Sweden and Norway both adopted the 6.5X55mm as a military round. The Swedes, of course went with the Mauser design, the Norwegians went with the Krag design. They shoot the SAME round. If you check out the DeHass book on Bolt action rifles, there are pictures of the Norwegian and US Krags, that show how they differ. Some handloading manuals also mention the Norwegian Krags in 6.5X55.
They are also mentioned in "The book of the Rifle", about how after they were no longer used by the Norwegian miliitary, target shooters still desired them.
Also, in the old book about the Springfield 1903's, in the sniper section, mention was made that the Nazi's reported the Norwegians used the Krags out to 1000 yards ( I think it was ).
The Norwegian Krags were made at the "Kronsberg"
arsenal, and are so marked on the receivers.
