The Winchester Double X 12 gauge buckshot delivers 9 copper-plated #00 buck pellets at 1450 feet per second from a 2-3/4″ shell, making it a go-to load for big game hunting and home defense applications. Winchester Double X 12 gauge buckshot combines copper-plated lead shot with reloadable hulls and non-corrosive Boxer primers for reliable, repeatable performance in smooth-bore shotguns. A 12 gauge buckshot shell is a shotshell loaded with multiple large-diameter pellets designed for close- to mid-range engagement of large targets, where pattern density and stopping power are paramount.
Performance at a Glance
The copper plating on each #00 buck pellet reduces lead fouling and maintains round geometry during barrel transit, which contributes to tighter patterns downrange. At 1450 fps, this load generates substantial energy transfer on target, and the 9-pellet count provides adequate pattern coverage for deer-sized game within effective buckshot range. Winchester manufactures this ammunition in the United States using domestically sourced components and quality-control protocols refined over decades of commercial production.
