The inert .50 caliber drill cartridge case, manufactured at Frankford Arsenal in the USA, is a non-functional replica designed for training and demonstration purposes. Constructed to the exact specifications of live ammunition, this case lacks propellant, primer, and projectile, ensuring complete safety during handling. The durable brass casing replicates the weight and feel of a real .50 cal round, making it ideal for military and law enforcement drills. The cartridge typically features clear markings and is often anodized or coated for easy identification. Its historical significance adds value to collectors and enthusiasts alike.
