"seven of the eight bolts"??? There should be only four scope base screw holes in that receiver. Are you counting the screws in the scope rings or did someone drill four more holes in the receiver? BTW, the scope ring screws and the base screws are not the same. Ring screws usually are 6x40 where base screws are 6x48.
Well, I was using Natural Light as the cutting lube....
Four base screws is the correct number.
