How Far Will a 9mm Kill? Part 2
This video tests the terminal ballistics of Federal HST 124gr 9mm ammunition fired from a Kel-Tec Sub-2000 at 440 yards. A baseline test at 7 yards confirmed excellent expansion and 13.5 inches of penetration. Surprisingly, the 9mm HST projectiles still expanded significantly at 440 yards, demonstrating its viability as a self-defense round even at extended distances.
