Hahaha!...I scrolled on down thinking eventually I'd see something about zeroing instead of grubs, but I was wrong.
As for zeroes, you zero for whatever range at which you normally shoot, and know holds for other ranges, and no matter what charts say, you don't know any of that until you put it on paper at those ranges. Charts are good to get you on paper, most times, or at least some of the time.
