Abstract: A bullet (100), having: a main body (102) with a bore (106) bounded by a sidewall (124); an insert (104) that is disposed in the bore and that has longitudinal splines (460) configured to form a longitudinal flute (4620 in the insert and to provide radial support for the sidewall of the bore. A leading end (466) of the flute is open.

Abstract: 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.

Abstract: A bullet tip comprises a body having a tail section and a nose section, the body composed of a partially sintered powdered metal, wherein the nose section comprises an ogive shape, wherein the tail section is configured for insertion into a cavity in a bullet main body, and, wherein the bullet tip is configured to fragment upon impact while exhibiting a penetration capacity of at least 800 joules.
