This video provides a detailed ballistics test of the Underwood 9mm HERO 70-grain solid copper expanding hollow point ammunition. The instructor, with apparent expertise in firearms testing, evaluates its performance in ballistic gel after firing from two different barrel lengths: a 3-inch Canik Mete MC9 and a 4.5-inch Glock 17. The test focuses on velocity, expansion, and penetration, offering a critical assessment of the ammunition's effectiveness for self-defense.

Quick Summary

The Underwood 9mm HERO 70-grain ammunition features a solid copper expanding hollow point design. While it demonstrated excellent expansion in ballistic gel tests, achieving velocities of 1649 fps (3-inch barrel) and 1783 fps (4.5-inch barrel), its penetration was limited to 9.5-10.75 inches, falling short of the 12-inch FBI standard.
