Heavy Bone Test | Hard Cast VS FMJ 9mm Underwood 147gr +p VS Fiocchi 115gr FMJ
This video conducts a comparative heavy bone test using two 9mm ammunition types: 147gr +P Underwood hard cast and 115gr Fiocchi FMJ. The test aims to evaluate performance differences, particularly penetration and deformation, in unfrozen beef ribs. The presenter notes unexpected results, with the lighter FMJ round achieving slightly more penetration than the heavier hard cast load.
