Military history
The cartridge was developed in Denmark in 1888 by necking-down Danish 11,4x51R
Sporting use
Surplus military rifles have been used for hunting; and ammunition was manufactured in Otterup and by Norma Precision after World War II. Documentation is scarce for the design pressure specifications of these surplus firearms. Although modern weapons may have been designed for smokeless powder loadings, their similarity to arms designed for gunpowder loadings causes uncertainty about the safety of firing modern cartridges in weapons lacking proof test documentation.[3]
