Now available on Ordnance.com: an exceptional offering of new old stock 20×110mm Hispano M18A3 Drill Rounds, each sealed in its original military-issue spam can, with the option to purchase a full crate of six. These rounds are completely inert and were designed for training and maintenance use with U.S. 20mm aircraft cannon systems during the Cold War and post-WWII era.

The M18A3 was a drill and function-testing variant of the 20×110mm Hispano-Suiza cartridge, widely used in U.S. aircraft cannons such as the M3 and M24. These guns were mounted on a variety of U.S. military aircraft—including the P-38 Lightning, P-61 Black Widow, and early jet fighters such as the F-80 Shooting Star—well into the 1950s and 1960s. The M18A3 drill round allowed armorers and ordnance crews to safely practice loading and unloading procedures, test feed systems, and train personnel without the risk of live ammunition.

Each sealed spam can contains 25 M18A3 drill rounds and is designed to resist moisture, corrosion, and environmental wear. Crates are available in varying condition—some may show signs of age such as faded paint, darker wood, or missing rope handles and latches. However, all spam cans inside are sealed and preserved as originally packed by the U.S. military.
