Is slapping down unconstitutional laws that haven't been around very long really "expanding" 2a rights? It's not like these rulings are allowing me to mail order machine guns like people use to. If by expanding the mean restore rights, sure.
The rulings just allow people to continue to own things in common use or do things that are legal in a vast majority of states. Keep in mind some of the laws in California involve things like demanding firearms have tech in them that doesn't exist.
