Abstract
A caseless formed propellant powder charge including a shaped propellant powder charge having a central continuous recess or hole and a percussion-sensitive primer charge with an H-shaped cross section disposed in the recess. Preferably, the shaped propellant charge and the primer charge are fabricated from materials such as nitrocellulose, polyvinyl nitrate, nitroguanidine, penthrite, or mixtures thereof, and tetrazene or tetrazene tricinate, respectively. The compression and dimensioning of the various portions of the H-shaped primer charge may be modified to achieve the desired sensitivity.
