HST was originally a follow on to Hydra-Shok. It meant Hydra-Shok Technology.
Can you cite a source for this? I remember reading this was just something people assumed incorrectly.
dadillac- yes, from what I've seen and read, the HST bullet is a completely new design from the Hydrashok. Hydrashoks feature the post thing with non-bonded jacket, HSTs just have a hollow cavity with crimping to connect jacket and core.
What HST stands for, idk, but it's not HydraShok Two/Tech/Talon/Tactical/TryAgain
Might've been Hi-Shok Two according to a guy according to one of the design engineers, but the company's official stance is that it doesn't stand for anything.
