US Cartridge, 105mm HEP, HEP-T, M327 (T81E28)
This cartridge is used for both anti-tank and anti-personnel purposes.
The projectile is a thin walled steel cylinder with a relatively short ogive and a flat base. A gilding metal rotating band encircles the projectile slightly forward of the base. The base is fitted with a threaded adapter which accommodates a base detonating fuze which may or may not have an integral tracer, depending on the model. Rounds with tracers are classified as HEP-T. The projectile is loaded with 7.6 pounds of Composition A3. An M14 series cartridge case, containing a non-adjustable bagged charge of single granulation propellant, is loose fitted over the base of the projectile. A percussion primer is press fitted into the base of the cartridge case.
