It has been my experience with my Encore and (and I can show you the paper targets to prove it) that I will inevitably shot low on shots 25 yards and in. I know physics says no, but I can shoot at 25 yards and be 2-3 inches low (3 shot groups), be 1inch high from 50-100 (3 shot groups) and be zeroed at 125 yards. Gun has always performed that way. Come to think of it my old 45cal Hawken would do the same thing.
