At the most basic level, ammo cans are containers that protect ammo during transport and storage.  The ammo cans offered for sale on cleanammocans.com were used to transport ammo from the manufacturer to the customer, where the lids were only opened to remove the ammo before being closed and discarded. Our cans have never been to a shooting range, banged up in the bed of military vehicle, or stored outside in the elements before being auctioned like similar military surplus ammo cans.
