The antlers of a typical whitetail buck deer is scored by using the formula total gross BC score = antler score x 2 + inside spread, where antler score is calculated by using the formula antler score = beam length + total tine length + 4 total circumferences measurements. These equations, which were formulated by whitetail biologist David Morris, are loosely based on the Boone and Crockett Scoring system. The results only provide an estimate of a deer's actual gross BC field score.
The whitetail deer is one of the most pursued game by hunting enthusiasts. Harvested whitetail deer antlers that are displayed as trophy animals are typically given Boone & Crockett (BC) field scores. Hunters often receive recognition or awards for obtaining a particular BC field score. For a typical whitetail deer, the minimum entry score to be included in the Awards book and "Records of North American Big Game" is 170.
To get a quick estimate of the field score of a deer's antlers, the beam length, mass measurements, tine length and inside spread should be measured. A 150 class deer is estimated to have an average of 24 inches plus main beam and average 16 inches per side of mass measurements. The tine length refers to the distance from the tine's tip to the main beam. Tines that measure at least one inch is added to the gross field score. The inside spread is the widest point between the two main beams.
