M51 Krag Jørgensen elgrifle (Moose rifle).
This rifle replaced the M48 in 1951. Almost identical, but some
small modification was introduced. There are no wood on top of
the barrel, there are a new rear sight, the bolt handle is round,
not flat and some more minor details. Both the M48 and the M51
was built with 7,92 barrels. After a few years, they found out that
the standard 7,92x57 ammunition was a bit too hot for the Krag action. Norma then produced a lighter ammunition that they called 7,92x57 moderate. This ammunition is about 10% weaker than standard 7,92x57 rounds. This ammunition went obsolete within not so many years.
