We have to know the wall thickness at various places. Your mentioned wall thicknesses at areas close to the breech are unacceptable, but more acceptable very close to the muzzles.

While only for curiosity sake, it would also be nice to know the maker of your potential "Best" gun. But the really critical stuff involves those wall thickness measurements and where they are located. UK Gun trade minimum wall thickness is .020. Purdey's won't accept anything under .022.

If that gun is not in proof you will suffer from a costly event. Take it to a qualified gunsmith to determine if it is in proof. If in proof, you have to determine if you want a gun with thin barrels.

In this case it probably doesn't matter where these measurements are. That is very thin regardless of where the measurement is. And remember, the smaller the gauge gets, the higher the pressure goes.
Granted 16 gauge pressures are not too far off from a 12, but if the bare minimum for a 12 ga. is .020, that should tell you something. If this is a best gun (and everything that implies financially), it could not be submitted for proof with those measurements. If the sleeving is done here in the US, and not re-proofed, it does significantly hurt it's re-sale value down the road. May or may not be a consideration right now, but is something to think about before a price is agreed upon.

Take a look at a .018 or .020 feeler gauge . I did. I don't think I would be comfortable with it.

Forrest: The Birmingham Proof House does not reject barrels for proving based on wall thickness, and if that .018" is out toward the muzzle, it could well pass.
http://www.gunproof.com/Proofing/proofing.html The barrels are at much higher risk of a dent. While we're here, some factory small gauge Parkers have been documented to have MWT in the distal barrels less than .020". http://parkerguns.org/pages/faq/BarrelThickness.htm

In simplest terms the current owner of this gun is trying to make his problem your problem.

That depends on how you define "problem." And the price of the gun.
Let's see... A well-priced Purdey with barrels .018 out at the muzzles? Or a mainstream Parker VH with plenty of thickness throughout? Personally, I'd take the Purdey in a heartbeat. Then be careful about dents. But this is all banter. "Gunner" must make the choice. |
