Don't have the large quantity that the OP and others may have on hand however the type and value span a wide spectrum. I really like the decoy approach and a Sam's Club safe with the Remington pumps and Glocks should satisfy a burglar as having found the cache more so than junk and this modest value is covered by an insurance rider. Your self defense and common hunting guns are fairly readily accessible and yet safe from children and house guests. The really valuable stuff is secured in such a way that it is hidden yet at the same time not in an entire walk-in room. It is much easier to fashion (and keep secret) a hidden wall or a closet than a whole room.
