The miliradian system and the metric system share a common denominator: they are both base 10 , using 1/10ths instead of 1/4s like MOA or IPHY.
Being a base 10 system is where their similarity both begins and ends...
How to use mrad?
Make a dope chart in mrad.
Range target with an LRF, or use mildot master to SWAG it.
Dial turret to your dope, figure the windage, hold & fire 
If you miss, use your reticle as a ruler and correct for the second shot accordingly.
IN short, using mrad is no different than any other unit of measure. The application is the same, mrad just simplifies the dope values and the base 10 system is inherently easier to break down the reticle & target subtension. For me, at least...
