Description

This cartridge is used to deliver a concentration of antipersonnel grenades.

The complete round consists of a projectile, a modified fuze, and a cartridge case, The projectile contains six layers of grenades with three grenades in each layer. Three of the grenades in each projectile contain a bag of yellow dye for spotting the burst. The grenades are contained by a base plug attached to the projectile with three shear pins.

A mechanical time superquick fuze incorporating an expulsion charge is installed in the nose of the projectile, and may be set to function at any time between 2 and 75 seconds. The modified fuzes incorporate an expulsion charge and are not interchangeable with unmodified fuzes of the same model. The cartridge case contains a percussion primer and a propelling charge divided in increments to permit adjustment for the desired firing charge. The lip of the cartridge case is a free fit over the base of the projectile.

The projectiles are painted olive drab. There is a row of yellow diamonds 35 millimeters (1.38 inches) from the base of the fuze. Markings (stenciled in yellow) include nomenclature and type of filler. The M413 projectile was previously marked 105 H, COMP B, SHELL T-377EI and did not have the antipersonnel identification marking.
