i have the illuminated one and so far i like it i have it mounted for use on either one of my white bison rifles i have the warne q/r rings and love those as well ! you can adjust or sight in based on two or three pellet loads there are little symbols on the scope for that so when you sight in based on one or the other you just turn the dial to that hash mark or you can do a custom sight in as the manual describes i am on the other hand going to develop my favorite load then sight in dead on at 100 yards and record where i'm hitting at other yardages on those different aiming points and just tape it to my stock or somewhere where i can get to it in a hurry. hope i helped a little ??
