6,5 x 55 mm - headstamp ID

I have seen some fired cases with this hds " C.A. 6,5 x 55 "

Any input about the maker that is unknown to me?


The headstamp “C.A.” stands for Century Arms, a large arms and ammunition importer in the United States. I think the cartridges were actually made by Norma, in Sweden. There is a “C.A.” headstamp on 9m/m Browning Long pistol cartrides as well, and perhaps others I don’t collect.

Thanks John
