Abstract

A projectile load, such as a projectile cartridge, can include a propellant within the case. The propellant may include a first face, and the projectile load may include a form having a predefined set form shape that holds the first face in a first face shape that is uneven, which may include one or more protrusions and may define one or more hollows. The projectile load can also include a projectile at least partially within the case and different from the form, with the first face of the propellant facing toward the projectile. The projectile load can be configured so that an ignition of the propellant will force the projectile out of the case.
