Can Bismuth Loads Be Used in Pump-Action Shotguns?

April 5, 2026

Quick Answer

Yes, bismuth loads can be used in pump-action shotguns, but it's essential to follow specific guidelines, as excessive wear on the shotgun's components may occur due to the bismuth's abrasive properties.

Pump-Action Shotgun Considerations

When using bismuth loads in pump-action shotguns, it’s crucial to be aware of the potential risks involved. Bismuth is a softer metal than lead, which can lead to increased wear on the shotgun’s components over time, particularly the chamber, barrel, and action. This is because bismuth is more prone to scratching and scoring, which can cause the shotgun to become less reliable and potentially lead to misfires.

Choosing the Right Bismuth Load

To minimize the risks associated with using bismuth loads in pump-action shotguns, it’s essential to choose the right type of load. Look for loads that have a lower bismuth content (such as 25-30% bismuth) and are designed specifically for shotguns. These loads are often formulated with tungsten or other materials that help to reduce the abrasive properties of the bismuth. When selecting a bismuth load, also consider the gauge of your shotgun and the type of hunting or shooting you will be doing. For example, a 12-gauge shotgun may require a different type of load than a 20-gauge shotgun.

Proper Care and Maintenance

To ensure the longevity of your pump-action shotgun when using bismuth loads, it’s essential to follow proper care and maintenance procedures. Regularly clean your shotgun after each use, paying particular attention to the chamber and barrel. Use a soft cloth and a mild cleaning solution to avoid scratching the shotgun’s components. Additionally, consider applying a protective coating to the shotgun’s components to help reduce wear and tear. By following these guidelines and taking the necessary precautions, you can safely and effectively use bismuth loads in your pump-action shotgun.
