A method is disclosed for modifying pre-existing ammunition projectile (10) which includes a hard metal inner core (11). The projectile is secured and a drill is applied to the tip end (17) of the projectile so as to create a bore (20) extending into the core. An insert (22) is then coupled to the projectile. The insert may include a shaft portion (23) which extends into the core channel and a tip portion (25). The insert is made of a non-hard metal or soft material.
