Since 1921, Winchester’s Super-X brand has provided hunters and sport shooters with dedicated, dependable loads for rifles and shotguns. To commemorate its centenary, Winchester is offering seven cartridge options packaged in retro-style boxes, such as the 12-ga. load shown above.

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 more powerful than ammunition loaded with conventional smokeless powders of the time.

Available options in the Winchester 100th anniversary Super-X lineup include: .22 Long Rifle, .243 Win., .270 Win., .30-30 Win., .308 Win. and two 12-ga. options. The .270 Win., .30-30 Win. and .308 Win. loads are topped with a 150-grain Power-Point bullet, while the .243 Win. is loaded with a 100-grain Power-Point bullet. The .22 Long Rifle offering will include a 40-grain Power-Point projectile. The two 12-gauge options are both 23/4" shells, one loaded with No. 6 shot and the other with 00 buckshot. winchester.com
