5 Secrets Behind The World’s Most Monstrous Non-Typical Mule Deer Racks

The non-typical mule deer stands as one of North America’s most sought-after and mysterious big game trophies. As of late 2025, hunters and wildlife biologists continue to be fascinated by the rare bucks whose antlers defy the symmetrical, forked-horn standard, instead erupting into a chaotic, awe-inspiring crown of bone.

The term "non-typical" is not just a casual description; it is a formal scoring classification used by organizations like the Boone and Crockett Club (B&C) to recognize mule deer with extraordinary, asymmetrical antler growth. These majestic animals are the result of a perfect, or perhaps imperfect, storm of genetics, age, and environment, creating a truly unique spectacle in the wild.

The Titans of the Tines: A List of Record Non-Typical Mule Deer

To understand the sheer magnitude of a non-typical rack, one must look at the record books. The following list details some of the most famous and highest-scoring non-typical mule deer in hunting history, providing the essential entities and scores that define this category.

  • The Ed Broder Buck (World Record)
    • Score: 355 2/8 inches (Boone and Crockett Net Score)
    • Location: Alberta, Canada
    • Hunter: Ed Broder
    • Date: 1926
    • Significance: This is the undisputed B&C World Record for a non-typical mule deer. Its score is a benchmark that has stood for nearly a century, regarded as one of North America's greatest trophy heads.
  • The Gordon Buck (Archery Legend)
    • Score: 338 7/8 inches (Gross Score)
    • Hunter: Justin Gordon
    • Date: 2018
    • Significance: While not the B&C World Record, this deer is recognized as the largest non-typical mule deer ever taken by a bowhunter, highlighting the pinnacle of archery achievement.
  • The Dennis Bennett Buck (Pope & Young World Record)
    • Score: 291 1/8 inches (Pope and Young Net Score)
    • Location: Arm River, Saskatchewan, Canada
    • Hunter: Dennis Bennett
    • Date: October 1, 2018
    • Significance: This buck holds the Pope and Young Club’s World Record for the largest non-typical mule deer taken with a bow and arrow, confirmed in 2019.
  • New Mexico State Record
    • Score: 306 2/8 inches
    • Location: Rio Arriba County, New Mexico
    • Hunter: Joseph A. Garcia
    • Significance: A monumental buck that illustrates the potential for world-class non-typical growth in the Southwestern United States.

The Anatomy of Atypical Antler Growth

What exactly makes a mule deer rack "non-typical"? A typical mule deer, by definition, possesses a symmetrical rack with four main points (tines) on each side, plus eye guards (brow tines). The defining characteristic of the species is the "forked" pattern, where the main beam splits into two equal forks, and each of those splits again. A non-typical deer deviates dramatically from this pattern.

The Boone and Crockett Club's scoring system is meticulous in measuring this deviation. The minimum entry score for a non-typical mule deer into the B&C All-Time Records is a staggering 210 inches. The final net score is calculated by taking the gross score (the total of all measurements) and subtracting any asymmetrical differences, plus any "non-typical" points that are not part of the basic typical frame. Non-typical points are extra tines that grow in unusual directions, such as drop tines, stickers, or points growing off the main beam or other tines.

The sheer number of scorable points on a non-typical rack can be astonishing. The Ed Broder buck, for instance, features a massive number of points that contribute to its colossal score, with its unique palmation and irregular tines being key factors. Non-typical racks often feature palmation (a flattened, web-like section of antler), extra main beams, or clusters of points growing from a single spot, making each one a unique biological masterpiece.

5 Key Factors That Create a Non-Typical Mule Deer

The formation of a world-class non-typical rack is a complex biological event that requires a convergence of several critical elements. It’s a delicate balance of nature and nurture, where a slight deviation can lead to a spectacular outcome.

1. The Genetic Blueprint (Heredity)

Genetics is the most fundamental factor. Both the mother and the father contribute equally to a buck's genetic potential, and antler characteristics are highly hereditary. Some bucks are simply predisposed to grow non-typical racks. This genetic trait often manifests as abnormal branching that appears symmetrically on both antlers, suggesting a pre-programmed deviation from the typical growth pattern. If non-typical bucks are common in a specific geographic area, it is a strong indicator of a localized genetic influence.

2. Age and Maturity

For a mule deer to reach its full non-typical potential, it must survive to an old age. Antler size and complexity generally increase with age, peaking around five to seven years old. While a young buck may show non-typical traits, it takes several seasons of growth—and survival through multiple hunting seasons—for the rack to develop the mass, length, and sheer number of points required to achieve a record score. Older bucks have the physiological capacity to allocate maximum resources to antler growth, translating into larger, heavier, and often more irregular racks.

3. Nutrition and Habitat Quality

Even with superior genetics, a buck cannot grow a massive rack without a high-quality food source. Adequate nutrition, including essential minerals like calcium and phosphorus, is crucial for bone development. Bucks living in ranges with abundant forage, especially during the spring and summer antler-growing season, have the best chance of maximizing their genetic potential. Areas like Alberta and New Mexico, known for producing massive bucks, typically offer the necessary combination of age structure and rich habitat.

4. Injury to the Pedicle or Body

While genetics cause symmetrical non-typical growth, a physical injury is a major cause of *asymmetrical* or unilateral non-typical antlers. An injury to the pedicle (the bony base on the skull from which the antler grows) can permanently disrupt the growth pattern, causing the resulting antler to be deformed or grow in an atypical manner. Furthermore, a severe injury to the deer's body or leg can sometimes cause the opposite side antler to grow non-typically in the following year, a phenomenon known as "contralateral effect."

5. Hormonal Fluctuations and Disease

Hormonal balance, specifically testosterone levels, dictates the antler cycle. Any disruption, whether due to disease, castration (known as a "cactus buck"), or severe stress, can lead to abnormal or non-typical growth. A buck that retains its velvet late into the season or never sheds it may develop a unique, club-like non-typical rack due to a lack of testosterone. These hormonal anomalies, while rare, can result in some of the most bizarre and highly non-typical racks ever recorded.

The Thrill of the 2024/2025 Non-Typical Hunting Season

The pursuit of the non-typical mule deer remains a central focus for trophy hunters across the Western United States and Canada. The 2024 and 2025 hunting seasons have continued to produce stories of giant, elusive bucks. For example, reports from the 2024 Utah Limited Entry (LE) hunts mentioned hunters pursuing a "great non-typical," showcasing the ongoing, intense effort to locate and harvest these rare animals. Another notable mention was a massive Colorado buck taken in September 2024, which survived an 800-yard tumble down a slope after the shot, miraculously keeping its massive antlers intact.

The sheer unpredictability of a non-typical buck’s rack is what adds to the mystique. Unlike a typical buck where a hunter can estimate a score based on symmetry, a non-typical requires a more complex field-judging process, where every sticker, drop tine, and irregular point adds to the gross score. The challenge is immense, the reward is unmatched, and the legacy of the non-typical mule deer continues to capture the imagination of the hunting world.
