Description
Winchester Double X loads bring the power and precision you need for hunting situations. These 3-inch shells pack 12 copper-plated 00 buck pellets moving downrange at 1450 fps, giving you the velocity and payload that make a difference when accuracy counts. The copper plating combined with buffering material works to keep your pellets in a uniform, tight pattern as they leave the barrel, which means more consistent energy delivery where it matters.
Winchester Double X 3 Inch Copper-Plated Construction
The buffered design is what sets Double X apart from basic buckshot loads. That composite buffer powder fills the spaces between pellets inside the shell, protecting them during the firing process. When the shot exits your barrel, the pellets maintain their spherical shape better than unbuffered loads, translating to better downrange performance and tighter groupings on target. Copper plating over the lead also adds hardness, which reduces deformation on impact and extends your effective range.
Double X High-Velocity Performance
At 1450 fps, these shells deliver the energy needed for medium-sized game at reasonable hunting distances. The combination of velocity and pellet count gives you multiple projectiles working together, improving your odds of solid placement. Whether you're using an 870 pump, an autoloader, or a break-action gun, Winchester Double X feeds and cycles reliably in a wide range of shotguns.
Built for Field Use
These are straightforward, practical shells designed for real-world hunting. You get 5 rounds per box, which means you're getting ammunition built specifically for the moments when consistency and power matter. The shells are boxer primed, non-corrosive, and reloadable if you go that route. Double X has earned trust with generations of hunters who need ammunition that performs every single time.

Frequently Asked Questions
What makes the buffering in Winchester Double X 00 buckshot important?
The composite buffer material fills spaces between pellets inside the shell, protecting them during firing. When the shot exits the barrel, the pellets stay in their original spherical shape better than unbuffered loads, which creates tighter patterns downrange and more consistent performance on target.
Will Winchester Double X 3 inch shells work in my shotgun?
These shells are designed for shotguns chambered for 3 inch magnums. Check your shotgun's barrel or manual to confirm it's rated for 3 inch shells. Winchester Double X loads feed and function reliably in pump actions, autoloaders, and break-action guns.
How far can you shoot Winchester Double X 00 buckshot effectively?
Most hunters keep buckshot shots at 40 yards or less for reliable patterns and energy. The key is pattern testing your specific shotgun with this load to see where it groups. Choke, gun type, and individual shotgun variations all affect how these shells pattern.
Is Winchester Double X copper-plated buckshot reloadable?
Yes, these shells use boxer primers and are reloadable. The copper plating and hardness of the pellets make them suitable for reloading if you want to reduce long-term costs.
