Salmoneye-
It was def. Hydra-Shok. I don't think Vital Shok was even on the market then
He also had a tech there chronograph some of the 129 grain .38 Hydra-Shok for me, to use the data in an article. I was comparing snubs and three-inch barrels. I asked about the 158 grain .357 Hydra-Shok, also, as it was what I was carrying in my duty weapon then. We were discussing how it'd fare on humans, and he exclaimed that it was sure effective on deer. He had seen it so used, I believe, and gotten additional feedback from customers.
Personally, I don't think I'd take a raking shot on deer with a .357 unless the animal was pretty small, but for side-on shots, into the lungs or heart, I feel that it's an adequate load in the right hands, at reasonable ranges. And I think Hydra-Shok would be very effective. I have seen Vital Shok only in rifle calibers, but if they make it in .357, it's probably good, too.
Remngton has also made a 165 grain .357 round meant specifically for hunting. I don't know if they still make it, and currently shy away from that brand in both ammo and guns, due to quality issues. I have a box of it that I keep in case I ever find myself in bear country. It is not just a slightly heavier version of their 158 grainer. It is constructed differently.
