RE: sighting in a scope
To many variables to give you an anwser with any certainty. Only way is POI verification by shooting at the ranges and making the appropriate adjustment to obtain your desired zero.
If sighting in a fresh scope I'd start at 25 yards so yourtouching the top of the bull, then try 50 and finally 100 for fine tuning. If just checking POI or new load 1" high at 50 should put you in the ballpark for fine tuning at 100.
