A non-jacketed bullet including a monolithic sintered body and a sintered projectile tip. The monolithic sintered body includes a base portion and a deformed hollow nose portion, and the sintered projectile tip includes a base portion and a nose portion. A portion of the sintered projectile tip extends into the deformed hollow nose portion of the monolithic sintered body and a portion of the sintered projectile tip extends from a distal end of the deformed hollow nose portion of the monolithic sintered body. Also, a method of manufacturing a non-jacketed bullet including providing a monolithic sintered body including a base portion and a hollow peripheral portion providing a sintered projectile tip, inserting a portion of the sintered projectile tip into the hollow portion of the monolithic sintered body, and forming the hollow peripheral portion into the shape of a hollow tapered nose.

Metallic solid projectile for practice cartridges, in particular for use on preferably police shooting ranges, wherein the solid projectile comprises a front-side ogival portion and a cylinder portion for holding the solid projectile in a cartridge case and defines a projectile length in the axial direction, wherein the ogival portion has an ogival wall and a rotationally symmetrical ogival cavity circumferentially bounded by the ogival wall, wherein it is provided that a fully cylindrical stem portion of the solid projectile extends in the axial direction over less than 45% of the projectile length.

Various embodiments of projectiles are described. In one embodiment, a projectile includes a projectile core having a central recess formed therein, the central recess including a conical recess portion and a cylindrical recess portion. According to certain aspects, the projectile core may include a core base, and the central recess of the projectile core may extend from a leading circumferential rim of the projectile core to the core base along an axis of symmetry of the projectile core. The projectile core may further include projectile fingers each separated by a kerf, extending longitudinally from the core base to the leading circumferential rim, and extending radially apart from the axis of symmetry between an outer periphery of the central recess to an outer periphery surface of the core, and a nylon tip including a spherical nose, a conical taper portion, and a cylindrical anchor pin.

A duplex projectile cartridge system (e.g., 400) for use in a standard rifle (e.g., 10) has a front bullet (e.g., 320) and a substantially cylindrical back bullet (e.g., 440) coaxially aligned with one another. The front bullet's base is held in the cartridge case neck far enough to engage the back bullet's front surface so that the case neck simultaneously bears upon the front bullet and the back bullet. Optionally, the cartridge configuration orients the back bullet and defines one or more gas bypass lumens to allow expanding gas to initially bypass the back bullet and drive the front bullet distally to force an inter-bullet gap (e.g., “IBG” 480) upon firing.
