HEVI-Shot HEVI-Hammer 12 gauge 3.5" waterfowl ammo splits the difference between pure bismuth loads and traditional steel: you get a layered payload of HEVI-Bismuth pellets over steel shot, engineered to deliver more lethal range and tighter patterns without the premium cost of all-bismuth rounds. If you're chasing ducks and geese and want better reach than straight steel but don't want to break the bank, this is the load to pattern through your gun.
The ballistics story here is straightforward. HEVI-Shot loads the top 15 percent of the payload with 9.6 g/cc HEVI-Bismuth pellets—a denser, harder-hitting alloy—then fills the remaining 85 percent with precision steel shot cast in Sweet Home, Oregon. That layering approach extends effective range and compresses shot patterns compared to steel alone, meaning cleaner, more reliable kills at distance. The #4 shot in this load hits the sweet spot for most waterfowl hunting, offering a good balance of pellet count and knockdown power.
Each box contains 25 rounds loaded to standard 3.5" pressure, and the case holds 10 boxes, making this a practical choice for serious waterfowl hunters who shoot volume. Whether you're working over decoys on a river or pass-shooting in cold weather, HEVI-Hammer ammunition performs when conditions are tough.

Frequently Asked Questions
Will HEVI-Hammer work in my standard 12 gauge shotgun?
Yes, HEVI-Hammer is loaded to standard 3.5" magnum specifications and will function in any 12 gauge shotgun rated for 3.5" shells. Always verify your gun's chamber length before shooting.
How does HEVI-Hammer compare to pure steel or bismuth waterfowl ammo?
HEVI-Hammer blends the cost efficiency of steel with the ballistic advantage of bismuth by layering 15% HEVI-Bismuth pellets over 85% steel shot. This gives you more range and pattern density than straight steel while keeping your cost lower than all-bismuth loads.
Is #4 shot the right choice for my waterfowl hunting?
The #4 shot size in this load is a proven option for ducks and geese and works well for most waterfowl hunting situations. Final shot selection depends on your target, range, and local regulations—consult your state's waterfowl hunting guide for any restrictions.
