Exactly what bases are the holes for? Wouldn't it be better to determine that and then round up that particular base, even if it meant a search for something obsolete? Also, one could get/make a set of blank bases with no screw holes and have holes put in them to match those on the gun. Then too it wouldn't be the first time someone filled an errant hole in a base and re-drilled a new hole to match the one on the receiver. Lots of ways to skin this cat!
One screw + epoxy might well work, but it would be a bitch to find out it doesn't when out in the woods on opening day...
