Did It Do It's Duty? Hornady 9mm Critical Duty, Ballistic Gel Test With The Taurus GX4!
This video details a ballistic gel test of Hornady 9mm Critical Duty 135-grain ammunition fired from two different barrel lengths: a 3-inch Taurus GX4 and a 4.25-inch P80. The test measured velocity, penetration, and expansion, revealing that the Critical Duty round achieved significant penetration but minimal expansion across both barrel lengths. The presenter notes the Critical Duty's design is geared towards barrier blind performance rather than maximum expansion for personal defense scenarios.
