Collection: MJ Ammunition Collection – SAAF No. 4 Hendon, Australia

This collection features ammunition manufactured by MJ – Small Arms Ammunition Factory No. 4, located in Hendon, South Australia, one of the key Australian munitions plants active during the Second World War. Established to support the wartime ammunition demand of both Australian and Allied forces, SAAF No. 4 produced large quantities of .303 British and other service calibres. Rounds bearing the MJ headstamp represent the factory’s wartime output and showcase distinctive Australian manufacturing characteristics, including variations in brass composition, primers, and date markings. These cartridges offer collectors and historians valuable insight into Australia’s contribution to the Commonwealth’s wartime ammunition supply chain. Whether used for reference, comparison, or display, MJ-marked rounds serve as a historically significant component of any cartridge or militaria collection, reflecting the industrial effort and strategic importance of Australian ordnance production during WWII.
