Steel Shot vs Bismuth: Ammo Choices for Waterfowl Shotguns

When it comes to waterfowl hunting, the choice of ammunition plays a critical role in both your hunting success and the environment. Two popular options for shotgun loads are steel shot and bismuth shot. Each has its unique qualities that make it suitable for different hunting conditions, target species, and regulatory requirements. Understanding the differences between steel and bismuth shot can help you make an informed decision about which is best for your hunting style, and in some cases, the location where you hunt.

In this article, we’ll compare steel shot and bismuth shot, covering their performance, cost, environmental impact, and how each fares in different hunting scenarios.

What is Steel Shot?

Duck hunting often requires the use of steel shot, one of the most commonly used types of ammunition for waterfowl hunting. It has been the standard since lead shot was banned in the early 1990s due to its toxicity to wildlife. Steel shot is made from, as the name suggests, steel, a relatively hard and dense metal. This density plays a key role in how steel shot behaves when fired and how it affects the target.

Advantages of Steel Shot

Affordability

One of the most significant advantages of steel shot is its affordability. Steel is a relatively inexpensive material, and as a result, steel shot is generally much cheaper than alternative options, such as bismuth. This makes steel shot a more cost-effective choice for hunters, especially for those who go on frequent hunts or use large quantities of ammo.

Availability

Steel shot is widely available in stores and online. Because it is the most common alternative to lead shot, most ammo manufacturers offer a variety of steel shot options, with different load sizes, pellets, and shot weights. The effectiveness and performance of steel loads are particularly notable for waterfowl hunting, especially for ducks and geese. This makes it easy to find steel shot ammo for different types of shotguns and hunting situations. Additionally, there is a wide range of shot sizes available in steel shot, allowing hunters to choose the best option for their specific needs and ensuring optimal performance in the field.

Environmental Impact

Steel shot is less harmful to the environment than lead. Lead shot can poison wildlife that ingest it, such as waterfowl, and it can also poison other animals that feed on carcasses or residue. Steel shot, on the other hand, does not pose this same threat, making it the environmentally friendly choice when hunting waterfowl.

Disadvantages of Steel Shot

Lower Density

One of the main drawbacks of steel shot is its lower density compared to lead or bismuth. Steel is not as dense as other materials, which means that steel shot pellets are less effective at carrying energy over longer distances. This results in a lower killing power at range, requiring hunters to use more pellets to achieve a clean shot. In contrast, high density shot materials like bismuth or tungsten provide greater penetration and accuracy at longer ranges due to their increased mass, which helps mitigate issues like wind drift and allows for higher pellet counts in patterns.

Reduced Pattern Density

Because steel pellets are smaller and lighter than lead or bismuth pellets, they don’t maintain their shape as well when fired, which can reduce pattern density. This means that steel shot may have a less effective spread than heavier shot materials, which could affect the consistency and coverage of your shots.

Potential Barrel Damage

Steel shot is harder than lead, and using it in older shotguns or in those not designed for steel shot can cause barrel damage over time. Most modern shotguns are designed to handle steel shot, but it's always wise to check with your firearm manufacturer to ensure that your gun can safely handle this type of ammunition.

What is Bismuth Shot?

Bismuth shot is an alternative to steel that is made from bismuth, a heavy metal with a density closer to lead than steel. Bismuth shot was developed as a non-toxic alternative to lead shot, and it provides hunters with a similar performance to lead while still being safe for the environment.

Advantages of Bismuth Shot

Higher Density

Bismuth shot has a higher density than steel, which translates to more energy delivered to the target. This higher density gives bismuth shot greater downrange power, making it more effective for longer shots. The added density means that bismuth shot pellets are also larger than steel pellets, increasing their impact and ability to kill more cleanly. Additionally, selecting the appropriate shot size is crucial as it affects pellet count and the density of the shot pattern, ultimately influencing hunting success.

Similar Performance to Lead

One of the key benefits of bismuth shot is that it mimics the performance of lead shot more closely than steel. The added density means that bismuth performs better than steel in terms of energy transfer, shot pattern density, and penetration. For hunters who prefer the feel and results of lead shot, bismuth is a great option.

Less Damage to Barrels

Unlike steel shot, bismuth is softer and less likely to cause barrel damage over time. This makes bismuth a good choice for vintage shotguns or those with more delicate barrels. Additionally, bismuth shot tends to be gentler on chokes, allowing hunters to use tighter chokes without worrying about damage.

Disadvantages of Bismuth Shot

Higher Cost

The primary disadvantage of bismuth shot is its cost. Because bismuth is rarer and more expensive to produce than steel, bismuth shot is generally much more expensive. This higher cost can be prohibitive for hunters who need to stock up on ammo for the season or for those who hunt frequently.

Availability

While bismuth shot is becoming more common, it is still not as widely available as steel shot. Fewer manufacturers offer bismuth ammo, and it can sometimes be harder to find in local stores. This limited availability can make it challenging for hunters to find the specific loads they need.

Heavier Than Steel

While bismuth’s higher density offers more energy, it also means that bismuth shot is heavier than steel. This can affect the number of pellets in a shell, meaning that bismuth loads often contain fewer pellets than their steel counterparts. While the pellets are more powerful, hunters may need to account for the reduced pellet count and variations in shot sizes in their shot selection.

Steel Shot vs Bismuth: Which One to Choose for Waterfowl Hunting?

The choice between steel and bismuth shot depends on your individual needs, preferences, and the type of hunting you’re doing. Choosing the right ammunition is crucial for hunting ducks, as factors like shot size, velocity, and range can significantly impact performance in different environments. The type of ammunition you select can also affect your ability to kill ducks effectively, making it essential to consider both the technical aspects and your personal experiences when making a decision.

Choose Steel Shot If:

• You are hunting in areas where cost is a major factor, and you need to stock up on a lot of ammo.

• You need a widely available and affordable option for frequent hunts. Specific steel load options, such as Federal Speed-Shok and Remington Nitro-Steel, are cost-effective choices that offer reliable performance.

• You’re hunting in regions where environmental regulations require non-toxic shot, and your main concern is affordability.

Choose Bismuth Shot If:

• You prefer the performance characteristics of lead shot, particularly in terms of range, pattern density, and overall energy.

• You’re hunting in areas where precision and longer-range shooting are essential. Bismuth shot is particularly beneficial for a waterfowl hunt requiring precision and longer-range shooting.

• You’re using vintage or high-end shotguns that require softer ammunition to avoid barrel damage.

Conclusion

Both steel shot and bismuth shot offer distinct advantages depending on your hunting needs. Steel shot is a budget-friendly, environmentally safe option that is perfect for hunters looking to maximize the number of rounds they can use. However, bismuth shot delivers superior performance with higher energy and more effective penetration, making it a great choice for hunters seeking the closest thing to lead shot performance without the environmental impact. While bismuth is more expensive and less widely available, its performance makes it worth considering for serious waterfowl hunters looking for the best possible results.
