How to score a Coues Deer

I will describe the Boone and Crockett scoring system. The Boone and Crockett scoring system was established in 1932 and since then some modifications and clarifications have been made. The Boone and Crockett system rewards symmetry and mass. There are deductions for lack of symmetry, even in a non-typical Coues Deer. Coues deer are scored the same way as other subpecies of whitetail, but the minimum entry requirements are lower.
For the most part, other recordbooks, such as those for Longhunter Society, Pope and Young, North American Shed Hunters Club, and Safari Club International use the same measuring system which was developed by the Boone and Crockett Club. Safari Club International (SCI) is the only club that does not deduct inches for lack of symmetry and mass. SCI scores are roughly equivalent to a Boone and Crockett score before deductions (otherwise known as the gross score).
There are two categories for Coues Deer in the Boone and Crockett recordbook, typical and non-typical. A typical buck is one that has most of it’s tines coming off the main beam in the standard fashion for this subspecies. For a non-typical buck, there are several tines that come off the beam in abnormal fashion. In general, non-typical points are those that come off the side or bottom of the main beam, are located in an unusual place on the main beam, or branch off from a normal tine. When scored as a non-typical, those abnormal points are added into the score rather than subtracted as they are for a typical score. If a buck has many non-typical points it should be scored as a non-typical. A buck can only be entered into one of the two categories. The final decision on which category the buck is entered in rests with the hunter.
Boone and Crockett has two types of recordbooks. One is the All-time recordbook which records all entries since the system began. The second type is the Awards book which records all entries within the designated three year period that the book covers. There are different minimum scores for entry into the two types of recordbooks (Table 1).

If you would like to look at the Boone and Crockett scoresheets for typical and non-typical Coues deer, please click on the appropriate link below. These files are in PDF format and are courtesy of the Boone and Crockett club. Please visit the Boone and Crockett Club website for more information. The PDF scoresheet files take quite awhile to download (about 2 minutes), so if you have a slower connection, you might want to just look at the excel spreadsheets for an idea of how things are calculated.

I also have some Excel spreadsheets that you can download if you would like. These are simple spreadsheets in which you enter your measurements and it will calculate the score of the buck. Feel free to save these spreadsheets on your computer for your personal use. I have saved them in an older version of Excel (ver. 5.0) so that most people will be able to load these.
How to score
The score of a buck is the sum total of several measurements taken on his antlers. Those measurements include the length of each main beam, the length of each tine, the circumference measurements along the main beam at four specific locations, and the greatest inside spread. All measurements are taken to the nearest 1/8 of an inch.
In order to take those measurements you need some equipment. For most measurements you want to use a 1/4 inch wide, flexible steel measuring tape with graduations in sixteenths of an inch. I find it is also very handy to use a flexible steel cable and an alligator clip to take measurements. For the inside spread, a carpenter’s ruler, which has the extendable section on it is best. I also find it helpful to use masking tape on the antler so that my marks are removable and they are easy to see for measuring.
The photos below show the basic equipment and techniques used for measuring the antlers of a Coues White-tailed Deer.
Let’s use the following buck to demonstrate some of the measurements. This buck has several features that make it excellent for demonstration.
The main beams are measured from the bottom and center of the outside edge of the burr to the tip of the main beam, following the middle of the outside of the beam. See photo below. The measurement is taken for both beams. To establish the center of the base of the beam (the burr), try to line up the antlers when viewing them from the side. Then look for the center of the outside of the burr. Do not start the measurement at the lowest leading edge of the burr or the lowest rear edge of the burr. It must be the center of the outside edge.
This photo shows using a flexible cable to measure the main beam. Note that the cable is to stay in the center of the outside of the beam. The angle of this photo makes it look like the base of the cable isn’t in the center of the beam by the burr, but it is. To determine the center try and line up the antlers when viewed from the side.
Tine lengths are very important measurements and can be somewhat difficult. The critical part is marking the baseline correctly. The baseline of the tine is where it meets the main beam. But generally the tine spreads out at the base and so you want to make sure you are really marking the baseline, not just the swelling where the tine meets the main beam. Many people who are not certified measurers will make this mistake, which results in shorter tine measurements. All tines are measured on the rack as long as they meet the definition of a legal point. In general, that definition is that they must be at least 1 inch long and longer than they are wide.
Marking the baseline. See how the tine swells as it nears the main beam? To make the proper mark, the baseline should be below the noticeable swelling of the main beam created by the “influence” of the tine. This may be easier to see in the lower photo. Many people would incorrectly mark the baseline higher than is show here, resulting in shorter tine lengths. Note also the use of masking tape in the upper photo to make it easier to see your mark and to make the marks removable. If you don’t have masking tape, you can use a pencil to make your marks.
The baseline should be drawn so that it follows the natural curve of the beam. The photo on the left demonstrates how the baseline follows the curve. See how the curve in the cable is the same as the curve in the bottom of the main beam. The photo on the right demonstrates the incorrect way to draw a baseline. In that photo, the cable is pulled straight and is not following the curve of the main beam.
After drawing the baseline, you must determine the center of where the point meets the baseline. You can do this by using your fingers to mark the edges of the tine as it comes into the main beam. Then put a mark on the baseline to indicate the center (that mark is not shown in this photo, but would be made at the center point of the tine where it meets that blue baseline).
Points are measured from the center of the tine where it intersects the main beam to the tip of the point (or from the tip to the baseline). Here I use a flexible steel cable and an alligator clip to get the length. Then the cable is stretched against a measuring tape to get the measurement.
Abnormal points? This buck does indeed have an abnormal point. Look at the photo of Jeff holding his buck. On the buck’s right antler, look at the third tine. There is a point branching off it. That makes it a non-typical or abnormal point. But which point is the normal one and which is the branch? In order to determine that, you have to decide where the baselines are for each point. If both tines came off the main beams, but shared some antler material, they would be a special case called “common base points”. However, in this case, one point branches off the other and does not arise from the main beam. If you take a look at the photo of Jeff holding his buck again, you can see that the tine that arcs back toward the second tine is the one that branches off the normal third tine. Abnormal points are measured very similarly to normal points. The difference is that the baseline of the point may not be on the main beam. In this case the baseline is drawn where the abnormal point intersects the normal 3rd tine. The measurements for abnormal points are placed a special section in the upper right-hand side of the scoresheet. The total of all abnormal points is added into a non-typical score, but subtracted from a typical buck.
Legal points? On Jeff’s buck, notice the small point coming off the top of the main beam near the end of the left beam. Is is a legal point? In order to be a legal, measurable point, it must be at least an inch long and wider than it is long. In this case, that point does not meet the definition of a legal point and therefore is not measured.
For Coues deer, as with other whitetail, there are four circumference measurements on each main beam, regardless of how many tines the buck has. This is another area where novice measurers make a mistake. They may only take 3 circumference measurements on a 4 point buck. The four circumference measurements are taken in the following locations. The first is taken at the smallest place between the burr and the first point. The second is at the smallest place between the first and second points. The third is taken at the smallest place between the second and third points. And the fourth is taken between at the smallest place between the third and fourth points. However, in Coues deer, the fourth “point” is generally the tip of the main beam. In that case, the measurement is taken 1/2 way between the third point and the end of the main beam, as shown below. If the buck has no third point, then the 3rd and 4th circumferences are exactly the same and are taken 1/2 way between the second point and the end of the main beam.
Photo showing proper placement of the fourth circumference measurement on a Coues deer if the buck does not have a fourth tine. It is taken at the 1/2 way point between the third point and the end of the main beam because Coues deer rarely have a fourth tine. If the buck does have a fourth tine then the measurement would be taken at the smallest place between the third and fourth points.
The inside spread measurement is the taken at a right angle to the centerline of the skull at the widest point. Using a carpenter’s rule makes this measurement easier to take. The ruler should be touching the center of the main beams on each side, unless one antler is significantly higher than the other.
Use of a carpenter’s rule to measure the greatest inside spread. You can see the extendible brass section of the ruler on the left hand side of the photo. Note that the measurement is taken at a right angle to the centerline of the skull. In this photo, the differing lengths of the main beams makes it look the measurement is skewed, but note the position of the ruler in relation to the skull plate.
Tip-to-tip and Greatest Outside Spread
There are other measurements that go onto the B&C scoresheet, but they do not influence the score of the animal. They are used to help distinguish one rack from another.
The tip-to-tip spread is simply taken by stretching the tape between the center of each tip of the end of the main beam. This does not have to be at a right angle to anything. So if one beam is higher than the other, it makes no difference.
The greatest outside spread is one that is generally taken by laying the rack down at a right angle to a wall and marking the widest point, whether the that is the main beam or a point.
Here I am taking the greatest outside spread measurement. The ruler on the left helps locate the proper outside edge. Note that in this case, the greatest outside spread is widest where the third points bow out. To take this measurement, I would mark where the straightedge is hitting the concrete and then measure the distance to the wall, making sure it is at a right angle to the wall. You can use the special type of ruler shown here to determine the right angle.
