How to Clean a Shotgun
Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.
Clean your shotgun by removing the barrel, running solvent-soaked patches through the bore, scrubbing with a bore brush, then wiping down all metal surfaces with gun oil to prevent corrosion.
How This Affects Longevity
Regular cleaning prevents corrosion that can ruin your barrel and action, especially after shooting corrosive ammunition or in harsh conditions. A clean shotgun cycles more reliably and maintains accuracy over thousands of rounds. Most feeding and ejection problems stem from accumulated fouling in the action.
The Detail
Start by ensuring the shotgun is completely unloaded and pointed in a safe direction. Remove the barrel according to your specific action type, whether that's unscrewing the magazine cap on a pump gun or operating the release mechanism on a semi-auto. This gives you clear access to clean from the chamber end, which prevents pushing fouling deeper into the barrel.
Run a bronze brush soaked in bore solvent through the barrel multiple times to break up powder residue and plastic fouling from shot cups. Follow with clean patches until they come out white, then finish with a lightly oiled patch. Pay special attention to the forcing cone area where the chamber transitions to the bore, as this sees the highest pressures and fouling buildup.
Clean the action by removing visible fouling with a brush and solvent, focusing on the bolt face, extractor, and ejector mechanisms. Wipe down all metal surfaces with a light coat of gun oil, but avoid over-lubricating as excess oil attracts dirt and debris. The trigger group typically needs minimal cleaning unless you've been shooting in extremely dirty conditions.
Reassemble carefully and function-check the action to ensure everything operates smoothly. Store the shotgun in a dry location with a light protective coating on all metal surfaces.
Build Impact
Proper cleaning habits extend your shotgun's service life significantly and prevent costly repairs from neglect. A well-maintained shotgun holds its value better and performs more reliably when you need it most.
