If you are anything like I was about a decade back, all you needed to know about ammunition storage was ammo could survive the trip from your shopping cart to the checkout, and from the checkout to the range.
Ammunition had a short life as far as I was concerned, destined to be bought and promptly consumed in the chamber of a gun. I lived in Florida at the time, a very gun friendly state, and with ranges and gun shops on every corner, ammo practically grew on trees. Yep, planted right next to the oranges. You don’t need to stash what you can never run out of. After all, you can just buy more.
