over the years, many thousands of pre ww2 double guns were made with chambers less than 2 3/4", which is the standard length for most shotgun shells these days...
have noticed that if gun with lengthen chambers is of english make, then some here make a big deal about it...
why is that? so long as there is sufficent metal left in front of the chambers for safe shooting, what difference does it make?

If you don't like it, there are pens that can touch 'em up? Just kidding Ed, if 2 3/4" is good, three is better? Is it worth closing the sale by saying, and you can get shells for it at wallymart?

Ed, if you haven’t noticed yet, originality is prized among collectors of vintage guns. None more so than American collectors of American makes. Lengthening the chambers is messing with originality, regardless of being safe or not. It’s not any more complicated than that and the quest for originality covers all aspects of the gun, not just the chambers.

Why lengthen the chambers if you can shoot 2 3/4" low pressure shells out of a 2 1/2" chamber? Per these two threads and Sherman Bell's articles, there is not that much pressure increase. https://www.doublegunshop.com/forums/ubbthreads.php?ubb=showflat&Number=34376http://www.16ga.com/forum/viewtopic.php?t=1983On the other hand, an acquaintance who was close to the late Cyril Adams had this happen to him after he lengthened chambers from 2 1/2" to 2 3/4". He had this to say: "I bought the gun for me as it is a non rebounder. I did not have it proofed because I never intended to sell it. When it arrived I observed that the chambers were very thin compared to most. I recut the chambers to 2 3/4. I only shot light 28g shells through it and it performed flawlessly for over 500 rounds. I was preparing for the Adam’s cup and could only find 1145fps 32g loads. It let loose after the 15th one."

I just lengthened a GECO Belgium gun to 2.75, I also opened the chokes to Skeet/IC It is my gun, for me to shoot, and if I hurt the value, that is OK to me, The chambers are stout.
I do load 2.5 inch 16 gauge ammo, for my old Kreighoff drilling and my Win Model 12s but I have flats upon flats of 2 3/4 ammo. I am happy
Mike

I like the subsequent purchaser argument put forth previously. I once owned a hammer gun proved as a 12 with 2 3/4 chambers and then successively enlarged to 10 bore with 2 7/8 chambers, presumably by various generations of American gunsmiths. The guy I bought it from was insistent it was a 10 and did not believe it had started life as a 12. When I sold it, it was only with full disclosure of the modifications.

Most French guns have stout chambers and muzzle wall thickness. While you should always measure (Gene’s anecdote about a guy who KNEW the chambers were thin, and lengthened them anyway, demonstrates that not everyone who has gun smith tools should be allowed to use them) it has been a long time since I measured a French gun with less than .050 wall thickness, and a bunch of metal in the chamber/forcing cone area. If you find that, you could certainly consider lengthening the cones, or, the chambers, or both. I’ve done it, told people to do it, and, sometimes just not done it, even though I think I could. Depends on the gun and the use it is going to get. I have a single, French, 2 1/2” 12 that I am using as is, mostly because there is a flat or so of 2 1/2” stuff on the shelf, and I intend to chase pheasants in the cold with it. That, and I’m cheap, and hope that 2 1/2” ammunition returns before I’m dead.
Might not, though. We will see.
Best, Ted

Too easy to find proper loads on the internet or roll them yourself. And as we have covered many times it is not how long but how high pressure they are that is important. A 600Jr and a hundred dollars of stuff will make a lot of proper loads for shorter chambered guns. So why ream them out and hope they still have enough metal to shoot too high pressure loads?

"When I sold it, it was only with full disclosure of the modifications.'
I'm sure Ed is really at heart a fine man. He has a melodious voice and can sell stuff. Sorry though, I don't believe that statement.
On the other hand, when we were in the middle of the Covid supply issue crisis I bought a flat of old 2 3/4" low pressure Federal shells. I intended to use them in my French 1926 SxS...lots of barrel thickness, choked at .024, .024. I was tempted to try them in the Damascus Reilly but decided to wait. The issue is still not resolved in my mind and I've read the DBS lines and others. I'd still prefer to shoot 2 3/4" low pressure shells out of a 2 1/2" chambered gun than rechambering it.

Agreed, completely. And, it underscores the obvious ............. Ed cannot help but rehash old subjects that he is too lazy to do a search for.
May God bless America and those who defend her.
