I think youd want a 10 gauge with a minimal wall thickness of .100" so when you bore it out to 8 ga youd have the .040 MWT which is what i see on alot of 8 and 10 ga doubles.
Seems like you could use one of those magnum 10 gauges and have a set of 8 ga barrels made for it of course that would set you back about 10k. I knew a gunsmith who used to bore out the H&R single shot 10 gauges to 8 ga, he proofed tested them to 21k psi. He stopped doing it though because who wants to spend $600 on reboring a barrel on what was then a $200 gun.

You’re kinda missing the point . Sure you can do all your suggesting and have a usable gun , but most people me included wouldn’t go to the trouble or expense . This is more about using something that was made in the 1880’s to early 1900’s because you already have it and load for it . And want to say you tried it for X Y and or Z .
