Update:

So I mounted the new SS 3x15 on my rifle and went to the range yesterday for a sight in. I have been doing my homework on the Mil reticle and I wanted to sight in at 100 yds. My first shot was on paper but several inches to the left and a little high. I centered the reticle on the target and the first shot was almost exactly 2 mils left and about 1.5 mils high. I adjusted the turrets and my second shot was bulls eye. I then began hitting metal at 300-400 yards consistently and ran out of light before I could run out farther.
My takeaway with the Mil reticle is not to over complicate it. I downloaded the "Shooter" app and have changed the settings to MIL from MOA in the app so that data was quite helpful with making turret adjustments out past 200 yds. The SWFA scope itself seems very durable and tracks quite well. The glass isn't the greatest but is more than enough to serve the purpose I am using it for.

Thanks to those who made constructive comments.
