Abstract : An internally threaded igniter tube is threadably attached to a boss on the projectile base. In order to withstand ramming, a diametral flange at the base of the round engages a shoulder on the propellant so that when the igniter is in the assembled position, the midsection area is loaded in tension while the forward threaded section is loaded in shear. This arrangement produces superior ballistic properties by permitting the ballistic shot-start to be low enough to insure early motion while at the same time having the ability to withstand relatively high impact loads.
