Montana Unit 331 Elk Hunting Guide
Montana Unit 331 is a substantial elk hunting district spanning nearly 872,000 acres in southwestern Montana, with elevations ranging from roughly 5,000 feet in the lower drainages to over 11,000 feet along the high ridgelines. With 83% public land, this unit offers DIY hunters genuine access to a diverse range of elk country — from sagebrush foothills to timbered slopes and alpine basins. For hunters researching where to invest their Montana elk application, Unit 331 deserves serious consideration, and the data tells a clear story about what to expect.
Unit 331 contains no designated wilderness, which means nonresident hunters can pursue elk here without the guide requirement that applies to Montana's wilderness zones. Road-accessible terrain and a high proportion of public land make this a legitimate DIY destination for both resident and nonresident applicants willing to put in the scouting work. The unit's size — nearly 50 square miles larger than Rhode Island — means hunting pressure is distributed across a large landscape, and hunters who venture off the obvious access corridors can find elk away from the crowds.
This article draws on data compiled by HuntPilot to give hunters a factual foundation for evaluating Unit 331. Whether you're a Montana resident applying for the first time or a nonresident weighing a multi-year point investment, the numbers here will help you make an informed decision.
Harvest Success Rates
Unit 331's harvest data from recent years gives hunters a realistic benchmark for what to expect in the field. In 2024, 3,112 hunters pursued elk in the unit, with 598 animals harvested — a 19% overall success rate. In 2022, 2,782 hunters took to the field and harvested 583 elk, producing a 21% success rate.
A few observations are worth drawing from these numbers:
- Hunter numbers are growing. From 2022 to 2024, total hunters in the unit increased by roughly 330 hunters — a 12% increase in participation over two years.
- Harvest totals held steady. Despite the increase in hunter pressure, the raw harvest numbers were comparable (583 vs. 598), suggesting the elk population can support consistent harvest at these levels.
- Success rate declined modestly. The drop from 21% to 19% likely reflects the increased competition from more hunters rather than a collapse in elk numbers. At a statewide level, 19–21% success is a reasonable and honest expectation for an elk unit of this size and accessibility.
For context: a 19–21% success rate is typical for public-land elk hunting in Montana's general and limited-entry districts. Hunters accustomed to whitetail hunting, where success rates of 50%+ are common, should calibrate expectations accordingly. Elk hunting is demanding, and this unit's numbers reflect honest outcomes — not inflated statistics from a handful of guided hunters on private land.
Trophy Quality
Counties overlapping Unit 331 carry a moderate history of trophy elk records. This is not a unit historically known for producing the kind of exceptional bulls that define Montana's most legendary limited-entry districts, but it does have a legitimate track record of trophy-class elk. Hunters willing to be selective, pass smaller bulls early in the season, and push into higher-elevation or more remote sections of the unit give themselves the best chance at a mature animal.
The terrain's elevation range — topping out above 11,000 feet — means the unit holds high-alpine elk habitat that receives comparatively less pressure. Bulls that survive multiple seasons in rugged, high-country terrain can develop into genuinely impressive animals. That said, hunters entering Unit 331 with expectations of exceptional trophy production on every tag should recalibrate: the unit offers moderate trophy potential consistent with a large, accessible public-land district.
Herd Health & Population Trends
The harvest data itself provides a useful proxy for herd health in the absence of formal wildlife survey figures. The fact that Unit 331 supported nearly identical harvest totals in 2022 and 2024 — despite absorbing 12% more hunters — indicates the elk population is sustaining itself under current hunting pressure. A collapsing herd would typically show declining harvest even as hunter effort increases; Unit 331's consistency is a positive signal.
The unit's elevation range is also meaningful for herd dynamics. Elk in southwestern Montana typically migrate vertically with the seasons, using high alpine habitat during summer and early fall before dropping to lower elevations as winter pressure builds. A unit ranging from 5,000 to 11,000 feet accommodates this full seasonal migration, meaning resident elk populations have room to move within the unit rather than immediately pushing into adjacent districts. This internal migration dynamic benefits hunters who track seasonal movement patterns and adjust their approach accordingly.
Access & Terrain
At 871,590 total acres with 83% in public ownership, Unit 331 is genuinely accessible to DIY hunters. Roughly 723,000 acres are publicly accessible — a figure that puts this unit among the more open elk hunting landscapes in the American West. Hunters are not dependent on landowner permission or access programs to reach functional elk habitat.
The terrain itself rewards physical preparation. The elevation band from 5,000 to over 11,000 feet means hunters can encounter everything from open sagebrush flats at the lower reaches to steep, rocky alpine country near the ridgelines. Early-season hunters working for bugling bulls during the peak rut in mid-September will often find elk pushed into timbered north-facing slopes and upper basins — country that demands fitness and navigation skill.
Importantly, Unit 331 contains zero designated wilderness. This simplifies access for nonresident hunters: there is no guide requirement associated with hunting this unit, and hunters can plan a fully self-guided trip without the logistical and financial overhead of hiring a licensed outfitter. That said, the high-elevation portions of the unit are not casual country. Hunters should come prepared for significant elevation gain, variable weather, and the physical demands of packing out an elk from rough terrain.
The 83% public land figure also means that the 17% private land in the unit can act as refuge for elk that learn to avoid hunting pressure. Hunters who focus exclusively on road-accessible public land may find educated elk on adjacent private ground. Gaining legal access to private inholdings or focusing effort on areas deeper into public land — away from easy vehicle access — tends to improve outcomes.
HuntPilot Analysis: Is Unit 331 Worth Applying For?
For Montana residents, Unit 331 is a strong candidate. The combination of high public land access, no wilderness guide requirements, and consistent 19–21% success rates makes this a unit where a resident hunter can realistically expect to fill a tag with proper preparation. The cost of entry is low (detailed in the next section), and the unit's size means a dedicated hunter has room to find elk away from concentrated pressure.
For nonresidents, the calculus is more nuanced. Unit 331 offers genuine DIY opportunity — 83% public land, no wilderness, and a track record of consistent harvest — but nonresident application fees and tag costs are significantly higher than resident costs. Nonresidents should evaluate whether the unit's moderate trophy potential aligns with their goals. If the objective is a quality elk hunting experience on public land without a guide requirement, Unit 331 is a legitimate option. If the objective is maximizing the chance at a record-class bull, hunters should evaluate whether longer-odds, higher-quality limited-entry districts better match their ambitions.
One notable data point: the B-Tag quota for Unit 331 increased by 100 tags (25%) from 2025 to 2026, moving from 400 to 500 total tags. This expansion in tag availability is a meaningful signal — managers are confident the herd can support increased harvest, and it may modestly improve draw competitiveness for the coming season. Hunters who have been waiting for an accessible entry point into Unit 331 should take note.
The unit is not a guaranteed trophy factory, but it is a legitimate, data-backed elk hunting destination with real access and honest success rates. That combination is harder to find than it sounds.

Unit 331 covers nearly 872,000 acres with elevations spanning from approximately 5,000 feet to over 11,100 feet. The lower reaches feature open sagebrush and grassland terrain, while mid-elevation slopes hold the timbered country that elk favor during hunting season. The upper reaches push into alpine basin and ridgeline terrain above treeline. Hunters should be prepared for significant elevation gain and variable conditions, particularly in high-country areas during the fall season.
What is the harvest success rate in Montana Unit 331?
In 2024, Unit 331 produced a 19% overall success rate across 3,112 hunters, with 598 elk harvested. In 2022, 2,782 hunters achieved a 21% success rate with 583 elk taken. These figures represent the full unit across all hunt types and are consistent with realistic expectations for public-land elk hunting in Montana. Hunters who focus on less pressured terrain and put in genuine scouting time tend to outperform the unit average.
How big are the elk in Montana Unit 331?
Unit 331 overlaps counties with a moderate history of trophy elk production. This is not a unit defined by exceptional trophy output at the level of Montana's most elite limited-entry districts, but it has a legitimate record of producing trophy-class bulls. Hunters targeting mature bulls will improve their odds by focusing on high-elevation, lower-pressure terrain and being willing to pass young bulls early in the season.
Is Montana Unit 331 worth applying for?
For residents, Unit 331 is a strong choice — 83% public land, no wilderness (meaning no guide requirement for nonresidents either), consistent 19–21% success rates, and a 25% increase in B-Tag availability from 2025 to 2026 all make this a unit with genuine appeal. For nonresidents, it's a legitimate DIY option with honest access and realistic harvest data, though hunters prioritizing maximum trophy potential should compare it carefully against more exclusive limited-entry options. The unit is not the easiest draw in Montana, but it offers a well-rounded elk hunting experience backed by real data.
Do nonresidents need a guide to hunt Unit 331?
No. Unit 331 contains no designated wilderness, which means nonresidents are not required to hire a licensed guide or outfitter to hunt here.
