CLAYTON, MO (May 6, 2026) — Winchester Ammunition launches AutoBuck™, an all-new buckshot shotshell engineered specifically for semi-automatic shotguns.
Available in 12 gauge, AutoBuck™ is an all-purpose buckshot load designed to reliably function in semi-automatic shotguns, as well as pump action, break action, and others. With a #1 buckshot payload suitable for hunting, defense, and target shooting, AutoBuck™ is the dependable buckshot load for nearly all situations.
Key features of AutoBuck™—
- #1 buckshot – Provides excellent penetration, stopping power, and pellet count
- High pellet count – Packed with 12, #1 Buck pellets
- Ultra reliable – Optimized payload and velocities help ensure reliable functioning, even in semi-automatic shotguns
“Our engineering team went to the drawing board to develop a reliable buckshot load that fits multiple end uses and provides great value,” said Kyle Masinelli, Sr. Director Product Innovation & Strategy for Winchester. “The result is AutoBuck™. Whether you’re a competition shooter, hunter, or looking for a personal defense load, AutoBuck™ is an ideal choice.”
Traditionally, #00 buckshot is the shot size of choice due to availability and familiarity, but #1 buckshot can offer superior performance over #00 buck in many situations. The slightly smaller pellet size allows for 3 additional pellets in the payload, which improves hit probability while maintaining plenty of pellet energy and penetration.
