Win Bioammo 12ga 2.75" #7.5 25/250

Winchester BioAmmo 12-gauge shotshell ammunition represents a practical choice for shooters looking to reduce their environmental footprint without sacrificing field performance. Built with bio-polymer components derived from sugarcane-based materials instead of traditional petroleum plastics, these 2.75" shells deliver the ballistic reliability Winchester is known for while using sustainably sourced components. Each round fires a 7/8 oz. charge of #7.5 lead shot, making it well-suited for clay target sports, upland game, and general shooting applications where this shot size performs.

The engineering here is straightforward: low-brass casings paired with a four-petal, one-piece cushioned wad that handles recoil and protects patterns. The bio-polymer materials used—including the case and wad—are certified compostable, though they don't meet the accelerated industrial composting timeline. What matters on the range and in the field is that these shells pattern like standard ammunition while the materials break down naturally into biomass, water, and CO2 when left in the environment. It's the kind of responsible ammunition choice that doesn't ask you to compromise on what you're shooting.

This 25-round box (250 rounds per case) works for anyone running a standard 12-gauge: hunters, trap shooters, clay busters, or folks who simply want ammunition that aligns with their values. The #7.5 shot size delivers effective patterns for most upland birds and clay targets, making BioAmmo a versatile, eco-conscious load that handles typical shotgun use without the guilt.

Key Features

• Bio-polymer components made from sugarcane-based materials reduce petroleum plastic use
• Certified compostable case and wad that eventually biodegrade into biomass, water, and CO2
• Four-petal one-piece cushioned wad for recoil management and pattern consistency
• 7/8 oz. #7.5 lead shot charge in standard 2.75" 12-gauge format
• Low-brass construction for reliability across standard 12-gauge shotguns

Frequently Asked Questions

What is BioAmmo and how is it different from standard shotshell ammunition?

BioAmmo uses bio-polymer components made from sugarcane-based materials instead of traditional petroleum-based plastics for the shell case and wad. The components are certified as compostable—meaning they'll eventually break down into biomass, water, and CO2 in the environment. Ballistically, they perform like conventional shotshells.

Will BioAmmo work in my 12-gauge shotgun?

Yes. These are standard 12-gauge 2.75" shells designed to function in any shotgun chambered for 12-gauge 2.75" ammunition. The low-brass construction and dimensions match conventional loads.

What is #7.5 shot used for?

The #7.5 shot size is commonly used for clay target shooting, trap and skeet, and upland game birds. It offers a good balance of pattern density and energy for these applications.

Are these shells certified for industrial composting?

The components are certified compostable but are not certified as OK Compost-Industrial because their thickness exceeds the timeline required for industrial composting certification. However, when left in the environment, they will eventually degrade into biomass, water, and CO2.
