I like my mil/mil scope a lot, especially with the reticle in the front focal plane (this makes the subtensions on the reticle the same angular arc regardless of what magnification I'm using).

I find it a lot easier to use than using MOA and converting that to "inches at 100 yards" and then figuring out yardage to the target and multiplying "inches at 100 yards" times however many hundred yards I'm shooting ... groundhogs would die of old age before I figured out where to hold!

A handy ballistics calculator that will spit out firing solutions in mils or MOA is at:

Just input all your data and then get it to spit out a range card showing your holdover and windage values in mils and you're good to go!
