Well, I called the seller, (a very reputable gun store), and he told me that Ruger does indeed do a very poor job of cleaning the guns when they test fire them. Based upon what I'm seeing in terms of grime, a cylinder or less has been fired, so this more or less confirms my suspicions.
UPDATE: No. 13 and Bore Butter took all the factory crapola out of the bore. Got a mirror shine in there. Dunno if it was fouling or storing grease or what, but its gone now.
