Help Identifying a pistol cartridge EC .42

Looks like a .45 ACP but is marked differently. … 4328050826 … 4328050826

This is a normal 45ACP cartridge with steel case made by
the Evansville-Chrysler Plant in 1942.

I copied the correct link, so you can see the pictures


Thanks René. I had myself and a couple of friends scratching their head over this one. I had just put a micrometer on it when I saw your message. Saved me a lot of work.


There is web copy of “Bullets by the Billion” here:
It tells the story of the manufacture of steel-cased .45 and .30 Carbine ammunition by Chrysler during WWII.

Great! I’ll pass it on to my friends as well.

Thank you,
