45 shotshell M12 EC headstamps


I have these two .45 auto M12 shotshells, both with the EC 43 headstamp. One is large letters, and one is small letters. Anybody know the story with that? Is it just different equipment?



In my own humble opinion it’s simply different bunters. It doesn’t indicate anything, as far as I know. It’s common on other US Military cartridges from other Ordnance Plants during the WW II era. Also encountered on Commercial cartridges going all the way back to the beginning.

A purist headstamp hunter may possibly put some value on them but I’m not sure which one would be more valuable. Just another collecting field. Not nearly as exciting as collecting 9mm or 7.62x39.



You will find a very, very, large number of bunter variations in EC .45 M1911 headstamps from the war years (in both steel and brass case). Perhaps 25 or more?
When you start to include tracer or shotshell variations it could add perhaps 1/3 - 1/2 more? Just a wag.


Some variant found in France (headstamps, materials)
