I have a couple of friends that have Safe Rooms in their homes. One is a FFL, his room was the first thing build when he built his house, everything else was built around it. In all cases, the cinder blocks are highly reinforced with large rebar running through it and cross welded at various points along the vertical. The ceiling also are cement with a lot of rebar to reinforce the structure. A simple jack hammer won't help much unless you add a torch to cut the rebar as you encounter it. They wouldn't tell me much more than that other than to say, the design is more of a bank vault than a cement wall room.
I agree with the other members. You shouldn't provide too much information here on line. It would be easy enough for thugs to find this thread or any other media you discuss this on. I have seen my wife look up people on line and in about 30 minutes know more about them than anyone would care to imagine.
Your project is one that I would also like to put into my next home. For many reasons. Although I doubt that it will be in my budget. But you never know!
