Underwood .50 Action Express Ammunition 300gr Full Metal Jacket Flat Nose - #509 (20 Rounds)

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.

As with all of Underwood Ammo™ rounds, we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.
