Abstract A magazine for holding a number of cartridges containing flares, metallic chaff and the like for aerial dispensation. The magazine has a simple open frame or shell in which any required number of cartridge holding tubes are positioned in a specific pattern on a prepared tool, the tubes being initially held by a layer of rubbery material which forms one finished face of the magazine. The interior of the shell between the tubes is then filled with foam material, applied progressively with the assembly in a special holding fixture to ensure complete filling.
