The inspection is presented by experienced gunsmiths to ensure a firearm is safe and sound before purchase or further work.

Quick Summary

A basic inspection of a British side-by-side shotgun involves removing the forend and stock, examining barrels for damage, checking proof marks for chamber length, testing rib tightness, measuring bore dimensions, and assessing action tightness. Trigger pulls and ejection mechanisms should also be tested for proper function.

Frequently Asked Questions

What are the key steps in inspecting a British side-by-side shotgun?

Begin by removing the forend and stock, then inspect barrels for pits and bulging. Check proof marks for original chamber length and verify if chambers were lengthened. Tap the ribs to check for looseness, measure bore diameter and thickness, and test action tightness. Finally, assess trigger pulls and ejection functionality.

How can I check if the barrels of a shotgun have loose ribs?

A simple method to check for loose ribs on a shotgun's barrels is to gently tap them. If the ribs do not produce a clear ringing sound, it may indicate that they are loose and require attention from a gunsmith.

What do proof marks on a shotgun's barrels signify?

Proof marks on British shotguns are crucial for determining their history and specifications. They indicate the original chamber length (e.g., 'proof 1 in 8' for 2.5-inch chambers) and confirm that the firearm has passed official safety testing. If chambers have been modified, validated proof marks for the new length should be present.

How do you test the ejection mechanism on a side-by-side shotgun?

To test the ejection mechanism, ensure both ejectors function independently without causing the other to pop up prematurely. Then, test them together by pulling both triggers. The goal is to confirm they work reliably and separately, as well as in unison.
