Mule deer reference · Antlers
The forked-and-forked-again rack that no whitetail wears — built and dropped every year, scored in inches, and grown only by bucks that live long enough. The structure, the Western point count, the growth cycle, and how a muley makes the book.
The defining trait
The single fastest way to know mule deer antlers: the main beam bifurcates— splits into two — and each of those branches splits again. That repeated forking builds the symmetrical, branched rack that defines the species, where a whitetail throws single tines up off one unbroken main beam. A “four-point” muley in Western count carries four points per side built from that forking, usually plus a brow tine (eye guard) at the base.
Everything else about the antler — the annual velvet-to-hard cycle, the spring shed, the calcium pulled from the skeleton to grow it — is the same deer biology that drives elk antlers, just at a smaller, forkier scale.
Points + scoring
Western hunters count points per side, typically excluding the eye guard, so the classic mature buck is a “4-point” (a 4x4). Boone & Crockett scores a typical mule deer by adding beam lengths, points, inside spread, and circumferences, then subtracting asymmetry. A typical muley reaches the record book around 190 inches; 150–170 is a solid mature buck and 200-plus is exceptional. Non-typical bucks, carrying extra abnormal points, are scored on their own much higher scale.
Big antlers are mostly a function of age. A buck needs to reach four to six-plus years to grow his best rack, which is why low-pressure, limited-entry units — like GMU 59, where Colorado’s draw-only deer tags keep pressure down — produce the heavy, mature bucks.
Frequently asked
Mule deer antlers grow the same way as elk and other deer — a new set each year from the pedicle on the skull, sheathed in blood-rich velvet through spring and summer, then mineralized into hard bone and stripped of velvet in late summer. The defining mule deer trait is the structure: the main beam forks, and each fork forks again, building the branched, symmetrical 'forky' rack rather than the single-beam-with-tines pattern of a whitetail.
A 4x4 (or 'four-point' in Western count) mule deer has four points on each antler, the classic mature-buck configuration. Western hunters count points per side and usually don't include the brow tine (eye guard) in that number, so a '4-point' muley typically carries eye guards plus the forked-and-forked-again main structure. Eastern count would call the same buck an 8- or 10-pointer by counting every tine on both sides.
Yes. Like all deer, mule deer bucks grow a complete new set of antlers every year and drop them every year, typically shedding from January through March and beginning new growth within weeks. Shed hunting for mule deer antlers is popular in spring as the snow recedes, though many western states regulate it to protect wintering wildlife.
Boone & Crockett scores typical mule deer by adding the main beam lengths, all the points, the inside spread, and circumference measurements, then subtracting left-right asymmetry. A typical mule deer reaches the B&C record book around 190 inches; 200-plus is exceptional. Non-typical mule deer (with extra, abnormal points) are scored on a separate scale where totals run much higher.
A mature mule deer buck commonly scores 150–170 Boone & Crockett inches, with trophy-unit bucks reaching 180–190+ and record-book typicals beyond 190. Antler size depends heavily on age and habitat — bucks need to reach four to six-plus years of age to grow their biggest racks, which is why low-pressure, limited-entry units that let bucks mature produce the largest antlers.
