As long as the connecting leads can handle the current and are "low"
resistance, the resistance of the leads makes no difference to the
measurement.


Swapping leads on my various DVMs - using what appears to be decent
quality leads - will give different resistance readings for very low
values. Try it.


The connecting leads referred to are clearly those to the shunt, hence
the reference to the current rating. They make no difference to the
reading across the shunt for a given set of test leads and DVM.


Well, yes. But my point is in practice they will make a difference.
