Ogorkiewicz notes in his "Technology of Tanks" that HESH must be fired at
relatively low velocities due to the thin shell wall. Max MV is typically
800 m/s. That might be a practical limit that has inhibited
experimentation. In principle, I could see a disadvantage from varying the
velocity either way off nominal (whatever it is), as this would affect the
timing of the fuze initiation vis-a-vis the configuration of the explosive
charge against the armor, meaning that the detonation would occur either
before or after the charge was optimally formed. As a rule chemical energy
rounds act independently of velocity. Higher velocity is desirable mainly
because it reduces time of flight/maneuvering effects against moving targets
and the effect of range errors.
