All of this is interesting and isnt education a wonderful thing. There's a lot of math and physics lessons here. And this leads me to believe ever more firmly as to my stated opinion in post #55 of this thread,namely, that if someone broke into your home without the knowledge of you owning the Sturdy,the Liberty Presidential,my BF 66X36,there is a very good possibility that once the perp(s) came across your safe that was bolted down and placed correctly in a corner or recessed alcove such as a tight closet, and unless you had some heavy duty tools lying about it is very unlikely that they will be getting into one of these safes with what they used to pry their way into your humble domain. Which should be something that everyone who is contemplating buying a thin 12 gauge gunsafe with a flimsy composite door should rethink,save some more money,and buy something more on the lines of the Sturdy or BF or something as well made or even better. This has been a lot of fun guys.
