Just like the subject says - Can 3 Romanian 75 Round Drum Magazines in Chinese drum pouches fit into a Fat 50 Cal Ammo Can.

Understand the dimensions are 12" long, 6.75" wide and 8.5" tall.  I tried to mock it up with some cardboard.  I'm looking for an airtight way to store the mags as right now I have them in a refinished old 7.62x54r Czech lightball box.

Thanks for the help!

seems like actually getting a can and trying it would be easier than drawing a 2-dimensional outline and asking on the internet.

barring that, try some hardboard from lowe's and make a mock-up box the same size.  just because they'll fit on the footprint doesn't mean they'll fit in the volume.
