(General method of measuring)
This measuring method is used for most African species with horns except for those where a special measuring method exists.

LENGTHE OF HORN
Measurement is taken all along the front curve of the longest horn, starting at the lowest point on the forehead up to the tip of horn (A-B).
NB: Measurement is taken in a straight line along the top of the ridges of these horns with symmetrical ridges such as Waterbuck, Blesbuck, Impala etc. The measuring tape is therefore not pushed into the hollow curves in between the ridges. If the tip of a horn is broken or when it is worn round, the measurement is taken to a point at right angles to the highest part of such a tip. (See illustration D)

CIRCUMFERENCE AT BASE
Measurement is taken at right angles to the axis of the thickest horn, as close as possible to the skull (See illustration).
NB: Should the horn leave the skull at a sharp angle, this measurement will therefore not be an elliptical one. Don’t necessarily follow the lower edge of the horn.

TIP TO TIP
Measurement is taken in a straight line between the tips of the two horns(C-B).
NB: Indicate by means of notation should on horn have been broken in such a way that it will affect this measurement.

RANKING
Ranking in the list is determent by the length of the longest horn only. In case of a tie, the thickness of the bases will come into play, thereafter the tip – tip measurement, thereafter the date the trophy was hunted and thereafter the owner in alphabetical order obtained with the oldest one first.
