A MIL is 3.43 MOA and the knobs are 0.1MIL per click. The neat thing with MIL is that you can zero at 100 yards then set the knob at 0 for that distance. Next, go on JBM or whatever you use and work up a come-up chart in MIL. Now, you just dial the number on the elevation knob that corresponds to the distance and fire away. Disl back to 0 to get back to 100 yards.

I'm an MOA guy, but sometimes I pull out my PRS rifle with the MIL scope and go play. In one complete revolution, I can go from 0 to 900 yards, just clicking to the number I need for the distance. It makes it easy for this old guy.
