I know little about hydrostatic shock, and don't really enjoy dissecting the minute details of this sort of stuff. I can relate somewhat to shock, just by way of hunting a lot. The hog below was shot by me last night, and was shot straight up the snout...breaking both jaws and there was enough energy there to make one eyeball pop right out of it's skull. I was using my 6.5 Creedmore and I would definitely say there was some type of shock inside it's skull !
Given that hydrostatic shock is the remote wounding of structures and you placed the bullet up the snout, then is likely to have occurred here is the overpressure from hydraulic shock, which is localized (think temporary wound cavity).
IMHO, hydrostatic shock does happen at higher velocities and more so with expanding bullets. Expanding bullets not only make a bigger hole, but disperse their energy while expanding and that energy is dispersed into the tissue. If one butchers their own game, hydrostatic shock is readily apparent anytime bone, and/or heavy muscle is hit.
That is hydraulic shock.
From the article cited above...

Hydraulic shock is the civil engineers term also known as water hammer but in terminal ballistics context refers to the pressure of accelerated fluid particles that create the temporary wound channel.
Hydrostatic shock transfer refers to the effect when shock waves travel through flesh to distant nerve centers, disrupting their ability to emit electrical impulses.
