Created in 1949 by six elite members of the Boone & Crockett Club, the original B&C scoring system is essentially the same popular method used today. The Pope and Young Club also uses this system for trophies taken with archery gear. Here's how you measure a white-tailed buck and get an official B&C score:
Keep the following general rules in mind when measuring and scoring a white-tailed deer using the B&C method:
• Take all measurements with a flexible steel cable or 1/4-inch flexible steel tape.
• Enter fractional figures to the nearest eighth or one-sixteenth.
• Be sure to keep the measuring tape or cable tight and centered against the beam or point. Any slack will skew the final score.
Measurements That Matter
1. Document the length of both main beams.
• Start from the center of the lowest outside edge of the burr on the outer side of the main beam.
• Run a flexible steel cable along the center of the outer side of the main beam all the way to the most distant point of it. At the tip, mark the cable (you might use an alligator clip) to identify the end of the main beam. Use the 1/4-inch steel tape to determine the length of the marked cable.
• Use the help of a partner or masking tape to ensure cable follows the centerline of the antler.
2. Jot down the length of all the normal main points.
• Line up the steel measuring tape along the outer, top edge of the main beam under each main point. Mark this baseline with a pencil. This line represents what the main beam would look like if the point was not present and is your starting point for measuring your points.
• Start at pencil baseline and measure the center of the outer side of each point all the way to the most distant point of it. A partner or masking tape will help during this step.
3. Document four circumference measurements of the main beam. All antler racks have only four circumference measurements, regardless of the number of points per main beam.
• Start at the smallest point between the burr and the first point and repeat the measurements between all main points until you have recorded four circumference measurements.
• If brow point (G1) is missing, take first and second main beam circumference measurements at smallest place between burr and first main point.
• In the case of an 8-point whitetail, the fourth point (G4) is not present. Take the measurement halfway between the third point and the tip of the main beam.
4. Determine the Spread Credit.
• Spread Credit is the larger measurement from either the inside spread (the widest point between the main beams) or the longest main beam.
5. Tally and record the sum of the total of lengths of all the abnormal points.
• Abnormal points are non-typical in their location. Examples include smaller points that grew from the bottom or sides of the main beam or main point, or “extra” points that exist beyond the normal pattern of points.
6. Keep track of difference of each adjacent measurement between the right and left antler.
• Measure the “bigger” antler first. Then, determine the difference of the same measurements for the adjacent “smaller” antler. Do this for the main beams, main points and circumference measurements.
The Scoring Formula
Now, you have all your measurement data. Add it all up and subtract deductions.
For typical whitetail antlers, follow this formula:
+ Total length of both main beams
+ Total length of all the points
+ Total length of four circumference measurements
+ Spread Credit
- Total of lengths of all abnormal points (See *NOTE)
- Total difference between each measurement of the right and left main beams
- Total difference between each measurement of the right and left main points
- Total difference between each of the four circumference measurements
= Final Score
*NOTE: For a non-typical trophy you add abnormal points (Step 5) instead subtracting.

Hey, That Doesn't Count
Some information recorded on the B&C score sheet is purely supplemental data that's used by officials and record books to keep an accurate history of the animal taken. In fact, these three measurements required on the B&C score sheet are not added into final score:
• The number of points on each antler.
• Tip-to-Tip Spread (distance between the two tips of the main beams).
• Greatest Spread (The distance between the farthest outside portion of each antler).
What's With All The Gs?
The reason antler points (tines) are called G-points is because of line in which they are scored using the B&C system. According to the scoring sheet, antler points are documented on Line G. So over the years, hunters have commonly referred to them as G-points.

Make It Official
Official measurements cannot be taken until antlers air dry at room temperature for 60 days. Any score calculated before the drying period is known as the “green score.” For an official score, antler trophies need be measured and scored by a trained and certified B&C measurer.
