Trying to make an overland cocktail carrier

[RoarinDave]

I have an idea for an overland cocktail carrier, but I keep getting stuck almost in the start. I have a couple 50 cal ammo cans, but they are too small. Ideally, I need something about 2.5X size. I want to be able to be tall enough to have bottles in bottom, with a deck above that with all the mixology tools and shot glasses. But my idea can't get off the ground because I can't find an ammo can big enough. Perhaps I'm not looking in the right place, can you help me please?
