Hay SS: Haven't heard from you in a while - hope all is well. With that Nagant you sure picked up a strange one BUT, there is a place called "Quality Cartridge" at (301 - 373-3719) and
www.qual-cart.com that might be able to provide you with brass/ammo for your Naggie. I recently read where they provided 8mm French revolver and 38/200 ammo for a fella, in addition to some other obsolete calibers.
Also, I seem to recall that you might be able to make ammo for that revolver from 32-20 brass. I guess the trick is to seat the bullets deeply enough to allow the end of the case to form a gas seal as the cylinder moves forward. You may have to play with the brass a bit to get it to the right length but I think it can be done. And I also saw an article on those revolvers (7 shot???) in either the Shotgun News (ask the gun guy) or one of the shooting magazines. I can't recall now but I think that was the gun that Rasputin, the Evil Russian Monk was shot with. I don't think it killed him, they had to beat him with a brick and drop him in the water after just to make sure.
Hope this helps. Mikey.
