I have the sme problem with my 40-70BN 2.1" C.Sharps. Nobody on Shooters.com seemed to have an answer other than shooting at a vertical target at 100 yards and looking for groop size rather than point of aim. Doesn't work when thinking of shooting at shorter ranges regurlarly, though. My fustration is that few if any front sights list their height, and there seems to be no standard way of talking about this. Height above bore is dependent on thickness of barrel. Height above base of dovetail seems the best, but I don't know any manufacturer who lists this.
