About

What it is, and why it matters

Copy a link to this section

The Krag-Petersson M1876 was a lever-operated repeating rifle designed by Ole Herman Johannes Krag and Axel Jacob Petersson, and the first repeating rifle adopted by a Norwegian armed force: the Royal Norwegian Navy. It used a Peabody-type pivoting breechblock in which the externally mounted central hammer doubled as the operating lever, fed from a tubular magazine under the barrel and chambered for the 12.17×44mmR rimfire cartridge.

The Krag-Petersson is the rare design that successfully bolted a repeating tubular magazine onto a Peabody pivoting-block action, borrowing a Remington-style hammer, a Peabody block and a Vetterli magazine, but its hefty 12mm cartridge was already a generation behind when it entered Norwegian naval service.

Manufacturer attribution is mixed across sources, which variously credit Carl Gustafs Stads Gevärsfaktori (Sweden), Carl Johans Værn in Horten, and Kongsberg. Magazine capacity is reported as 8 or 10 rounds. Considered a practical disappointment as contemporaries moved to smaller-bore cartridges.

Trajectory

What the round does downrange

Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
