Friday Night Discussion – Quick How-To: Checking & Preserving Old Shotguns

This is my method. I don’t believe in refinishing firearms. No reblue, no stock stripping, no “making it new.” I clean them, restore function, and keep them original. Honest wear tells the story.

Function check: Cycle the action. It should move smoothly with no grinding. Test the safety. On = no trigger release, off = clean break. Check trigger reset by cycling the action after a dry fire. It should reset positively. Lightly bump the butt on carpet to confirm the hammer/sear doesn’t slip. Test extractor and ejector with a snap cap or dummy round. The extractor should grab the rim and the ejector should clear the round if equipped. Close the action and check lockup. A little play can be normal on older designs, excessive movement is not. Dry fire and look at the breech face. The firing pin should protrude briefly and retract. Inspect the barrel with a light. Look for dents, bulges, ring shadows, or heavy pitting. Any serious defect or excessive play = gunsmith.

Homemade snap cap: Take a fired hull and deprime it. Fill the primer pocket with hot glue or RTV silicone. Let it cure fully and trim flush. This cushions the firing pin safely. Short-term options are a trimmed pencil eraser or a cut-down plastic wall anchor pressed into the primer pocket. Never use live primers, metal, or epoxy.

Cleaning only, no refinishing. Metal: Apply CLP or penetrating oil. Use bronze wool to remove surface rust. Wipe clean and leave a light oil film. Preserve the patina. Wood: Wipe with a barely damp cloth and mild soap if needed. Dry immediately. Feed the stock with a very light coat of boiled linseed or tung oil, then wipe off excess. No sanding. No stripping. No polyurethane.

Removing stock dents with steam: Place a wet cloth over the dent. Apply a hot household iron. Steam swells compressed fibers. Repeat until level. Don’t overheat or soak the wood. Let dry 24 hours before oiling.

Smoothing a rough slide or action: Field strip and take photos. Clean rails and channels with solvent, Q-tips, and a toothbrush. Most rough actions are dried grease and dirt. Polish only contact areas using 600–1000 grit wet/dry paper on a wooden dowel. Follow factory direction with light pressure. Areas to polish: action bars, bolt carrier sides, receiver rails. Do NOT touch locking lugs or sear surfaces. Finish with a mild metal polish on a cloth. Reassemble with light grease on rails and oil on pivots. Cycle the action 50–100 times. No power tools. No Dremel.

Chamber reminder: Many older shotguns are fixed choke and have 2½” chambers. Measure before firing. Don’t assume 2¾” is safe. Wrong shell length raises pressure.

Bottom line: Clean it. Restore function. Keep it original. Preserve the history.
