I guess Ill chime in agan, hydrostatic shock is the term used for the wound channel created by the design of the bullit, all bullits create hydrostatic shock. Many factors make up a bullit and what it does to the material it hits. To start, the design of the bullit; FMJ, Soft point, protected point, Ballistic tip and ets., next you need a powder charge, a charge designed to get the bullit downrange and at the correct velocity to make the bullit do what it was designed to do, expand, fragment, yaw. The firearm that its shot from also changes the effect, 16" bbl, 18" bbl, 22" bbl, 26" bbl, if thecartridge is designed "reloaded"to be shot from a 26" barrel, exterior ballistics will change dramaticly if shot from a 16" bbl and the hydrostatic shock will be lessoned greatly. To get back to the original posters question, increasing velocity on one perticular bullit can do good or bad, it is the design of the bullit that determine it, will it increase the hydrostatic shock on an animal, possible, will the bullit function to its design, maybe, but when your talking 3 to 400 fps, will it kill an animal any quicker than a bullit traveling slower, NO! Shot placement is the main thing that determines how quick an animal expires, if I could get away with it 100% of the time, I would make them all head shots, then I wouldnt spend hours trying to come up with a better bullit to shoot!.
