Interesting cartridge

I was recently in Norway, Rjukan (which has quite colorful history and I found a cartridge, which could be possibly from WW2.
I wonder if this community is able to identify this found.

This is a Norwegian 6.5x55 cartridge case made at Raufoss Patronfabrik in 1922. If it was fired during WW2 is anyone’s guess.

Thank you very much for this information.
