Can You Use Tungsten for Non-Toxic Waterfowl Hunting?

History of Non-Toxic Hunting

The use of non-toxic shotshells for waterfowl hunting began in the 1970s, when the US Fish and Wildlife Service banned the use of lead shot. Bismuth-tungsten loads were developed as a safer alternative, with bismuth acting as a matrix to hold tungsten particles in place. This combination provides a dense, non-toxic shot that’s effective for hunting waterfowl.

Bismuth-Tungsten Load Characteristics

Bismuth-tungsten loads typically consist of a mixture of 80-90% tungsten and 10-20% bismuth. The tungsten particles are usually in the form of very fine, spherical pellets that spread out upon impact, causing maximum damage to the target. Bismuth-tungsten loads are often used in 12-gauge shotguns, with 3-inch shells being a popular choice for waterfowl hunting. When selecting a bismuth-tungsten load, it’s essential to choose a shell with the right balance of tungsten and bismuth to ensure optimal performance.

Field Testing and Performance

Numerous field tests have demonstrated the effectiveness of bismuth-tungsten loads for waterfowl hunting. In one study, bismuth-tungsten loads were found to deliver 90% or more of the shot within a 30-inch circle at 40 yards, making them ideal for hunting ducks and geese. When used in conjunction with a well-placed shot and proper hunting technique, bismuth-tungsten loads can provide a high success rate for waterfowl hunters.
