DHE barrels

I would like to know more about chamber sleeves, if there is such a thing.

When done it is basically soldering in sleeves to the chambers to reduce the gauge down to a smaller gauge. It is similar to the installation of gaugemates or briley tubes, just without the tube in the bore.
I personally would never do it to a gun, it does not make much sense to me and I would think the performance would be hindered some. Tubing the gun with brileys would be a better solution in my book.

The only time I ever heard it done that made any sense was a 14ga had it's chambers sleeved to 16ga.

Jeff, I remember your post where you said Turnbull indicated the chamber wall was thin, I don't recall whether it was them that said something about chamber sleeves, but what was their thought process? Sleeving the chambers to .410? That would be ill thought out, as the .410 charge, wad and shot, would never fill the 28ga bores to build any sort of adequate pressure. it woudn't be of any use beyond 15-20 yards. Sleeving them with same bore sleeves wouldn't yield any increase in the wall section either.
Unless someone lengthened the chambers to 2/75" or 3", I can't see how the chamber wall was any less than when the gun was made.

I don't think we have heard the entire story.

Bill I was hair on fire when they told me walls were thin and the guy at Turnbull him hawd on if i could still shoot her. Since I’ve calmed down after talking to several people giving them the wall thickness numbers I was told. It’s a 00 28 inch barrel 28 gauge my great grandfather bought in 1917 that was treated like a field hand by my great uncle who got it after my great grandfather died. I traded a set on horns that came off the first steer butchered at the Swift Ft Worth plant to my second cousin for her. I then sent her to Turnbull for a full restoration. Got her back a few days ago. New stock, forearm, dent taken out of barrel, re blued, re case hardened, internals fixed and some parts replaced. Looks like she did when my great grandfather ordered her from H&D Folsom arms co In 1917. Im her caretaker for the next 20 to 30 years then I will hand her off to my favorite nephew. I just would like to get the repro barrel on her now so I can just shoot the hell out of it at clays and or daily hunting, and put on original barrel for a dove shoot and a quail hunt a few times a year.

Why can't you "shoot the hell out of it" with the original barrels? Give us the real wall thickness in the vulnerable parts of the barrels, and we will tell you if it is reasonable.

Well I shoot every day, I don’t seem to get much better, but I live on a cow ranch so the clay machines are almost at my back door. Normally I shoot75 to 100 daily. The wall thickness I got back from Turnbull says .027 last 12 inches of barrels.

If it were me, I'd sell the repro barrels and save myself the expense of modifying them. Then take what you saved, and what you got for the barrels, and go out and buy another gun, repro or not, and shoot it like you would have if you'd fitted them to your grandfather's gun. Life is too short to sit and wait for another job to be completed.

Why I messaged you. I think I remember reading over here somewhere that a lot of sub gage guns were made thinner than modern guns. I shot her yesterday with a recipe I found with only 5000 psi. She did crush some clays. The chamber sleeve was just something I saw Briley did and was curious what it was since the man at Turnbull said the chamber walls were too thin to lengthen to 2 3/4. When I sent the gun off I thought I needed the longer chambers, since then I’ve come to the conclusion I don’t, since most low pressure loads I find for 2 3/4 you end up stacking Cheerios and other fillers in to take up space but fit perfectly in 2 1/2.
Btw thank you again for your advice from when I messaged you.
