The firing range was an open field approximately 5.17 acres in size surrounded by forest. The range was used between 1969 and 1971 during the Viet Nam conflict to test the 40mm cartridge. The rounds tested may have included both the M407A1 practice round and the M406 HE round. The practice rounds contained yellow marker dye, M9 propellant, and RDX booster pellets, while the M406 HE round contained Composition B and M9 propellant. The purpose of the range was to perform acceptance tests, which included muzzle velocity measurements and impact function tests. Approximately 2,500 rounds were fired at this range.
