Tungsten for Waterfowl: Does It Offer Better Penetration?

Understanding Tungsten Alloys

Bismuth-tungsten loads utilize a tungsten alloy, typically made from 90% tungsten and 10% bismuth. This unique alloy provides a denser, harder core that maintains its integrity upon impact, resulting in deeper penetration and wider expansion. The bismuth content also helps to reduce the risk of over-penetration and minimize lead contamination.

Reloading and Optimal Performance

To ensure optimal performance from bismuth-tungsten loads, it is essential to follow specific reloading guidelines. When loading 12-gauge shells, a 3-inch shell with a 1-1/8 oz. bismuth-tungsten payload and a 1-inch velocity is ideal for waterfowl hunting. This setup provides a balance between penetration and knockdown power, making it effective for hunting geese and ducks.

Field Results and Considerations

In the field, bismuth-tungsten loads have shown to penetrate up to 20% deeper than traditional lead loads, resulting in increased effectiveness against waterfowl. However, it is crucial to note that these loads can be more expensive and may require special handling and storage. Hunters should also be aware of local regulations regarding the use of non-toxic loads, as these restrictions vary by region and country.
