I may be on the misinformed side of the table - please correct me if so - but don't you want a non-airtight container for storing ammo?
In the event of a fire, you'd be risking turning a metal container into a large grenade, would you not?
Myself, I use regular ammo boxes but drill a small hole into the top of the face. It's probably not much bigger than a 1/32" hole - just enough to equalize the pressure.
Vacuum food sealers work well for making "battlepacks"
An airtight container will not turn into some gigantic bomb. If your ammo is burning to the point of ignition, the airtight container is the least of your worries.I may be on the misinformed side of the table - please correct me if so - but don't you want a non-airtight container for storing ammo?

1500 rds of .308? If it were me, I'd get a 5 gallon pail, fill the bottom with silica crystals, load in the ammo, then use some caulk around the rim when you seal it in for the long haul.
I'm a bit curious though, why bother storing 1500 rds for long term? Most people would shoot it all up long before they had to worry about brass corrosion. I could see 15000, but not 1500.
You don't need to do that, the military ammo cans are designed to break along the bottom seals if the pressure inside the can gets too high, venting the gas.Myself, I use regular ammo boxes but drill a small hole into the top of the face.
