If it is all original parts it sounds like its pushing the antique mark, I would have put it on my wall before i put any rounds through it. Older barrels don't handle new loads too well. Damascas barrels anyway, they can't handle the pressures of new propellents very well. I think you should have a gunsmith look at it and if you want to go the way of cleaning the bore, let him do it, it might only require a clean with bore cleaner (pretty much acid).

yep yep!

Got it clean as with my bronze .308 brush with cloth and wd40 in a drill!
happy, yeah i had actually thought of the whole 2.5 2.75 thing and it seems that my 2.75s fit in it fine, I'll take it to be looked at tomorrow though eh, its got matching serials and everything on all the parts, so yeah.
either way it's going to need completely rebluing and i will redo the woods.

Remember, shotgun chambers are measure with the crimp OPEN. A 2 3/4" cartridge is closer to 2 1/2" loaded and extends the extra 1/4" upon firing. Even though a standard length round will fit, the question is will it fit when fired?
Try dropping a fired hull with the crimp extended as much as possible. If that will drop in smoothly you "may" have a standard length chamber. If the barrel is not marked with a chamber length, you really should have it checked by a competent gunsmith. He/she can also give you a good idea of the overall safety level of the gun with modern ammo.
In life, strive to take the high road....It offers a better field of fire.
