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.

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.
