Win Bioammo 12ga 2.75" #4 25/250

Winchester BioAmmo 12ga 2.75" #4 Shot (25-Round Box, 250-Round Case) represents a next-generation approach to shotgun ammunition that delivers premium ballistic performance without the environmental footprint of conventional petroleum-based loads. This ammunition is manufactured by BioAmmo in Segovia, Spain, using globally patented technology that substitutes sugarcane-based bio-polymer materials in place of traditional plastics in both the shot shell cartridge and wad components. The result is a 12-gauge round that meets professional ballistic standards while using certified compostable materials throughout its construction.

The 2.75-inch chamber length and #4 shot size establish this round as a versatile load suitable for medium-range shotgun applications. The #4 pellet configuration delivers adequate energy distribution and pattern density for hunting, sport shooting, and training scenarios where penetration and shot placement matter equally. By engineering the wad and hull from bio-based polymers rather than synthetic petroleum products, Winchester and BioAmmo maintain ballistic integrity while reducing the volume of non-biodegradable waste entering the ammunition supply chain—a meaningful consideration for operators and enthusiasts who conduct repetitive range training or field operations in environmentally sensitive areas.

This ammunition suits shooters who prioritize both performance and environmental responsibility. Tactical practitioners, sport shooters, hunters, and training facilities looking to reduce their ecological impact without compromising on Winchester's ballistic standards will find this product addresses a specific and growing market need. The 25-round box format allows for flexible purchasing at both individual and case (250-round) quantities, making it accessible for range days and field preparation without requiring commitment to full case lots for initial evaluation.

Winchester's commitment to ammunition innovation extends beyond stopping power to include manufacturing practices that reflect modern environmental standards. The BioAmmo platform represents a category shift within shotgun ammunition—proving that eco-conscious design and operational reliability are not competing interests but complementary ones. Shooters evaluating 12-gauge options for consistent performance and reduced environmental liability will find this Winchester load a credible alternative to conventional ammunition across hunting, sport, and professional applications.
