Defence Industries Ammunition Collection – DC Brownsburg, Quebec

This collection features ammunition manufactured by DC – Defence Industries, located in Brownsburg, Quebec, Canada, an important Canadian ammunition plant heavily involved in production during the Second World War. Known for its reliability and high output, the Brownsburg facility supplied vast quantities of .303 British and other calibres to support Allied forces across Europe, Africa, and the Pacific. The rounds in this collection highlight the factory’s wartime manufacturing variations, including differences in dates, load types, and headstamp markings typical of Canadian production. Each cartridge provides a valuable reference point for collectors and researchers studying Commonwealth ammunition supply during the 1940s. Whether used for display, comparison, or historical research, DC-marked rounds remain a significant part of Canada’s military and industrial heritage—an essential addition to any serious ammunition or militaria collection.
