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.

The invention relates to a lead-free partial fragmentation bullet comprising a bullet jacket, a rear core compressed therein, and a nose core compressed in the ogive region, wherein the tip core sits on the rear core. In order that the rear core does not separate from the contacting bullet jacket upon striking a target body and to thereby guarantee a sure exit wound out of the target body, a predetermined breaking point is proposed which is arranged between the rear core and the nose core. The rear core has a molded recess on the end thereof facing the nose core, the end of the nose core facing the tail core fills in said recess, and the bullet jacket has a peripheral break away edge on the outer circumference in the region of the predetermined breaking point.

The invention relates to a Pb-free deforming/partially fragmenting projectile with a projectile body. In order to improve the killing effect of the projectile, the projectile has a fragmenting core according to the invention. The projectile body is equipped with a bore which is arranged on the longitudinal axis, extends from the tip of the projectile body, and extends into the interior, and the projectile body tip, which faces away from the projectile base has a bevel which extends from the outer circumference of the projectile body to the bore and runs at an acute angle to the longitudinal axis. The fragmenting core has a cylindrical part and a head part. The cylindrical part is arranged in the bore, and the head part protrudes out of the bore and has a support surface which is adapted to the bevel in the projectile body and together with the support surface rests on the bevel of the projectile body. The head part has a rounded tip which forms the tip of the projectile.

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 bullet (10) including: body (11) with a base (12), a distal end (13) with a mouth (14), and an interior cavity (34) recessed into the body from the mouth; an insert (40) configured to be held in the interior cavity and to protrude from the mouth; and at least one skive (50) formed in the distal end and axially overlapping the interior cavity relative to a center axis (16) of the body. The interior cavity is configured to permit limited axial recession of the insert into the interior cavity when the insert impacts a hard target. The limited axial recession opens a pocket (80) between the insert and the mouth.
