That may be out there in cyber land.... I'll surf around some...
I think I could extrapolate the internal box dimensions by the cartridge boxes in the pack.
Then assuming you are using 3/4" dimensional lumber, the outside Dim's.
I come up with 14" wide X 16" long X 6 3/4 " deep, outside dim's (use 3/4" Top & bottom = 8.25 " outside)
allowing for 44 boxes of 20 (880 rounds tight). this an extrapolation.
You might want to cut a bit of + slack ( a tad oversize allowing for thickness of the boxes...
However, if you
aren't planning
to pack as the photos show, and just a prop box the above Dim's are adequate. (
880 rounds and quite heavy)1000 rd. stenciled on the original crate... I calculated @ 880 rounds.
Maybe St. George has a response, Robert?

FYI... if you are planning to finger joint the corners. allow accordingly
hope that helps...I'll like to see it when complete
