Every year US Armorment LLC participates in an ATK (read Federal) ballistics shoot for police officers. This year we actually cataloged the results. In the image below you will see the first column on the left which is bullets just fired into ballistic gel. The second and third columns are bullets shot through windshield glass and gel at a 45 degree angle, 15 degree cant. The object of the exercise is to see which bullet have the best expansion and weight and jacket retention through vehicle windshields and overall. It was no contest. Even the venerable Federal HydroShok failed to retain jacket and weight compared to the HST rounds. This is not a fluke. Overall performance mimicked last years results with the HST having the most consistent characteristics. Check everything labeled “HST” in the image. JG
