Thread: Shipping container for gun vault/C category?

With me and the missus looking at purchasing a house very soon the idea of making my own space to set up a few display racks and reloading gear etc got me into thinking of possible "vault" ideas. My first thought was a shipping container as it will remain portable in future if we ever move. The only issue is that securing shipping containers against the modern age of portable angle grinders seems a bit of a hassle... sure there's all kinds of lock boxes and shrouds to protect the padlocks, but if I make the doors too secure then they'll just cut through the walls?

What can I do to secure the container as best I can against these kinds of attacks? Line the inside walls with aluminium plate to clog up the grinder blades, then plywood on top of that to attach shelving to etc?

Also looked at getting it half burried and then covered over with the front doors exposed and heavily reinforced, but further reading found that they don't hold up well against corrosion when burried unless heavily treated with special protectants that will skyrocket the price.

At the end of the day though, what the easiest way to get into someone secure storage? Smack the wife around a bit till you tell them where the keys are... though I guess the best defence is for the knowledge of what I own to be on a need to know basis.
