Abstract
A firearm projectile has a core extending along a central axis from a base portion to a tip portion, the base portion generally having a cylindrical shape and the tip portion comprising an ogive shape. A jacket encases the core along the base portion and the tip portion, the jacket having a shank portion defining a closed rear end and an ogive portion extending to an open front end. Protrusions extend into the core from an inside of the shank portion, the protrusions having a spaced-apart arrangement with each protrusion engaging the core to retain the core together with the jacket upon impact with a target.
