To be really pedantic, the metal liner of a shaped charge does not melt, or is
not completely melted depending on the metal. It is put under sufficient
pressure that it is forced to act like an inviscid fluid. The speed at which
the jet moves (7km/s +) means the strength of the jet material does not matter.
It is moving well above the speed of sound of the jet and target materials.

Any more information on how that "plasma jet" works?
I think "plasma jet" is someone's overenthusiastic sloppiness. LSC is Linear
Shaped Charge, which will produce a jet of molten metal and hot gas, but
wouldn't (I'd think) be hot enough to produce plasma.
