The Winchester Waterfowl Bismuth 12 Gauge 3-inch 1-3/8 oz #1 Shot 25-round box is a premium, high-velocity non-toxic shotshell engineered specifically for harvesting large ducks, high-flying geese, and late-season sea ducks. A primary friction point when hunting in federally regulated wetlands is the mandatory use of non-toxic alternatives to traditional lead shot. Standard steel pellets are inherently light and low in density, which causes them to shed velocity rapidly downrange and lack the crushing kinetic energy needed for clean, ethical harvests at extended distances. Winchester completely overcomes this environmental bottleneck by loading premium, tin-plated bismuth shot that matches the density and terminal impact of lead without damaging your shotgun.
The technical advantage focuses on protecting pellet roundness under intense magnum ignition forces to ensure maximum downrange pattern concentration. Launching its heavy 1-3/8 oz payload of #1 shot at a blistering muzzle velocity of 1,450 FPS, this waterfowl load delivers devastating downrange energy. Mechanically, conventional non-toxic loads suffer from pellet deformation during firing, leading to patchy patterns and erratic flyers. Winchester prevents this by packing the shot column with a micro-granular synthetic buffering compound that cushions the pellets. This buffered payload works alongside the signature Drylok wad system, utilizing a two-piece double gas seal to manage internal pressures and deliver up to a 90% pattern concentration at 40 yards.
Slinging its 1-3/8 oz bismuth payload at 1,450 FPS, this magnum cartridge is built to deliver absolute reliability in freezing downpours and damp coastal blinds. Unlike ultra-hard steel shot which can score chokes and damage older barrels, bismuth metal is highly ductile and soft, making it 100% safe to fire through modern choke profiles and classic vintage fixed-choke shotguns alike. Assembled with water-resistant lacquered primers and moisture-blocking hulls, this premium waterfowl load ensures positive ignition and smooth feeding through semi-automatics, pump-actions, and traditional break-open shotguns when conditions afield are at their worst.
Key Benefits
- Premium Tin-Plated Bismuth Payloads: 22% greater density than standard steel delivers lead-like kinetic energy and velocity retention at long range.
- Synthetic Granular Buffering Compound: Fills the empty spaces inside the hull to cushion pellets against ignition forces and preserve spherical geometry.
- Two-Piece Drylok Wad System: Creates an optimized double gas seal that maximizes pressure efficiency while completely locking out external moisture.
- Soft Ductile Pellet Metallurgy: Eliminates the risk of bore scoring or choke damage, ensuring complete safety in classic vintage shotgun barrels.
