Not trying to be a smart azz,But if you have the room at the place that you sight in at.You might would try 1.5" or ( me personally) a 2 or 3 " high @ 100 yards .then try backing up @ 50 yard increments until your shots are dead on or say 4 or 5 inches low which ever you like the best then you would know for sure without a doubt what your max range would be without any hold over just in case you should ever encounter that one shot over 150 yards that everybody gets eventually but does not think they will.JMHO
