Winchester Super X 100Th Anniversary F

Winchester is celebrating the 100th anniversary of its popular Super-X brand of ammunition. Since 1921, Super-X has been a trusted and proven element of Winchester Ammunition's lineup of products, giving hunters and sport shooters a dedicated, dependable load for rifles and shotguns. On its centenary, Winchester will offer seven cartridge options packaged in retro-styled boxes.

“Winchester is a brand that represents both legacy and innovation,” said Matt Campbell, vice president of marketing and sales. “For more than 150 years, Winchester has been a leader in innovation with brands like Super-X, which fundamentally changed the ammunition landscape when it was introduced. That continuous innovation is part of the Winchester story and continues today.”

Available options in the Winchester 100th anniversary Super-X lineup will include 30-30 Win., .270 Win., .243 Win., .308 Win., .22 Long Rifle and two 12-ga. options. The .30-30, .270 and .308 loads are topped with a 150-gr. Power-Point bullet, while the .243 Win. is loaded with a 100-gr. Power-Point bullet. The .22 Long Rifle offering will include a 40-gr. Power-Point projectile. The two 12-ga. options are both 2 3/4" shells, one loaded with No. 6 shot and the other loaded with 00 buck.

Winchester President and Owner John Olin developed the concept of Super-X in the early 20th century, theorizing that progressive burning powders could produce greater velocities and more energy without creating significant pressure spikes. While the concept is commonly used in ammunition today, the idea was revolutionary back in the 1910s and '20s, and Winchester's offering of Super-X ammunition loaded with progressive burning powder made it dramatically more powerful than ammunition loaded with conventional smokeless powders of the time.
