By the way, that's a pretty good price they are offering.  If it were me, I would buy a couple hundred rounds and give it a test drive.  Heck, if you are planning to pick up an old Nagant, I would go ahead and buy some ammo now.  You won't have any trouble finding the rifle, there are tons of them floating around out there.  I bought mine for $50 at a gun show a few years ago.
