Saw a friend Cut in some double gang or maybe triple gang Remodel J boxes through out the House. Can probably get 5?k if they are large bills into one J box. Install solid Cover plates.

Or just few single J boxes with a plug.
Just hope the thief doesn’t need to plug something in. So keep that plug away from your safe

All of them do something better than the 30-06, but none of them do everything as well.
