This video details essential shotgun servicing and maintenance procedures performed by factory gunsmiths at Longthorne Gunmakers. It covers everything from basic disassembly and visual inspection to deep cleaning of the action, ejectors, chambers, bores, and trigger plate. The importance of using quality cartridges, the oil vs. grease debate, and specific techniques for checking barrel dents are also highlighted.

Quick Summary

Regular shotgun maintenance is crucial due to high internal pressures and environmental factors. Gunsmiths recommend using quality oil over grease for internal mechanisms, as oil carries debris away. Professional techniques like using light to check for barrel dents and cleaning chokes after each use with marine grease are vital for longevity.

Frequently Asked Questions

Why is regular shotgun maintenance important?

Regular cleaning and professional servicing are essential for shotguns due to extreme internal pressures (up to 17,000 psi) and exposure to elements like salt and humidity. This prevents misfires, mechanical issues, and long-term corrosive damage, ensuring reliable operation.

What is the best lubricant for shotgun internals: oil or grease?

Gunsmiths generally prefer oil for internal mechanisms. Oil functions as a 'total loss system,' carrying away debris. Grease can trap grit and sand, creating an abrasive paste that accelerates wear on moving parts.

How can I check my shotgun barrel for dents?

A professional method involves shining a light down the length of the barrel and observing the reflection. Even minute ripples or ridges, as small as 10 microns, become visible, indicating dents or bore damage.

What maintenance is needed for shotgun chokes?

Chokes should be removed and cleaned after every use. Applying a small amount of marine-grade grease to the threads before reinstalling prevents gas and residue from seizing the choke into the barrel.
