[Towertalk] Measuring/ calculating Inductance

I am looking for some advice or references on how to calculate and/or measure the inductance of a loading coil.  I have been modelling a loaded yagi (for 80m) and know the reactance I require for the loading coils, and want to design the coils.  I have experimented with a coil on a 6 '' form and have tried to measure the inductance with my MFJ analyser....the MFJ will not measure over 650 ohms reactance.  Is there another way to either accurately measure the inductance or calculate the winding required for "Y" inductance using "X" gauge wire on "X" diameter form?  I realize experimentation will ultimately be required but I'd like to get close on my first design.
