Estimate your bull elk's Boone & Crockett gross and net score. Enter main beam lengths, tine lengths, beam circumferences, and inside spread below.
Enter all measurements in inches (decimals OK, e.g. 52.5). Leave a tine at 0 if the point does not exist or is under 1 inch.
H1 = between burr and G1 · H2 = between G1 and G2 · H3 = between G2 and G3 · H4 = between G3 and G4

Boone and Crockett (B&C) is the gold standard scoring system for North American big game, and elk (Cervus canadensis) are scored differently from whitetail or mule deer. The elk score adds up the inside spread credit, both main beam lengths, all tine lengths on both sides, and four circumference measurements per side. A symmetrical, heavy-beamed 6x6 bull will score dramatically higher than an irregular or light-framed animal with the same number of points.
The inside spread credit is limited to the length of the longer main beam. If your spread is 44 inches but the longer beam is only 52 inches, you get full 44-inch credit. If your spread exceeds the longer beam length, you only count the beam length as spread credit — the excess does not add to gross score.
To count as a scoreable tine under B&C rules, a point must be at least one inch long and must be longer than it is wide at one inch of length. This rule eliminates sticker points and abnormal kicker points from the typical score. Each scoreable point is measured from the tip to where it would intersect the main beam line. Brow tines (G1), bez tines (G2), and trez tines (G3) are the three closest to the base. G4, G5, and G6 extend toward the tips of the beams. Most mature 6x6 bulls will have G1 through G5 and lack a true G6.
Age drives antler development more than genetics in most populations. A rough guide:
The Boone and Crockett minimum for typical American elk is 360 points net, and for non-typical elk it is 385 points net. Very few bulls in the wild ever reach book minimums — they represent the top fraction of a percent of animals harvested. The all-time B&C world record typical elk scored 1,044-⅜ points (note: early records used a different counting system; modern scores for large bulls run in the 400–440 range for the very best). A 380-inch typical gross is a truly exceptional bull by any modern standard, and a 340+ net is a bull most elk hunters would be thrilled to tag in a lifetime of hunting.
The four circumference measurements (H1–H4) per side contribute significantly to total score. A heavy-beamed bull with 9-inch H1 circumferences will add 72 points in circumferences alone across both sides. Mass is one of the key differences between a 300-inch bull and a 370-inch bull with similar tine lengths. When field-judging a live bull, pay attention to beam mass as much as tine length and spread.
The minimum net score for typical American elk entry into Boone and Crockett records is 360 points. For non-typical elk, the minimum is 385 points net. Pope and Young (archery) minimums are lower at 260 for typical and 300 for non-typical. This calculator computes gross and net score but does not distinguish typical vs. non-typical entry — that determination requires an official B&C measurer.
The fundamental B&C method is the same — add main beam, tines, circumferences, and spread, then subtract side-to-side differences for net score. The biggest difference is scale (elk have far more total inches) and the number of measurable tines. Elk are scored G1 through G6 per side, while typical whitetail scoring only goes to G4 or G5. Elk also have four circumference measurements per side versus four for deer, but at much larger values.
Yes. Simply enter 0 for G5 and G6 on each side (and any other missing tines). The calculator treats 0-inch tines as non-existent and will not penalize you for missing points — absent tines simply contribute nothing to gross score. A 5x5 bull just won't have G5 or G6 lengths to add.
A book bull is one that scores high enough for entry into the Boone and Crockett record book — 360 net typical or 385 net non-typical. In practice, hunters often use "book bull" loosely to mean any exceptional trophy-class animal. A gross score of 360+ is often called a "gross book" bull even if deductions drop it below net minimum.
This calculator applies the exact B&C typical scoring formula. The accuracy of your result depends entirely on the accuracy of your measurements. Official B&C scores are taken after a 60-day drying period by a certified measurer with a flexible steel tape following strict panel rules. Field measurements or green scores (taken fresh) may differ by 1–5% from final official scores due to shrinkage during drying.
