Description
If you shoot a .303 British, Winchester Super-X has been a reliable choice since 1922. This load pairs the classic .303 British cartridge with a 180-grain Power-Point bullet, which is the weight most folks go to for this caliber when hunting bigger game.
The Power-Point bullet design is straightforward and effective. It features a soft tip with a copper jacket that expands when it hits game, with strategic notching around the jacket mouth to ensure consistent expansion. The exposed soft nose does the work, while an alloyed lead core gives you good weight retention and deeper penetration. You're getting about 2460 feet per second at the muzzle and 2418 foot-pounds of energy, which puts this solidly in medium-to-large game territory.
What Makes Winchester Super-X Stand Out
Winchester Power-Point ammunition has earned its reputation through real-world results. The design is proven, the brass is quality, and these rounds are loaded with consistency you can count on. For the .303 British especially, where ammunition options can be more limited, Winchester Super-X represents a reliable mainstream option that works. The brass cases are reloadable too, so you can stretch the value if you reload.
Built for Hunting Applications
This is ammunition made for hunting, not casual plinking. The 180-grain soft point is the right choice for .303 British hunting loads. You'll find this weight and bullet type across most quality .303 British ammunition lines because it works. The ballistics are matched well to typical .303 British rifle capabilities, giving you practical knockdown power at the distances most hunters actually shoot.
