6,5mm Swedish

I have this cartridge which is obviously 6,5x55 Swedish but I wonder what it was used for.

The case and bullet are rivetted together at the neck. This has been ground back and the whole thing nickel plated. There is one hole in the case. The case is headstamped 19/N/12/M/

Is this a case made for an official purpose or is it something knocked up as an expediency?


Have a look at this site for Swedish military ammunition;
It appears very comprehensive and if your cartridge doesn’t appear - which it doesn’t - I’d suggest it’s probably not an official military cartridge.
