.308 Norma Magnum cartridge was created by Nils Kvale at Norma, Sweden. Like the more substantial .358 Norma Magnum, it is based on the .300 H&H Magnum.
The length of the case is the longest that would fit in a standard Mauser action. It was soon superseded in popularity by the .300 Winchester Magnum.
The first and one of the few manufacturers to offer rifles in .308 Norma Magnum was Schultz & Larsen of Denmark, and they still are.
Its short powder column gives it an edge in efficiency over most of the older.30 cal magnums, not including ultra magnums or WSM caliber.
The longer neck helps with seating longer/heavier projectiles better than, the shorter necked 300 Win Mag.
