Mr. Howell,
That makes tons of sense. I always wondered about the terminology(sp?) and for some reason hydrostatic didn't sound right. Oh well, I'm not a scientist though.
On the subject of hydro (whatever) shock I have witnesses very rapid kills with my 243 and 100gr. core-lokts(handloaded). So impressed was my Dad(Dave in WV) that he bought a 243 for himself. Both of us have had favorable results in pushing 100gr. core-lokts at a guesstimated 2900fps.
