9MM Hornady XTP +P Ballistic Gel Test Various Barrel Lengths
This video conducts a ballistic gel test of Hornady American Gunner 9mm XTP +P 124-grain ammunition fired from firearms with varying barrel lengths (3.3", 4.5", 7.5", and 10.5"). The test aims to observe the impact of barrel length on velocity, bullet expansion, and penetration depth in 10% ballistic gelatin. Results show significant expansion and penetration across all barrel lengths, with some surprising outcomes regarding wound cavity size and penetration depth between shorter and longer barrels.
