From other readings I was under the impression that 6000 was the max load pressure in Damascus 10 gauge barrels. I’ve been reloading and casting for over 20 years but have never loaded shotgun shells.

Has your gun been evaluated by a competent to do so gunsmith who deemed it is safe to shoot? What is the chamber length, are you certain it is 2 7/8"? The heaviest 10ga load available at the time your gun was built was most likely 1 1/4 ounce of lead with a velocity around 1150 fps.
The spreadsheet lists all the published and tested 2 7/8" 10ga loadings I could find and their sources noted. No I do not consider all of them safe to shoot in composite barrel guns. There were 10ga double guns produced with fluid steel barrels, notably the Ithaca NID Super Ten that was designed to shoot the heaviest of 2 7/8" 10ga loadings. What a Super Ten will handle and what your gun will handle are different.
Working up the heaviest loading you can find for a near 150 year old gun is unwise and potentially dangerous IMO. A 1 1/4 ounce loading at 1150 fps out of a 10ga will take down any bird provided the choke and shot size are correct and the range is inside 40 yards. Good luck.
