Abstract: The cartridge package (100) comprises an elongated housing (110) with a first 5 compartment (120) being divided into two sub-compartments (121, 122) with a flexible intermediate wall (117). Each sub-compartment receives a row (R1, R2) of cartridges (150). Opposite side walls (111, 112) of the housing are provided with a longitudinal slot (160, 162). A mouth portion (130) extending outwards from a top end (E2) of the housing comprises a second compartment 10 (135) having an open top end (E3) and being adapted to receive a mouth portion of a first cartridge magazine in order to load the cartridges from the cartridge package into the first cartridge magazine. The width of each longitudinal slot is dimensioned to receive an edge of a second cartridge magazine in order to push a respective row of cartridges from the cartridge package into the first cartridge magazine.
