Inert British .303 Round – KN 1917, Kings Norton Metal Co.

This is an inert British .303 rifle cartridge, manufactured in 1917 by the Kings Norton Metal Co., Birmingham, and marked with the KN headstamp. Early-production KN rounds are highly sought after for their pre–First World War manufacture and distinctive case markings. This 1917 example offers excellent historical value, representing ammunition used during the development years of the SMLE (Short Magazine Lee–Enfield) rifle. Fully inert and safe for display, it is a desirable addition for collectors of early .303 ammunition, British ordnance historians, or those building a comprehensive headstamp reference collection.
