Inert .303 Round – 1929 Dated CAC | Collectible Ammunition

This original inert .303 British Mk VII ball round, dated 1929 and manufactured by CAC (Colonial Ammunition Company), is a highly sought-after example of interwar Commonwealth ammunition production. CAC—operating factories in both New Zealand and Australia—was a major supplier of .303 cartridges used throughout the British Empire. The “CAC 29” headstamp clearly identifies its early 1930s manufacture, a period when significant quantities of .303 ammunition were produced for training, reserve forces, and growing defence commitments. During this era, the .303 British cartridge remained the standard ammunition for classic service weapons such as the SMLE Mk III rifle, Lewis gun, and Vickers machine gun. This round has been professionally deactivated to UK legal standards, ensuring it is completely inert while retaining its original components and external appearance. Collectors particularly value CAC rounds from the 1920s due to their relative scarcity, distinctive headstamps, and connection to pre-WWII Commonwealth military development. This 1929 example is ideal for cartridge boards, interwar collection themes, displays focused on Australian or New Zealand forces, or for pairing with period-correct rifles and kit.
