Just to save you some time, I have shot hundreds of hydrashocks in 9mm and don't find them to be any more impressive than anything else out there. I have used them on paper and on animals (to put down wounded animals, etc.) and they are certainly no magic bullet. If you are into hollow-points, in real life, any old hollowpoint is as good as the next.
with what I've read and seen there seems to be a slight improvement over standard HPs vs. the Hydra Shoks.
I just put some Winchester Ranger 9mm SXT, Remington Golden Saber and Federal HST on as well...still abit of the Federal HyraShok too.
Out of this list the Golden Sabre is BY FAR the best performer. That bullet opens up huge and reliably every time and no matter what you shoot it through or into. I have 5 or 6 that all look identical yet were fired in different tests on different days.
The SXT would be my second choice. Opened up they look nasty but for expansion size and penetration they really don't exceed the performance of other high end bullets.
