Thanks for the info. I haven't tried the benchrest fixed Leupolds, but have been told by top benchresters of the "problems" getting the last few hundredths of an inch in group size. I do have a Mark 4 10x on one of my hunting rifles and so far it has worked very well. Time will tell!
My wife likes even more magnification in hunting scopes than I do, and has been switching over to the 8x36 M8 when she can find them. I kinda wish they made an 8x42 FX-III or something like that, but also doubt there's much of a market for one!
If I had my dream, pre-64 300 H&H, the scope you just invented would be my first choice.
