What's the best way to clean a shotgun after using slugs?

Removing Debris and Spent Shell

When cleaning a shotgun after using slugs, it’s essential to remove the spent shell first. Hold the shotgun with the muzzle pointing downwards and gently pull the shell out of the chamber. This will prevent any remaining debris from falling back into the chamber. For added safety, inspect the chamber and barrel for any remaining debris before proceeding.

Cleaning the Action and Barrel

Break down the action by removing the bolt or slide, depending on the type of shotgun you’re using. Use a soft-bristled brush to gently sweep away any debris that may be stuck to the bolt, slide, or other internal components. Next, use a patch or cleaning cloth to apply a small amount of bore solvent to the barrel. Run a cleaning rod through the barrel to work the solvent deep into the rifling. Use a series of clean patches to remove any remaining debris and solvent residue.

Final Inspection and Storage

Once you’ve cleaned the action and barrel, inspect the shotgun to ensure it’s free of any remaining debris or solvent residue. Apply a thin layer of gun oil to the moving parts and chamber to prevent corrosion. Store the shotgun in a dry, secure location, with the action closed and the muzzle pointed downwards. This will help prevent any debris or moisture from accumulating in the chamber or barrel.
