FMJ-FN bullets are non-expanding, powerfully penetrative bullets that are designed with your woods defense needs in mind; whether fending off wild hogs or black bears, the FMJ-FN bullets are consistently effective in taking down any wild animals that you may encounter.In contrast to the round nose non-expanding bullets, the flat nose bullets are able to pierce through dense bodies of mass while maintaining their nose forward position; the nose forward position is optimal for maximum penetration.
