As a lifelong hunter and outdoor writer, I’ve spent countless hours in the field observing and learning about whitetail deer, mule deer, and pronghorn antelope. One question I consistently encounter, from seasoned hunters to newcomers, revolves around understanding size – what does a 90 inch buck really mean? How old is a 7 point buck? What’s the significance of an 18 point deer or a 140 inch 8 point buck? This guide will break down the complexities of deer and antelope scoring, age estimation, and what different measurements tell us about these magnificent animals. We’ll cover everything from typical whitetail characteristics to understanding a massive 220 inch whitetail, and even touch on 90 inch antelope measurements.
Before diving into specific sizes, it’s crucial to understand how antlers are scored. The most widely recognized system is the Boone and Crockett Club (B&C) scoring system. This system measures antler length and circumference at various points, adding these measurements together to arrive at a final score. Different states may also have their own scoring systems, but B&C remains the gold standard. For pronghorn, a similar system is used, though scores are generally lower than those for deer. A 90 inch antelope is considered a respectable size, though mature bucks can exceed 80-90 inches.
While both whitetail and mule deer are scored using the B&C system, there are key differences. Whitetail antlers tend to have more points and a wider spread, while mule deer antlers are typically more symmetrical and have a narrower spread. This impacts how scores are achieved. A 140 inch 9 point whitetail is a very good deer, while a 140 inch mule deer might have fewer points but greater overall mass. You can find detailed scoring instructions on the Boone and Crockett Club website: https://www.boone-crockettclub.org/
Antlers are categorized as “typical” or “non-typical” based on the symmetry of the main beam. A typical rack has a main beam that curves symmetrically, with points growing upward from it. Non-typical racks have abnormal points or deviations from this symmetry. Non-typical antlers are often scored differently, with deductions made for irregularities. An 18 point buck is often, but not always, a non-typical deer, and scoring can be more complex.
Antler size is strongly correlated with age, but it’s not a perfect indicator. A 7 point buck is typically a young deer, often 2.5 to 3.5 years old, but can vary depending on genetics, nutrition, and habitat. As deer mature, their antlers generally grow larger and more complex. However, a deer’s peak antler development usually occurs between 4.5 and 6.5 years old. After that, antler size may plateau or even decline. According to the National Park Service, factors like food availability and overall health play a significant role in antler growth. https://www.nps.gov/subjects/wildlife/deer.htm
While not foolproof, antler points can provide a rough estimate of age. Here’s a general guideline:
Remember, these are just averages. Some deer may develop more points earlier in life, while others may take longer. The USDA Forest Service offers resources on deer management and habitat, which can influence antler development. https://www.fs.usda.gov/working-with-us/wildlife-conservation
Don’t rely solely on antler points to estimate age. Consider the deer’s overall body size, muscle condition, and the color of its coat. Mature bucks typically have thicker necks and more muscular builds. A healthy deer will also have a glossy coat. These factors, combined with antler point count, provide a more accurate assessment.
So, what does a specific score actually signify? Here’s a breakdown for whitetail deer:
| Score Range | Description | Typicality |
|---|---|---|
| 80-100 inches | Average buck | Common |
| 100-120 inches | Good buck | Common |
| 120-140 inches | Very good buck | Increasingly rare |
| 140-160 inches | Mature, impressive buck | Rare |
| 160-180 inches | Boone and Crockett caliber buck | Very rare |
| 180+ inches | Exceptional, trophy buck | Extremely rare |
A 140 inch 8 point buck is a significant trophy in many areas, representing a mature and healthy animal. Reaching a 220 inch whitetail is the dream of many hunters – these are truly exceptional animals. Remember that scoring is just one way to appreciate a deer; ethical hunting and respect for the animal should always be paramount.
Several factors contribute to antler size beyond age and genetics:
