I just saw an article, on another gun site, comparing the different HPs.
It seems to me that the Hydra Shoks are real speed sensitative. About one third did not even open up even when good velocities were reached.
The gold sabers, gold dot, corbons looked great. This is about the third time I've seen evidence that the Hydra-Shoks failed to do what they were supposed to do. The Salem Oregon PD is changing from Hydra Shok to ??, because they failed to open up even after going through a perp, three sides of dry wall and a stud.
I used to be a real Hydra-Shok man but I'm thinking Corbons, or Gold Sabers from now on.
