What is the little rod in the center of the bullet for? I got a box of .40S&W hydra-shok, and I am curious about it. I know a noob question, but this is a first for me.
The theory is that the post re-directs the hydrostatic forces out to the walls of the bullet increasing the probability of expansion.
The Hydra-Shok was an innovative design for its time. It didn’t quite live up to the theory.
The HST is the way to fly.
Thanks
i thought it was just to prevent plugging. perhaps that’s the new line, since the whole hydrostatic shock thing turned out to be a gigantic flop.
Originally they did claim it was for aiding in transferring the hydrostatic forces against the interior wall of the hollow point cavity and aiding in expansion.
As other’s stated, it was hot shit ammo back in the late 80’s early 90’s, but it’s been surpassed.
I still wouldn’t want to get shot with it, no sir, but there are better choices that allow for better barrier penetration.
Two of the LE Dept’s around here issued SIG P220’s with 230 gr. Hydrashok for most of the late 80’s and into the late 90’s, and they definitely did good work against the bad guys, but there was one case where a round was fired through auto glass and it didn’t perform all that well. Bad guy was still stopped, but about that time the dept’s switched to Gold Dot.
