Win Bismuth 20ga 3" #4 15/150

Winchester Bismuth 20ga 3" #4 15 Rounds per Box ammunition delivers non-toxic, premium performance for waterfowl hunters and tactical shooters who demand reliable, environmentally responsible shotshell loads. This ammunition is engineered for shooters who cannot use traditional lead shot due to regulatory restrictions or personal preference, yet refuse to compromise on pattern density, shot uniformity, or downrange energy. Bismuth shot has become the standard for serious hunters in steel-shot-only zones and offers superior ballistic characteristics compared to steel alternatives.

The Winchester Bismuth load features tin-plated bismuth shot that maintains exceptional roundness and uniform diameter throughout each shell, critical for consistent patterning and tight shot clusters at distance. Winchester's proprietary buffering compound fills voids within the shotshell column, cushioning individual pellets during acceleration and preventing deformation—a key factor in maintaining pattern integrity that separates premium bismuth loads from budget alternatives. The 3-inch magnum case delivers #4 shot, a versatile pellet size ideal for medium-range waterfowl work and tactical applications requiring controlled spread and penetration without excessive pellet count degradation.

This load performs optimally in 20-gauge shotguns rated for 3-inch magnum shells and benefits shooters who operate in lead-restricted environments or prefer non-toxic ammunition for all field work. Law enforcement and wildlife professionals favor bismuth for its superior pattern consistency compared to steel, reducing the number of pellets required to achieve reliable terminal performance. The 1.38 lb box weight represents a standard 15-round loading, making it practical for training sessions, competitive shooting, or extended hunting trips where reliability and regulatory compliance cannot be negotiated.
