I know that people frown on having Mil/MOA mixes but I look at it two ways. One the Millet scopes are all second focal plane scopes so it you want to range something or hold off the correct amount then you have to stop and think "Ok am I on the correct power setting", that, by the way, can be either 12X or 24X on the Millet. Two I have the Mil Dot Master calculator that I can easily convert between MOA and Mil. If you think that this will take too much time, I agree with you BUT I have not had many, if any, opportunities to shoot at an animal and miss then have it stand around while I adjust for point of impact. Usually they have kicked in the after burner and are out of sight before I even have time to get ready for the next shot. Even at the range I cannot see my point of impact right away because of recoil.
I just got a Vortex Viper PA with a Mil dot reticle and MOA adjustments. I might be asking for trouble and I am sure that people will think the same, but I am going to try it and see.
On a future note, when I get a rifle ready to shoot in the 1000 yard plus range I am going to get a LR-1 Mil/Mil scope.
