US Cartridge, 106mm Dummy, M368
This cartridge is used to train gun crews in loading and unloading ammunition for 106mm recoilless rifles.
The cartridge simulates HEP-T Cartridge M346A1, but because it is a drill round is completely inert and contains no propellant. A dummy cartridge case is crimped to a dummy projectile, and the components are further connected by a metal rod threaded into the base plug of the dummy projectile on one end and onto a dummy primer in the base of the cartridge case. A pre-engraved rotating band encircles the dummy projectile near the base for engagement with the barrel rifling of the weapon.
