My final adjustments to a scope are done the way I want to hunt and target shoot with them. When I shoot my Knight, I know the first hit will be two inches off the center of the bull. That's ok with me because I hunt on a fowled barrel. My White is the same way, first shot about an inch or more low, but the rest go into the bull. Again, I hunt on a fowled bore so that is fine. So I dial mine in on a fowled bore.
