Using data on the Winchester 100gr. Super X Power Points, I see if you zero at 100 yards, it will drop 3.1" inches at 200 yards.
You'll be .2" or 1/5" of an inch low at 50 yards and at 150 yards it will be .9" or approx. 1" inch low.
So, if you aim at anything from 50 yards out to 150 yards, you can aim right at it(deer) with no thoughts of having to aim high or low.
Hope that helps.
