Underwood Ammo

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.

While taking advantage of our state of the art testing equipment, this high-performance ammunition is field tested using popular, real firearms that our customers are most likely to own out in the real world with all the elements you would experience.
