If you have access to a bench power supply, or any other source of constant current (an LM317 regulator in constant current mode, for example) just pass a current through the item you're measuring, and measure the voltage across it. For example, at a current of 1 amp, a meter set on its millivolt range will give the value of the resistance in milliohms.
In fact, the current doesn't necessarily need to be very well-regulated, if you have a way of measuring it precisely with one meter while you measure voltage with another. Ohm's law is a wonderful thing.
