How to Choose the Best Waterfowl Ammo for Ducks & Geese

Too many waterfowl hunters clutching an empty shotgun have watched too many birds sail off because somebody trusted hype over hard truth. From ducks to geese across every flyway, the best waterfowl ammo is the ammo that kills clean, fast, and ethically in real-world conditions.

Waterfowl ammo has changed a ton in the last 10 years. Steel still fills straps, no doubt about it—but higher-density loads, especially tungsten, have completely changed what’s possible. Modern tungsten and TSS waterfowl ammo let you shoot smaller pellets, print denser patterns, and still carry bone-breaking energy well past ranges where steel runs out of gas.

Whether you’re duck hunting flooded timber at 25 yards, pass shooting late-season honkers in a north wind, or dialing in snow goose loads for spring conservation season, choosing the right waterfowl shotgun shells matters more than ever.

Key Takeaways

Tungsten waterfowl ammo at 12 g/cc is 53.8 percent denser than steel (7.8 g/cc), retaining far more energy downrange.
Higher pellet density allows smaller shot sizes to deliver equal or better lethality.
Pattern density—not raw velocity—is the real key to clean kills.
Sub-gauges like 20 gauge, 28 gauge, and even .410 are viable with modern tungsten and TSS ammo.
Always match your ammo to distance, species, and real hunting conditions.

What Is the Best Waterfowl Ammo for Ducks and Geese?

The best waterfowl ammo is a balance of pellet density, shot size, and pattern performance matched to how you actually hunt. Ducks and geese are built differently, react differently to impact, and are usually shot at different distances—and your ammo needs to reflect that.

Ducks are fast, lightly boned, and usually taken inside 40 yards. They demand pattern density more than sheer penetration. Geese are heavier, tougher, and often taken farther out, especially during the late season. They require pellets that hold energy and break bone.

Steel waterfowl ammo will still kill birds, especially over decoys. But when distances stretch, winds howl, or birds flare, tungsten waterfowl ammo flat-out performs better. The best loads cost more, but fewer cripples and longer ethical range make them worth it.

Why Pellet Density Matters More Than Velocity

Velocity sells shells. Density kills birds. Think of it like this: throw a ping-pong ball and a golf ball at the same speed. One bounces off. The other breaks bones. That’s pellet density in a nutshell.

Steel weighs about 7.8 grams per cubic centimeter. HEVI-XII tungsten weighs 12 g/cc—more than 53 percent denser. That added mass means pellets slow down less, hit harder, and penetrate deeper at distance. Smaller pellets also mean more projectiles in the air, which translates into higher pattern density and more lethal hits where it counts.

Steel vs. Tungsten vs. Bismuth for Waterfowl Hunting

Steel is affordable, legal everywhere, and effective inside 30–35 yards. Its biggest drawback is rapid energy loss beyond that range.

Bismuth is slightly denser than steel and softer, making it safe for older guns. But it can be brittle and inconsistent when pushed hard.

Tungsten-based loads—especially modern blends like HEVI’s many options—retain energy, fly truer, and pattern tighter. This advantage becomes obvious beyond 40 yards, especially on geese.

The Breakdown

Follow this chart for an easy guide when choosing between steel, bismuth and tungsten payloads.

Material	Density	Best Use Case	Limitation
Steel	7.8 g/cc	Budget hunts	Loses energy fast
Bismuth	9.6 g/cc	Older guns	Brittle
Tungsten	12 g/cc+	Long range	Cost

What Shot Size Should You Use for Ducks vs. Geese?

With steel, you’ve probably been taught to size up. With tungsten, it’s the opposite. For ducks, steel typically performs best in #2 to #4. With tungsten or TSS waterfowl ammo, #4 to #6 deliver denser patterns and cleaner kills. For geese, steel BB through #2 is common. Tungsten allows #2 through #4—and many experienced hunters run #6 with incredible results.

HEVI brand ambassador Tony Vandemore famously shoots #6 tungsten for both ducks and geese. Smaller pellets mean more hits and better penetration, and it works. Read on to learn more of his load selection tricks.

Best Waterfowl Ammo by Gauge

12-Gauge Waterfowl Ammo: The 12 gauge is the most versatile shotgun ever built. It handles wind, big spreads, and long-range work with authority. For late-season honkers and snow goose loads, the best 12-gauge waterfowl ammo paired with tungsten is hard to beat.

20-Gauge Waterfowl Ammo: Modern tungsten has turned the 20 gauge into a legitimate goose gun, with less recoil, lighter weight, and devastating performance. The best 20-gauge waterfowl ammo with tungsten makes 20 gauge goose loads extremely effectively.

28-Gauge Waterfowl Ammo: The 28 gauge is a scalpel. With tungsten waterfowl ammo, it prints unbelievably dense patterns. The best 28 gauge waterfowl ammo is deadly on ducks and ethical on geese inside reasonable ranges.

.410 Duck Loads: The .410 isn’t a toy anymore. With the best tungsten payloads, .410 duck loads can kill cleanly—but they require discipline, patterning, and hard range limits.

How Far Can You Shoot Waterfowl Ethically?

Ethical range is determined by pellet energy and pattern density—not ego. Steel waterfowl ammo is generally effective to 30–40 yards. Tungsten extends that window to 50–60 yards in capable hands. If you wouldn’t shoot that bird on the ground at a given distance, don’t shoot it in the air.

Tony Vandemore’s Waterfowl Loadout and Why It Works

Vandemore relies on high-density tungsten to shoot smaller pellets while maintaining lethal energy.

“When it comes to picking the right load for waterfowl, it all comes down to density for me,” he says. “I shoot sub-gauges religiously and have always favored tight chokes like Rob Roberts Custom Gunworks R3 and smaller, higher density pellets that provide a very dense pattern.”

Vandemore explains that 12-gram density HEVI-XII lets him shoot two sizes smaller pellets than steel with increased lethality downrange. With smaller pellets, there are a lot more of them, which equates to much better pattern density. Birds can’t fly through a pattern like that.

“My preference is HEVI-XII 3-inch 6 in 28 gauge or 20 gauge for ducks and Canada geese,” he says. “I'll occasionally drop down to 4s for Canadas late season. I encourage you to pattern your gun before season and get a feel for which choke constriction and shell it patterns best with. I know how the HEVI-XII 6s perform out of my guns and the incredible patterns they provide. So, I shoot the same choke and load pretty much throughout the entire season, from early teal season to late-season Canadas.”

Load: HEVI-XII 3-inch #6

Gauges: 20 gauge and 28 gauge

Choke: Rob Roberts R3

Rationale: More pellets, more hits, and consistent performance from teal season through late honkers.

What Makes HEVI-XII Different?

HEVI-XII is true tungsten waterfowl ammo at 12 g/cc density. It retains energy, allows smaller shot sizes, and when shooters opt for smaller shot, it dramatically increases pattern density compared to steel.

How to Pattern Your Shotgun for Waterfowl Season

Patterning is non-negotiable. Test at 30, 40, and 50 yards. Count pellet hits within a 30-inch circle. Change chokes to dial in the one that gives you results that kill at the distances you expect to shoot. Find the combination that prints even, lethal patterns.

Common Mistakes When Choosing Waterfowl Ammo

There are some pitfalls, so it’s up to you to avoid them. They include running oversized shot with tungsten, failing to pattern when choosing loads and chokes, ignoring how wind factors into your hunt, and choosing shells based on habit instead of performance.
