Montana Unit 110 Mule Deer Hunting Guide

Montana Unit 110 (HD 110) is a general-season mule deer unit covering 507,954 acres in eastern Montana, with 85% of that ground in public ownership. For hunters sorting through options in this part of the state, HD 110 stands out for its sheer size, its high percentage of accessible public land, and a straightforward hunt structure that doesn't require navigating a complicated draw just to chase a buck. This article breaks down what the data actually shows about harvest, access, and trophy potential in this unit, based on figures compiled by HuntPilot.

Elevation in the unit ranges from 2,994 to 8,050 feet, which is a wide spread for this region and suggests hunters will find everything from low prairie breaks and river bottoms to higher benches and ridgelines within the unit boundary. There is no designated wilderness in HD 110, which keeps access relatively simple — no mandatory outfitter requirements and no wilderness permitting to navigate, regardless of residency.

Hunt Structure: General Season for Bucks, Draw for Antlerless

This is the single most important thing to understand about HD 110 before doing anything else: antlered mule deer here are taken on the general season, not through a limited draw. Hunters do not need to win a lottery to pursue a buck in this unit — a general license covers that opportunity.

The draw system in HD 110 applies only to antlerless tags (cow/calf-equivalent doe tags for deer). The B-Tag 00 allocation has moved from 25 tags in both 2024 and 2025 up to 100 tags in 2026 — a 300% increase in quota for that antlerless draw. That's a meaningful jump in doe-tag availability, and it signals that managers are looking to pull more antlerless deer off this unit's population going forward. But it's critical not to confuse that number with buck opportunity — the antlerless quota has zero bearing on a hunter's ability to pursue an antlered deer here, since that's handled on general season and isn't quota-limited in the same way.

Any hunter specifically targeting antlerless deer (for management reasons, meat, or because they already have a buck objective elsewhere in the state) should treat the antlerless draw as a separate, additional opportunity layered onto the general buck season available in this unit.

Harvest Success Rates

HD 110 has posted modest, consistent harvest numbers over the two most recent data years available. In 2023, 2,720 hunters pursued deer in the unit and harvested 385 animals, a 14% success rate. In 2021, 2,236 hunters harvested 323 deer, also a 14% success rate. These figures represent unit-wide totals across all license types and sexes, not a buck-specific breakdown.

The consistency here is notable — two years with matching 14% success rates despite a meaningful increase in hunter numbers (2,236 to 2,720, roughly a 22% jump) suggests a stable deer population that's absorbing additional hunting pressure without success rates collapsing. That's a reasonably good sign for a general-season unit of this size. A 14% success rate is not exceptional by Western big-game standards, but it's in line with what hunters should expect from a large, mixed-terrain general unit where effort, scouting, and willingness to cover ground matter more than simply having a tag in pocket.

Hunters should treat that 14% figure as a blended average across the entire hunter pool — those targeting antlerless deer during the draw hunt, general-season buck hunters, and hunters of varying experience levels and effort are all baked into that number. Individual success is likely to vary significantly based on access strategy and time invested.

Trophy Quality

The counties overlapping Unit 110 carry a strong history of trophy-class mule deer production in the record books. That's an encouraging signal for hunters specifically chasing a wall-worthy buck rather than just filling a tag, but it comes with an important caveat: record-book entries are logged by county, not by hunt unit, so that trophy pedigree is shared across HD 110 and any neighboring units that fall within the same counties. A buck entered in the record books from this general area could have been taken anywhere within that broader county footprint, not necessarily inside HD 110's specific boundary.

That said, a documented, strong trophy history in the surrounding counties is a meaningfully positive data point. It tells hunters that genetics, habitat, and age structure in this part of Montana have historically been capable of producing mature, record-class bucks — not just high volumes of young or average deer. Hunters serious about trophy potential in HD 110 should treat this as a strong starting indicator, while recognizing that finding one of those caliber bucks still requires locating the right habitat, avoiding pressure, and often hunting later in the season when mature bucks become more visible and concentrated.

Access & Terrain

With 85% public land across 507,954 acres, HD 110 is about as DIY-friendly as a general mule deer unit gets in Montana. The overwhelming majority of this unit's ground is open to public hunters, which removes one of the biggest obstacles hunters face in other parts of the state where private ranch lands dominate and public access requires either a draw-in landowner program or outright leasing.

The elevation range — 2,994 to 8,050 feet — points to genuinely varied terrain within the unit. Hunters can expect lower-elevation river breaks, badlands-style terrain, and open prairie country mixing with higher benches and potentially timbered or rougher ground at the upper end of that range. That kind of vertical diversity typically means mule deer distribute differently depending on the time of year and weather — lower elevations and brushy draws holding deer early, with animals pushing to higher or more broken country as pressure and temperature shift through the season.

There is no wilderness designation in this unit (0%), which means no special access restrictions, no outfitter requirements tied to wilderness law, and generally easier logistics for hunters planning a self-guided trip. Vehicle access via public roads should be more straightforward here than in wilderness-heavy units elsewhere in the state, though hunters should always verify current road and access conditions before a trip, since specific route conditions can change season to season.

Hunters planning to scout HD 110 ahead of a hunt should lean on mapping tools that overlay public land boundaries with terrain and elevation data — HuntPilot's map tools, including public land overlays, are built for exactly this kind of pre-season planning, letting hunters identify public access points and terrain transition zones without guessing from old forum posts or outdated information.

HuntPilot Analysis: Is Unit 110 Worth Applying For?

HD 110 earns a solid recommendation for a specific type of hunter: someone who wants a general-season mule deer hunt with real public access, doesn't need to win a competitive draw to chase a buck, and is willing to put in scouting and boot-time across a genuinely large unit to find a mature deer.

The case for this unit rests on three data points working together. First, 85% public land across more than half a million acres means access isn't the bottleneck it is in many Montana units — hunters aren't locked out of most of the landscape by private ownership. Second, the general-season structure for antlered deer means there's no draw gamble standing between a hunter and the opportunity to hunt — this is an every-year option, not a once-in-a-decade draw unit. Third, the surrounding counties' strong trophy history suggests the habitat here is capable of growing genuinely good bucks, not just numbers.

The case for caution: a 14% success rate, while consistent, means the majority of hunters in this unit do not fill a tag. This isn't a unit where success is handed out — it rewards hunters who scout hard, hunt smart, and are willing to work the varied terrain rather than expecting deer to come easy on a huge, mostly open landscape. The rising hunter numbers (2,236 to 2,720 between 2021 and 2023) also suggest this unit's general-season accessibility is becoming more well-known, which could mean more competition for the best pockets of public ground over time.

For a hunter weighing whether to prioritize HD 110 over a comparable general unit, the public land percentage and general-season buck structure make it a strong candidate — particularly for nonresidents who don't want their entire trip contingent on drawing a competitive tag.

How to Apply

Because HD 110 offers general-season opportunity for antlered mule deer, residents and nonresidents alike can access that opportunity through Montana's general deer license structure rather than through a competitive draw — no points, no waiting, no uncertainty tied to buck hunting specifically in this unit.

The antlerless-only draw tags (B-Tag 00) do require application through Montana's limited-quota draw system. Montana's draw for antlerless licenses typically separates resident and nonresident applicant pools, and nonresidents should expect more competitive odds than residents on any limited-quota tag, including antlerless allocations, given the overall nonresident demand for Montana hunting opportunity.

Nonresidents pursuing a general buck tag in HD 110 will still need to secure Montana's nonresident general deer license, which comes with its own statewide availability considerations separate from unit-specific draws. Hunters should check current license structures carefully, since Montana's nonresident license framework has changed in recent years and availability can be capped statewide even when a specific unit like HD 110 doesn't require a unit-specific draw for bucks.

Application dates, fees, and current quota numbers change every cycle. For the most current deadlines, license costs, and draw odds for HD 110's antlerless tags, see HuntPilot's Montana state page at /states/mt.

Frequently Asked Questions

Is Unit 110 a draw unit for mule deer bucks? No. Antlered mule deer in HD 110 are hunted under Montana's general season, meaning a general license — not a competitive draw — covers buck opportunity. The only draw-based tags in this unit are antlerless (doe) tags under the B-Tag 00 quota, which increased from 25 tags in 2025 to 100 tags in 2026.

What is harvest success like in Unit 110? Recent data shows a 14% success rate in both 2023 (385 harvested out of 2,720 hunters) and 2021 (323 harvested out of 2,236 hunters). That consistency across years with rising hunter pressure suggests a stable deer population, though the majority of hunters in any given year do not fill a tag.

How big are the mule deer in HD 110? The counties overlapping this unit carry a strong history of trophy-class mule deer entries in the record books, which is a positive indicator for trophy potential. However, because record-book entries are attributed by county rather than by specific hunt unit, that trophy history is shared with neighboring units in the same counties and isn't an exact measure of what HD 110 alone has produced.

What is the terrain like in Unit 110? The unit spans a wide elevation range from 2,994 to 8,050 feet across 507,954 total acres, suggesting a mix of lower prairie and river-break terrain alongside higher benches and ridgelines. There's no wilderness designation in the unit, which generally simplifies access and logistics for self-guided hunters.

Is Unit 110 worth applying for? For hunters wanting general-season mule deer opportunity with strong public access, HD 110 is a solid option. With 85% public land, no competitive draw required for buck opportunity, and a county-level trophy history that supports genuine trophy potential, it checks several important boxes — though hunters should expect to work for that 14% success rate rather than expect an easy fill.
