What is the scope of a search warrant that authorizes a warrant to search a home for illegal weapons?

A lawful search of fixed premises generally extends to the entire area in which the object of the search may be found and is not limited by the possibility that separate acts of entry or opening may be required to complete the search. Thus, a warrant that authorizes an officer to search a home for illegal weapons also provides authority to open closets, chests, drawers, and containers in which the weapon might be found ... This rule applies equally to all containers. (United States v. Ross, supra, at 820-821, 102 S.Ct. at 2170-2171)
