Quick Answer
Bismuth tungsten loads may offer a viable alternative to steel for waterfowl hunting, as they produce denser patterns and less lead exposure, but their performance depends on factors such as shot size and choke.
Ballistic Performance
Bismuth tungsten loads typically use larger shot sizes, such as 3.5-4.5mm, which provide better penetration and more effective patterning at longer ranges. A well-placed 3.5mm bismuth tungsten load can achieve a similar effect to a 2.5mm steel load, but with fewer pellets. For optimal performance, use a choke that tightly constrains the shot pattern, such as a full or extra-full choke.
Field Performance
In field tests, bismuth tungsten loads have consistently demonstrated their ability to take down waterfowl humanely, often with minimal damage to surrounding flesh. When used in conjunction with a shotgun choke, bismuth tungsten loads can achieve effective killing ranges of up to 40 yards. To ensure success, it is essential to use the correct shot size and choke combination for the specific waterfowl species being hunted.
Safety and Regulations
Bismuth tungsten loads offer a safer alternative to steel for waterfowl hunting, as they contain less toxic material and produce fewer lead residue fragments. However, check local and national regulations before using bismuth tungsten loads, as their use may be restricted or prohibited in certain areas. Hunters should also be aware that some shotguns may require special maintenance or cleaning to accommodate the use of bismuth tungsten loads.
