The earliest version had a load of 4.46 g of blackpowder, and a projectile weighing 21.85 g. This gave a muzzle velocity of 500 m/s. The later version, with a full metal jacket, was loaded to produce the same muzzle velocity.
All in all, more than 3 million cartridges were manufactured for military use in Norway, as well as more than 2 million ordered from abroad. The majority of these were sold with the Jarmann rifles when the Norwegian Army introduced the Krag-Jørgensen.
