I have always cussed at threads on gun forums for costing me money, but this one may definitely take the cake. I've also been looking at adding an additional safe because mine is overflowing. But after reading and watching videos, I'm strongly considering building a walk in safe addition onto my house. Concrete walls, floor and ceiling with a vault door entrance from inside my house. A contractor friend of mine recommended building it out of fox block and adding a Sportsman Steel vault door.
