Metal cans, make sure the rubber gasket is good no cracks or splitting - also check to ensure no rust - keep them up off the ground and put at least 2 small desiccant packs in with them - if at all possible keep them in a place in your house or garage that remains a stable temp no crazy swingsSuggestions on storage options please. Wanting storage for many, many 50 round boxes of 22lr. What ammo cans fit these boxes the best?
Thanks in advance
Plastic ammo cases also work just fine- same rules apply, however, with the MTM follow the factory rules regarding weight.
Have kept ammo for over 30 years to date with multiple methods, even bare on shelf in relatively stable climate controlled area without much issue.
