Just to clarify, Paul's ".100 to .120 around the breech end" would refer to the end of chamber wall thickness.
I just measured the at the very end of the breech WT of a 10g Ithaca at .230", a 12g 00 Smith at .210", and a 16g 0 Regular frame Smith at .200".

I saw the chart and downloaded it. I was only worrying about pressure. People go wild when I mention a Damascus barrel.

Kevin: before using the gun with any load, the wall thickness needs to be measured from breech to muzzle. Please share the numbers with us after having it measured.

I already shot it. Works good. There is a bit of rust in the barrels but nothing crazy. I dont even know how to measure the chamber thickness? I can put calippers at the end of the muzzle to measure the thickness but no idea how to get the chamber thickness.

You can get close by using a scale to measure the thickness of the wall where the shell goes in. Measuring the thickness of the walls from breech to muzzles is the ideal thing to do, but sorry to say, I've never done that and have owned over 25 or 30 different Damascus barreled guns. Four or five friends at the club have also owned many Damascus guns and no one has ever measured barrel thickness. I don't measure chamber length either. As for "published data " for the 10ga, Hodgdons has just put out one 10ga low pressure load and then there's Petes' data. That's about it. Low pressure loads to me are more about common sense than anything else. If it'll work in a 12, it'll work in a 10, with lower pressure. I'm not a collage grad, but I think it has to do with the volume the pressure has to work against. The bigger the volume, the less pressure. JMHO

Paul, I'm not picking on you but I don't think that's good advice for somebody just getting into old shotguns, especially classic old side-by-sides. There are enough of them out there that have been honed nearly to death and the chambers lengthened to dangerous wall thicknesses that are literally "time bombs" and shouldn't be shot with ANY shell. Although I have done the same as you, I would never advocate an attitude of 'just go ahead and shoot it - it will probably be fine' - rather I would give the strong advice to have the wall thickness measured by somebody who knows how to do it...... especially in this case where the poster says "There is a bit of rust in the barrels but nothing crazy." where we have no idea of his definition of "nothing crazy". .

Manson wall thickness gauge, $160.99, retail, don't know the dealer price. I paid about $100.00 for mine maybe ten years ago. That $160.99 item will probably sell for a bit more at the estate sale. Mine has already appreciated 61%.

Dean, I get picked on so much over in the shotgun room at the club a little here won't make any difference. Maybe I should have put a disclaimer in my post. You're right, it would be nice to measure the wall thickness. I'm use to looking at American made SxSs, which are a bit thicker than our English cousins. Over there the guns were usually gone through at the end of hunting season, and that could mean a honing of the barrels. Back here the gun was usually just oiled up and put in the closet, no honing. I'm use to looking at muzzles with .040 to .060 wall thickness. With that in mind I assume, right or wrong, the rest of the barrels are still factory specs. I believe over there .020 at the muzzle and they'll still proof load and test it. I wouldn't shoot a gun with .020 at the muzzle with your fingers. No offense taken by your post - I think we're on the same page.
