HEVI-Shot HS15504 HEVI-Bismuth Waterfowl 10 Gauge 3.5" 1 3/4 oz #4 Shot - 25 Rounds/Box, 10 Boxes/Case

HEVI-Shot HS15504 HEVI-Bismuth waterfowl ammunition delivers a non-toxic alternative built for serious 10 gauge duck and goose hunters. Loaded with bismuth shot instead of lead or steel, these 3.5" magnum shells pack 1 3/4 oz of #4 shot in a 25-round box format—giving you the density and performance you need for long-range water bird hunting without the regulatory restrictions of traditional lead loads. Each case contains 10 boxes, making it an economical choice for the dedicated waterfowler who shoots regularly.

Bismuth shot bridges the gap between lead's ballistics and steel's limitations. Unlike steel, bismuth doesn't require the velocity bump or tighter chokes to perform, and it patterns more like lead than many shooters expect. For hunters in non-toxic-shot zones or those who simply prefer to hunt responsibly, HEVI-Bismuth rounds let you use your existing shotgun and choke tubes without compromise—no need for specialized equipment or barrel treatments.

The 3.5" 10 gauge format is purpose-built for big-water situations where reach and payload matter. Whether you're hunting coastal bays, large reservoirs, or anywhere distance to the birds demands extra pellet energy, this load gives you the authority to take birds cleanly at the ranges where 12 gauge shells fall short. For the hunter serious enough to shoot a 10 gauge, HEVI-Shot's bismuth formulation respects both your investment in the gun and your commitment to ethical, legal waterfowl hunting.

Frequently Asked Questions

Will HEVI-Bismuth work in my standard 10 gauge shotgun?

Yes. Bismuth shot does not require special barrels, choke tubes, or modifications. You can use your existing 10 gauge shotgun and factory chokes with these loads.

What's the difference between bismuth and steel shot for waterfowl?

Bismuth shot is denser than steel and closer to lead's ballistic performance, so it patterns more predictably and cleanly without requiring tighter chokes or higher velocity. It's a good middle ground for hunters in non-toxic ammunition zones.

Is this ammunition legal for waterfowl hunting?

Bismuth is a non-toxic shot material and complies with non-lead ammunition regulations in all U.S. waterfowl hunting zones. Always verify your state and local regulations for any additional requirements.

What game is #4 shot best for?

HEVI-Bismuth #4 shot is designed and optimized for ducks and geese, particularly at longer distances where the 3.5" 10 gauge magnum shell delivers maximum range and energy.
