Best scope for 5-700yd varmits?

[32Spcl]

Thanks guys, I'm almost confused, maybe just a bit more..or maybe it's all the Ice falling on me in Central Texas this week.

Ok, I believe I know the basics on the mil dot; in that after estimating the range , one would use the same rect. for hold over and windage after consulting drop charts.

But I'm not clear on using MOA. . .. Using Clicks ? to adjust MOA? Using a rangefinder, One would dial in the drop AND windage to zero out the rect. on the point of impact without actually holding over??? is that right?
If I outlined the Moa system correctly, in chosing a recticle, One would only need a cross or dot. , you wouldn't need hold-over dots and windage dots could be used or just dialed in.
So if that is right ,
How would one know if turrents are for mils or Moa?
I'm Looking a a Leupold 6.5X20 . Didn't see any options on turrnets, only recticles.
Overall the MOA system seems faster than using the the mil dot, but has the extra expense of the rangefinder.

Thanks again
