Antler scoring follows the Boone & Crockett (B&C) or Pope & Young methodology — the official measurement systems for North American big game trophies.
Tools needed: - 1/4-inch wide flexible steel cable (not cloth tape) - Small steel ruler or calipers for girth measurements - Pencil and scoring sheet
Step 1 — Inside Spread Credit
Measure the greatest inside distance between the main beams, perpendicular to the centerline of the skull.
- This measurement cannot exceed the longer main beam length
- Record to nearest 1/8 inch
Inside spread credit = _____ in
Step 2 — Main Beam Lengths (Both Antlers)
Run the steel cable along the outside of each main beam from the burr (base) to the tip, following the curvature.
Right main beam: _____ in Left main beam: _____ in
Step 3 — Tine (Point) Lengths
Measure each tine from its base (where it branches off the main beam) to the tip.
Tines must be at least 1 inch long to be counted as a separate point.
Step 4 — Mass (Circumference) Measurements
Measure circumference at four locations on each antler:
Step 5 — Calculate Gross Score
Gross Score = Inside spread + Right main beam + Left main beam + All G measurements + All H measurements
Step 6 — Calculate Symmetry Deductions
For each matched pair (right beam vs. left beam, right G1 vs. left G1, etc.), subtract the smaller from the larger. The differences are the deductions.
Net Score = Gross Score − Total Deductions
Scoring Example — 10-Point Buck
Inside Spread: 16.5"
Gross score: 16.5 + 23.5 + 22.0 + all points and mass = approximately 148.5"
Total deductions: (23.5−22.0) + (5.0−4.5) + (10.0−9.5) + (9.0−8.0) + (7.0−6.5) = 1.5+0.5+0.5+1.0+0.5 = 4.0"
Net typical score: 148.5 − 4.0 = 144.5"
Frequently Asked Questions
- What is the minimum score to enter the Boone and Crockett record book?
- B&C record book minimum scores (net, after deductions): Typical whitetail = 160 inches. Non-typical whitetail = 185 inches. Typical mule deer = 190 inches. Non-typical mule deer = 230 inches. Typical elk (Rocky Mountain) = 360 inches. Non-typical elk = 385 inches. These are the 'Awards' minimums for the All-Time Records book. The Pope & Young (archery only) minimums are lower: typical whitetail = 125 inches, non-typical = 155 inches. Less than 5% of harvested white-tailed deer reach B&C minimums.
- How do I score non-typical antler points in Boone and Crockett?
- Non-typical points (abnormal tines — points that grow in unusual directions, forks on tines, or additional points beyond the standard 5 per side) are added to the gross score but are NOT deducted. They also don't have a left/right symmetry partner, so no symmetry deduction is taken against them. Non-typical points are totaled and added to the gross. The entire score then goes into the Non-Typical category if total abnormal point length is substantial. A typical rack with even one significant abnormal point may score higher in the Non-Typical category due to the added gross score without symmetry deductions.
- Why do some deer score higher gross but lower net?
- A large asymmetric deer (very long on one side, shorter on the other) can have an impressive gross score from sheer mass and length but significant net deductions from the symmetry penalty. Example: a 160-inch gross deer with 30 inches of deductions nets only 130 inches and would not make the B&C typical record book. By contrast, a 155-inch gross deer with only 2 inches of deductions nets 153 inches — not qualifying but much closer. This is why hunters and wildlife managers sometimes favor 'symmetric' bucks in genetics conversations — symmetric racks score higher net relative to gross.
- When can I officially score a deer's antlers?
- For official Boone & Crockett or Pope & Young record book entry, antlers must air-dry for a minimum of 60 days before official scoring. Fresh antlers retain moisture that causes them to shrink slightly as they dry — scoring fresh antlers would produce inflated measurements. For your own estimate or informal scores, you can measure immediately. If submitting for record consideration, have an official B&C or P&Y measurer re-score after the 60-day drying period for the definitive official score.
