Scoring a Blacktail Buck
For many of us who chase blacktail deer through Oregon's dense coastal timber or the brushy canyons of the Cascades, the sight of a mature buck is a heart-stopping moment. But beyond the thrill of the hunt, there's a natural curiosity about the size and symmetry of those antlers. Trying to accurately "score" a blacktail buck, whether in the field or after the harvest, can feel like a daunting task, especially with their often unique and sometimes quirky antler configurations. This guide is here to demystify the process, helping you understand the nuances of blacktail antler growth and how to confidently put a number on that hard-earned rack.
The Basics of Blacktail Antler Growth and Terminology
Before we dive into the tape measure, it's crucial to understand what makes a blacktail buck's antlers unique and the language we use to describe them. Blacktails are distinct, and their antlers often reflect the challenging environments they inhabit.
Understanding Blacktail Antler Characteristics
Columbian blacktail deer, found predominantly in Western Oregon, are a different beast than their mule deer cousins or even the Rocky Mountain elk that roam the eastern part of the state. While mule deer are known for their characteristic "forked" antlers, blacktails often display a more complex, sometimes less symmetrical growth pattern. You might encounter bucks with a very strong main beam and multiple points stacking up, or others with more modest but well-formed racks. The "typical" blacktail rack often has fewer main points (G-points) than a mule deer, but can make up for it in mass and unique abnormal points.
Antler development in blacktails is a fascinating interplay of genetics, the buck's age, and the quality of nutrition available in their habitat. A buck in a clearcut rich with browse and minerals will likely grow a larger, healthier rack than one struggling in old-growth timber with scarce food. Older bucks, generally speaking, will have more mature racks, though some can "go downhill" in their very senior years.

Understanding these characteristics is the first step in appreciating the antler you're looking at, regardless of its score.
Essential Scoring Terminology You Need to Know
Scoring deer antlers uses a standardized system, largely based on the Boone and Crockett Club's methodology. While this system is applied to all North American deer, understanding the terms specifically for blacktails helps.
- Main Beams: These are the primary structural components of the antler, extending from the pedicle (the base where it attaches to the skull) upwards and outwards, often curving forward. You'll measure the length of each main beam from its base to its tip.
- Typical Points (G-points): These are the tines that project from the main beam. They are typically measured from the top of the main beam to the tip of the point. They are numbered sequentially: G1 (brow tines), G2 (first point back), G3 (second point back), and so on. A true typical rack aims for symmetry between these points on both sides.
- Abnormal Points: Sometimes called "non-typical" points, these are any projections that don't fit the typical pattern or originate from a typical point. They can appear anywhere on the main beam or points and are usually not symmetrical. For blacktails, these can be quite common and add a lot of character, but they are measured and handled differently in scoring.
- Inside Spread: This is the greatest width between the inside edges of the main beams. It's measured at a right angle to the skull.
- Circumference Measurements (H1, H2, H3, H4): These are four girth measurements taken at specific points along the main beam, typically between the typical points. H1 is usually the measurement between the burr (the rough, bony base of the antler) and the G1. H2 is between G1 and G2, H3 between G2 and G3, and H4 between G3 and the tip of the main beam. These measurements contribute significantly to the overall mass score, which can be a real differentiator for blacktail bucks. The overall density and mass of a blacktail's antlers often impress, even if the tine length isn't as dramatic as a Rocky Mountain mule deer.
The Official Boone and Crockett Scoring Method for Blacktails
The Boone and Crockett (B&C) Club's scoring system is the gold standard for measuring North American big game trophies. While very few blacktail bucks will ever reach the official B&C minimums, the method provides an excellent framework for consistently and accurately assessing any buck's rack.
Step-by-Step Measurement for a Typical Blacktail
Scoring a typical blacktail buck focuses on symmetry and clean, traditional antler growth. Here’s the sequence you’d follow:
- Inside Spread: First, measure the greatest inside spread of the main beams. This is a single measurement, taken at the widest point between the inner edges of the beams. Laying a ruler across the top of the beams at right angles to the skull is the common method.
- Main Beam Length: For each antler, measure the main beam from the center of the burr along the outside curve to the longest tip. This requires a flexible steel tape measure and careful tracing of the curve.
- Typical Point Lengths (G1, G2, G3, G4…): For each point that projects from the main beam, measure its length from the nearest edge of the main beam to its tip. Ensure these are indeed typical points, growing in the standard fashion. If a buck has three typical points on one side and only two on the other, you'll still measure what's present, and the difference contributes to deductions for asymmetry.
- Circumference Measurements (H1, H2, H3, H4): These measurements capture the mass of the antler. For each side, measure the circumference at four specific points:
- H1: Smallest circumference between the burr and the G1 point.
- H2: Smallest circumference between the G1 and G2 points.
- H3: Smallest circumference between the G2 and G3 points.
- H4: Smallest circumference between the G3 point and the tip of the main beam. If a point isn't present, the measurement is taken at the corresponding spot where it would be, or equidistant between the other points.
After taking all these measurements, you add up the lengths for the left side (main beam, G-points, H-measurements) and the right side separately. Then, you subtract any differences between the symmetrical typical points and circumference measurements from the total. This gives you the net typical score. For anyone looking for detailed guidance on how to use a score sheet, online resources from organizations like GoHunt often have downloadable sheets and tutorials that walk you through each step visually, which can be incredibly helpful.
Handling Non-Typical Points and Deductions
Not all blacktail bucks grow perfectly symmetrical, "typical" racks, and that's perfectly okay – in fact, it often adds to their character! This is where non-typical scoring comes in.
- Abnormal Points: Any point that doesn't fit the typical symmetrical pattern (e.g., a sticker point off a G2, a point coming off the back of the main beam, or even a drop tine) is an abnormal point. You measure the length of each abnormal point from where it leaves the main beam or a typical point to its tip. These lengths are then added to a separate "non-typical" column. For a true non-typical score, you'd calculate the gross typical score, then add all the lengths of the abnormal points to it.
- Deductions for Asymmetry: For a typical score, symmetry is paramount. If your buck has a G2 that's 8 inches on one side and 6 inches on the other, the 2-inch difference is a deduction. Similarly, if the H2 circumference on the left is 5 inches and on the right is 4.5 inches, that 0.5-inch difference is deducted. All these differences are summed up and subtracted from the gross score (the combined total of all main beam, typical point, and circumference measurements) to arrive at the net typical score.
It's important to remember that most blacktail bucks you encounter, especially on public land in Oregon, won't necessarily qualify for the Boone and Crockett record book minimums, which are quite high. However, using the B&C method still provides an excellent, objective way to compare bucks year after year, or between hunting buddies. It gives you a consistent language to describe and quantify a buck's antlers.
Practical Tips for Field Scoring and Estimation
While official scoring is done with a tape measure after the hunt, being able to estimate a buck's score in the field can be a real game-changer. It helps you make quick decisions and adds another layer of appreciation for the animal you're pursuing.
Estimating Score on a Live Blacktail Buck
Field judging a blacktail buck is a skill developed over time, combining knowledge of antler growth with hours spent observing deer. It's rarely precise, but you can get surprisingly close.
One common technique is to use the buck's ear length as a rough gauge. An average blacktail ear from base to tip is typically around 6-7 inches. You can use this as a mental ruler to estimate point lengths and beam lengths. If a G2 point looks to be about an ear length, you're looking at roughly 6-7 inches. Similarly, the inside spread of the ears at attention is usually around 14-16 inches. If a buck's main beams extend well outside his ears, you know he's got a decent spread.
Focus on the overall impression of mass and length. Blacktails often appear denser in the beams than mule deer, so pay attention to those circumference measurements. Are the beams thick all the way to the tips, or do they taper quickly? Do you see a lot of "trash" or abnormal points? These add character and non-typical inches, but remember they are deductions for a typical score. Sites like GoHunt often have great photo essays or videos demonstrating how to apply these estimation techniques in real-world scenarios, which can be invaluable training for the eye. The more blacktails you see, both live and harvested, the better you'll become at recognizing what constitutes a good-sized buck in your hunting area. Whether you're waiting for that special buck in the dense timber of the Coast Range or trying to get a quick read in an open clearcut, these estimation skills are incredibly useful.
Tools for Accurate Post-Harvest Measurement
Once you've successfully harvested your blacktail buck, and you're ready for more precise measurements, having the right tools and following a few best practices will ensure accuracy.
First and foremost, you'll need a flexible steel tape measure, preferably one with a narrow width, like a sewing tape measure, to accurately follow the curves of the main beam and points. A fine-tipped pen or pencil is useful for marking starting and ending points, and a small ruler or caliper can help with precise short measurements. An official score sheet, which can often be downloaded from B&C or similar websites, is essential for recording your measurements systematically.
It's often recommended to let the antlers dry for a period, typically 60 days, before taking official measurements. Antlers can shrink slightly as they dry, and measuring too soon might result in a slightly inflated score. While you can certainly rough score them immediately, waiting ensures the most accurate, "dry" measurement. When measuring, always try to be consistent and take your time. Ensure your tape follows the shortest, most direct line for point lengths and the longest, most direct line for beam lengths. Double-check your measurements, and if possible, have a hunting partner or friend verify your readings to eliminate any potential errors. This careful process is what moves you from estimation to a verifiable record for your buck. If you're really serious about having it officially scored, remember that only certified B&C or Pope and Young measurers can do so for the record books, but for personal satisfaction, doing it yourself is a rewarding experience.
| Measurement Type | Description | How to Measure (Simplified) |
|---|---|---|
| Inside Spread | Greatest width between inside edges of main beams. | Lay ruler across antlers, perpendicular to skull, find widest point. |
| Main Beam Length | Length of the main antler shaft from burr to tip. | Use flexible tape, start at center of burr, follow outer curve to tip. |
| Typical Points | Length of tines (G1, G2, etc.) projecting from main beam. | Use flexible tape, measure from nearest edge of main beam to tip of point. |
| Abnormal Points | Length of non-typical tines or projections not following the standard pattern. | Measure from where the point leaves the main beam or typical point to its tip. |
| Circumferences | Girth measurements of the main beam at specific intervals. | Use flexible tape, measure around the beam at H1 (burr-G1), H2 (G1-G2), H3 (G2-G3), and H4 (G3-tip) – or equidistant points if a G-point is missing. Smallest circumference within the segment. |
Scoring a blacktail buck, even if it never makes a record book, is a way to honor the animal and the effort you put into your hunt. It provides a tangible memory and a point of comparison for future adventures in the Oregon wilderness. Knowing the methods and terminology will only enhance your experience out in the field.
