^^ That's the exact safe I have, bought it from Tractor Supply ^^
Like everybody else discovered, it's now too small and I don't have even a modest collection. The entire top shelf is filled with ammo boxes (had to make a 2x4 strut to prop the shelf up) and the other shelves are also full of ammo.
My safe is bolted down and it would be quite a project for thieves to haul it off or break into (but never underestimate them!)
