I have an external portable building as a reloading room/mancave that is insulated and climate controlled year round. I have my powder and primers stored in there which are worth gold right now. The building is lofted and I have moved most supplies up there in plastic totes. It kinda just looks like camping stuff to deter assholes if they enter. The door isnt like fort Knox by anymeans. I was looking at fabbing a toybox style lock box. Anyone know of a off the shelf lock box that I could bolt to the floor of the loft? What do you guys use if in my situation? The attched pic at the top of ladder is a loft that is 10'×4'. Box would be maybe 2x3 possibly or bigger.
