Complete Antler Scoring Worksheet

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.

PointRightLeft
G1 (brow tine)______
G2 (second point)______
G3 (third point)______
G4 (fourth point)______
G5 (fifth, if present)______

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:

LocationRightLeft
H1: between burr and G1______
H2: between G2 and G3______
H3: between G3 and G4______
H4: between G4 and G5 (or midpoint)______

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

MeasurementRightLeft
Main beam23.5"22.0"
G15.0"4.5"
G210.0"9.5"
G39.0"8.0"
G47.0"6.5"
H14.5"4.5"
H24.0"4.0"
H33.5"3.5"
H43.0"3.0"

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.
