Shellcase for controlling reflections of primer shockwaves
A shellcase body for use as part of an ammunition cartridge, which includes a base portion at one end, a middle portion having a substantially straight sidewall and joined with the base portion, and a shoulder portion joined to and extending from the middle portion. A neck portion may be joined to and extend from the shoulder portion. The shoulder portion is typically annularly shaped and includes a semi-circular sidewall that extends between an aft end and a fore end. The semi-circular sidewall has a curvature that is defined by a circular arc having a predetermined radius and a center that is positioned a distance away from the shellcase body center longitudinal axis. The shoulder portion is joined with the straight sidewall at a secant point of the circular arc, i.e., the straight sidewall defines a secant line that intersects the circular arc at the aforementioned secant point.
An ammunition cartridge includes: a basewad disposed within a tube proximate the aft end of the tube; a projectile wad disposed within the tube proximate a fore end of the tube; a propellant charge disposed within a chamber formed between the projectile wad and the basewad; and a projectile disposed within the tube between a forward facing surface of the projectile wad and the fore end of the tube. The aft end of the projectile wad has a powder cup skirt formed thereon, and a chamfer is formed around an outer perimeter of a lip of the powder cup skirt. The chamfer allows the powder cup skirt to be slidably received within a skirt of the basewad to form the chamber. The chamfer provides a clearance at the powder cup skirt lip, which helps to insure undisturbed entry into the mouth of the basewad skirt.
A projectile according to exemplary embodiments generally includes a jacket with nose, middle, and heel portions. The nose portion includes a forward cavity. The heel portion includes a rearward cavity having sidewalls. A dense core is within the rearward cavity and bonded to the sidewalls. Upon upset of the projectile, the portion of the jacket forming the forward cavity peels generally back toward the heel portion thereby forming petals, and the sidewalls and the dense core axially compress and radially expand to define a bulge portion, with the jacket material substantially covering the dense core material thereby inhibiting exposure of the dense core material to the upset media.

A sabot-retaining shotshell cartridge and firing assembly including a barrel or barrel insert for firing the sabot-retaining shotshell cartridge. The shotshell cartridge includes a cylindrical hull, a sub-caliber projectile, a propellant charge, and a sabot. A central pathway or thin membrane is defined within the base of the sabot between the sub-caliber projectile and propellant charge.

A neck portion may be joined to and extend from the shoulder portion. The shoulder portion is typically annularly shaped and includes a semi-circular sidewall that extends between an aft end and a fore end. The semi-circular sidewall has a curvature that is defined by a circular arc having a predetermined radius and a center that is positioned a distance away from the shellcase body center longitudinal axis. The shoulder portion is joined with the straight sidewall at a secant point of the circular arc, i.e., the straight sidewall defines a secant line that intersects the circular arc at the aforementioned secant point.
An ammunition cartridge includes: a basewad disposed within a tube proximate the aft end of the tube; a projectile wad disposed within the tube proximate a fore end of the tube; a propellant charge disposed within a chamber formed between the projectile wad and the basewad; and a projectile disposed within the tube between a forward facing surface of the projectile wad and the fore end of the tube. The aft end of the projectile wad has a powder cup skirt formed thereon, and a chamfer is formed around an outer perimeter of a lip of the powder cup skirt. The chamfer allows the powder cup skirt to be slidably received within a skirt of the basewad to form the chamber. The chamfer provides a clearance at the powder cup skirt lip, which helps to insure undisturbed entry into the mouth of the basewad skirt.
A projectileless ammunition system (20; 320) includes a metallic case (22; 322). A propellant charge (26; 326) is carried by the case and covered by an over-powder member (24; 324) in the absence of a separate projectile. The ammunition is advantageously used with an industrial ballistic tool operating so that each spent case serves as the effective projectile to be propelled by firing of the next round of ammunition.
