Dan, it sounds like many people are using the same ammunition containers.
Here's a tip.
Harbor freight sells the small 1 with the lid gasket For $4 pretty regularly I use those for I waterfowling.
They take spray paint well,They give you a dry place in the boat To store your cartridges.
The larger Boxes with the storage in the lid are great if you shoot multiple gauges
You can Paint The top and label them as you wish.
I also use 1 for toting dog stuff keeping it in the truck.
Collars leashes batteries Medical supplies, and some boxes of non tox in the bottom.
Being modular makes mobilization quick.
Pick a gun
Pick a box
Grab the duffel
Gone.
