You can create your turret tape or custom turret to show moa or mil if you want. Then when outside of the parameters your turret was made for you can still use a dope taped on your stock or ballistic app for your current conditions. But for hunting within your average parameters it works. I'd never shot my brother-in-law's rifle but for certain reasons I used his rifle for my elk hunt. Before the hunt I was shooting out to 600 yards using a custom turret. Ranged, adjusted, hit.
