Holy cow! I have to tell you guys about one helluva gun safe.
My Grandpa had a friend that did earth moving for a living. He dug a hole, poured a concrete floor, somehow got ahold of a BANK VAULT, pushed the vault on to the floor, poured some walls for a foundation & set a trailer house on top. That vault was his gun safe! You could fit 4 people in it easily & it was lined w/ racks & shelves. I remember him showing me his 257 Roberts & other rifles. He had gobs of guns! That vault is still in the basement under that house. The only way that vault will disapppear is if the house disappears.
