I assume that a "non mildot reticle" is a plex?
Leupold has offered 11 reticles in that scope; you've narrowed it down to 10.
I'd sight it in at 250 so you're good to go to 300 without having to think.
Or, as noted previously, you can add a turret. Kenton Industries makes one that installs easily and then you can dial in your elevation for any distance you want. Search on this site for more info about them if you wish.
