Winchester BioAmmo 12ga 2.75" #6 shot shells bring a responsible approach to upland hunting and clay sports without sacrificing performance. Built with fully bio-compostable wads and cases, these shotgun rounds are engineered for shooters working sensitive wetland habitats, riparian zones, and areas where lead or traditional shot poses environmental concerns. You get the ballistics and pattern consistency you expect from Winchester, paired with components designed to break down naturally without contaminating groundwater or soil.
The #6 shot size makes these rounds well-suited for upland game birds and clay target work where precision patterning matters. Each box contains 25 rounds, and the 2.75" hull is the standard length for most modern 12-gauge shotguns. If you're serious about hunting or shooting in protected watersheds—or simply want ammunition that performs without the environmental footprint of traditional loads—these cartridges deliver on both counts.
Whether you're a clay competitor, a wing shooter in ecologically sensitive country, or someone who believes gear choices should reflect conservation values, Winchester BioAmmo offers a practical middle ground: genuine performance and reliability in a package built to minimize impact on the landscape you hunt.
