Quick Answer
After using bismuth tungsten loads in your shotgun, it's essential to properly clean the firearm to maintain its performance and longevity. This process involves several steps and requires the right cleaning equipment and techniques.
Pre-Cleaning Inspection and Disassembly
Before cleaning your shotgun, inspect it for any visible signs of lead or bismuth residue. If your shotgun has a removable choke, take it off to prevent any debris from accumulating inside the choke tube. Use a soft brush or a patch to wipe down the outside of the shotgun, removing any dirt or debris that may have accumulated.
Cleaning the Barrel and Chamber
Use a lead or bismuth-safe cleaning rod and a patch soaked in a cleaning solvent to clean the barrel. Apply gentle pressure and push the patch through the barrel, repeating the process several times until the patch comes out clean. Next, use a bronze brush to scrub the inside of the barrel, removing any stubborn bismuth residue. Make sure to clean the chamber and the area around the breech as well, paying close attention to any areas where bismuth may have accumulated.
Final Rinse and Inspection
Once you’ve cleaned the barrel and chamber, use a clean patch to wipe them down and remove any remaining debris. Inspect the shotgun to ensure that all areas are clean and free of bismuth residue. If you’re unsure about any areas, consider using a lead or bismuth-detecting solution to confirm that the shotgun is clean. Finally, apply a thin layer of gun oil to the moving parts and any areas that may be prone to rust.
