I know this get asked all the time, but I could not find any back posts on this specifically. I have narrowed down my scope choide at this time to a Leupold 3.5x10 long range tactical mildot, with either the M1 dials or the M3 dials. What is the pro's and con's here? How precise can you get with the 1moa elevation dials on the M3? Groundhogs at 600 yards??? Thanks for any help here!
