A small oddity...

It's possible that the bullets were pushed together as an 'experiment' but couldn't be extracted again so the whole thing was lobbed.

Could be they were pushed together in a moment of boredom and then left for a bunch of curious folk in the future to wonder what might be inside.
Ever walked in to an auction or shop and see a box - first thing you want to do is a open it to see what's inside

Will have to look at what I have again, from memory I've only got PC & LC. Other factories did repack but not aware it involved production during wartime.

The Evansville factory manufactured watertight packs, to replace the old card packs, which would be better withstanding in the humidity of the Pacific theatre.
I just had a quick look on the International Ammunition Association forum and found this thread on the factory repacks, as you mentioned, but one of the chaps halfway down shows headstamps of his wartime .30 Carbine’s with other makers.

Come to think of it, I think I might have somewhere the bottom section of a WCC .30 I found back when I was 11/12.

Best regards,

Useful post Simon, thanks. Will go through what makers I've found when I get a moment.
