Abstract
An improved geometric propellant loading configuration for high velocity, large or medium caliber projectile ammunition is disclosed. The propellant system includes several mutually contiguous extrudable stick shapes that in concert result in highly efficient use of propellant load space. The system reduces loading, assembling and packing (LAP) labor and overall cost, yet provides a dense pattern to increase propellant load and high perforation to improve burning progressivity over prior stick loads and more reliable and improved ballistic performance.
