I got the Fieldscope III ED 20-60x60 right before hunting season this year. Only had it at the range once, no problem seeing .277" holes @ 400 yards, thats all the farther we were shooting. Didn't have any problems counting points on mulies @ 2-3+ miles though. Did check out a bachelor herd of bulls at about 6 miles, but with heat mirage, couldn't count the individual points but could judge the frames. Hope this helps.
