The Winchester Super-X .243 Winchester in 80-grain Jacketed Soft Point (JSP) is a versatile, high-speed load designed for the hunter who needs a dual-purpose round. While the 100-grain loads are the standard for deer, this 80-grain speedster offers a flatter trajectory and more explosive terminal performance, making it the premier choice for large varmints, long-range predators, and smaller-bodied deer or pronghorn. The Super-X 80gr JSP is an efficiency specialist. With a Ballistic Coefficient of 0.244 (G1), the bullet is optimized for maximum speed and rapid fragmentation/expansion. At 3,350 fps, it delivers nearly 2,000 ft-lbs of muzzle energy. The Soft Point design is inherently more rugged than a hollow point, ensuring it doesn't splash on the surface but instead drives in far enough to reach the vitals before fully expanding. Whether you're calling coyotes in the open plains or hunting pronghorn in the sagebrush, the Winchester Super-X .243 Win 80gr JSP provides the high-velocity performance you need to stay on top of the food chain.
