering the kind of flat trajectory and impact energy that works across medium-game hunting scenarios. Winchester's Super-X line has been a backbone of American hunting ammunition for generations—refined over decades with modern manufacturing to pair reliable performance with practical value.

The 243 WSSM (Winchester Short Magnum) is a legitimate magnum-class cartridge in a compact case, meaning you get serious velocity without excessive recoil or the need for a full-length action. The Power-Point bullet design is engineered for rapid, controlled expansion on impact, which translates to effective energy transfer whether you're hunting deer, antelope, or similarly-sized game at varying ranges. This is not boutique ammunition—it's the kind of round serious hunters keep in their magazines because it works and because they can afford to shoot it regularly enough to stay proficient.

Each box contains 20 rounds, and Winchester packages them 10 boxes per case, making it convenient to stock up for the season or maintain a reliable supply for your 243 WSSM rifle. If your rifle is chambered in this cartridge, this load offers a straightforward choice: proven Winchester quality at a reasonable cost, with enough velocity and bullet performance to handle real hunting situations.
