That's a beautiful rifle - congratulations!

I'm curious - are they blued damascus or steel barrels?

Have you looked inside the locks to determine who made them?

Cheers!

I've not yet looked inside the locks. I believe the barrels are steel and not damascus, based on what I'm seeing, particularly under the forearm.

That is a very nice double rifle in what appears to be very nice original condition. Sad that the worms also found it to be so attractive. I'd agree that the horn buttplate should be replaced rather than wasting time and money on a repair.

There is a guy here named Joe Dobrzynski who often sells Buffalo Horn material for buttplates, grip caps, etc. I think he also sells horn material on Ebay. Here's a link to one of his recent For Sale ads here:

This gun is in original condition. Wow. Great find.
Olde Eynsford powder works best out of all powders in my BPE rifles. I have tried Goex, Elephant, Swiss (not too bad), and Olde Eynsford. OE is much better, more powerful than the others in my brass case cartridges. This gun no doubt needs paper patched bullets.

Thank you all again for the help. So now I've slugged the bore, driving a Hornady 50cal muzzleloading conical projectile 3 inches into the right bore, starting at the breech end. After popping it back out, I'm seeing what started as .505-.506 now is .496 where the lands impressed/indented the lead. I think these measurements are accurate. Isn't that too small?

The rifles proofs show a 39 bore.

Couple of thoughts: proof versus service load are two different things. So proof marks are often just indications, not gospel or science. Second, you should slug both barrels at each end. That is, drive a slightly oversize slug through each chamber and out an inch or two. Then run a slug all the way down each bore. You will probably find that the bores are tapered. About 2-4 thousandths. Tapered bore was almost standard in British BPEs. So see how your big bullet is starting out versus what it is exiting as.

The old .500 bullets ran around .502 bare. Wrap 'em in paper and shoot 'em - you'll be fine.
