The HST question has been answered. But in general you won’t see bullet / jacket seperation in standard Gel tests like bare gel or 4 layer denim. You normally only see it when shooting through intermediate barriers made of harder material like auto glass, auto body materials, etc.
My agency issues HST in 40 and Gold Dots in 9mm and .38. They work. Our last big purchase of Winchester Ranger 9mm incuded multiple lots with dud primers. As a result we had to relegate it to training / practice ammo. No matter how good tne Ranger /Talon bullet is they don’t do me any good if the rounds aren’t reliable.
