Wyoming Unit 21 Pronghorn Antelope Hunting Guide
Wyoming Unit 21 is a substantial pronghorn antelope hunting destination spanning over 400,000 acres across an elevation range of 4,586 to 8,562 feet. With 54% public land and zero designated wilderness, this unit offers genuine DIY accessibility for both resident and nonresident hunters willing to put in the legwork. The terrain diversity — from lower sagebrush flats to higher elevation transition zones — creates the kind of habitat variety that sustains healthy pronghorn populations year after year.
The unit's harvest data tells a consistent story: this is a unit where hunters who draw tags have a realistic shot at filling them. Over a four-year window from 2022 through 2025, success rates have ranged from 55% to 72%, with hundreds of hunters participating each season. That level of consistent production, combined with a solid buck-to-doe ratio from survey data, makes Unit 21 worth serious attention from anyone building an antelope strategy in Wyoming.
For hunters using HuntPilot to research Wyoming pronghorn options, Unit 21 represents a well-documented, data-rich unit with enough public access and historical production to merit a close look. What follows is a detailed breakdown of what the numbers actually say — and what they mean for your application strategy.
Harvest Success Rates
Unit 21's harvest history across the most recent four seasons reveals a unit with strong but variable production:
- 2022: 429 hunters, 294 harvested — 69% success
- 2023: 394 hunters, 282 harvested — 72% success
- 2024: 406 hunters, 270 harvested — 67% success
- 2025: 387 hunters, 213 harvested — 55% success
The trend line is worth acknowledging honestly. Success rates have declined from a peak of 72% in 2023 to 55% in 2025 — a meaningful drop. At the same time, hunter numbers have also declined slightly over the same window, from 429 in 2022 to 387 in 2025. Whether the 2025 dip reflects a single-year weather or population anomaly, tighter draw allocations, or the beginning of a longer decline is worth monitoring in future survey data.
Even at 55%, Unit 21 outperforms many Wyoming units. A coin-flip plus odds of filling a tag — across nearly 400 hunters — is not a unit in crisis. But hunters expecting the 70%-range success that defined 2022 and 2023 should calibrate expectations against the most recent season's data.
Trophy Quality
The counties overlapping Wyoming Unit 21 carry an extensive trophy history in the record books. This is not a unit with marginal or spotty trophy pedigree — the surrounding landscape has been producing record-class pronghorn consistently over multiple decades. That said, a critical caveat applies: trophy records are logged by county, not by hunt unit. Every neighboring unit sharing those counties pulls from the same record pool, so that history is distributed across a broader geography rather than belonging exclusively to Unit 21.
What this means practically: trophy-class pronghorn have been taken in this area, and the habitat supports the kind of mature buck development that produces exceptional animals. Hunters with a specific focus on a record-book buck should research the unit's buck-to-doe ratio and hunting pressure dynamics carefully — finding the oldest, heaviest-horned animals requires effort and glassing time regardless of the county's historical production.
Herd Health & Population Trends
Wyoming Game and Fish conducts aerial and ground surveys to track pronghorn herd composition. For Unit 21, survey data across four years from 2021 through 2024 shows an average buck-to-doe ratio of 48:100.
A 48:100 buck-to-doe ratio is a healthy benchmark for a managed antelope herd. Ratios in this range indicate that hunting pressure has not stripped the adult buck age class down to unproductive levels, and that enough mature animals are present to maintain competitive breeding dynamics during the September rut period. Pronghorn rut peaks in mid-September, and a balanced herd with mature bucks present means hunters have legitimate opportunities to glass and stalk rutting activity.
Four survey years of data showing a consistent average suggests this is not a single-year outlier but a genuine reflection of the herd's composition. Combined with the harvest data, the picture that emerges is a unit with a functioning, productive herd — even if 2025's lower success rate signals some tightening at the margins.
Access & Terrain
Unit 21 covers 400,422 total acres with 54% classified as public land — approximately 216,000 acres open to public access without permission. That figure puts Unit 21 solidly in the DIY-accessible tier. The majority of the unit is huntable ground for hunters willing to read maps, identify public boundaries, and cover country on foot.
The elevation range of 4,586 to 8,562 feet is notable. Pronghorn are primarily creatures of the lower to mid-elevation sagebrush and grassland zones, so hunters should focus their scouting on terrain below the upper elevation break. The unit's lower reaches will hold the bulk of the antelope population, particularly in the open flats and rolling terrain where these animals thrive and can be spotted at distance with quality optics.
There is no designated wilderness within Unit 21, which means nonresident hunters face no Wyoming outfitter requirement for this unit. DIY nonresidents can access all public land without hiring a licensed guide, making Unit 21 one of the more practical nonresident DIY antelope options in the state.
Private land does account for approximately 46% of the unit. Hunters should load mapping software before the season, confirm public land boundaries carefully, and make the effort to knock on doors for access permissions where private parcels interrupt otherwise accessible terrain. Some of the best antelope country in Wyoming sits adjacent to private ground — landowner permission can dramatically expand a hunter's effective range.
HuntPilot Analysis
Is Wyoming Unit 21 worth applying for?
For most hunters — yes, with appropriate expectations.
The unit's four-year harvest average sits in the upper-60% range when the entire window is considered, which is genuinely good performance for a pronghorn tag that draws competition from hundreds of applicants. The 2025 dip to 55% bears watching but does not change the unit's fundamental character. A herd with a 48:100 buck-to-doe ratio and an extensive county-level trophy history is a unit where patient, capable hunters find success.
For resident hunters: Unit 21 offers a strong value proposition. Wyoming residents accumulate preference points for pronghorn, and this unit — depending on where it sits in the current point curve — may be drawable with modest point accumulation. The tag fee structure for residents is highly affordable, making it a low-stakes application with meaningful upside.
For nonresident hunters: The draw is more competitive, and the nonresident tag fee structure reflects that. With no wilderness requirement and 54% public land, the DIY logistics are favorable. Nonresidents should go in with a full map strategy, a backup glassing plan, and realistic expectations about the work involved in identifying mature bucks among a larger population.
The honest caveat: Unit 21 is a volume unit. Several hundred hunters participate annually. That level of pressure means the largest, oldest bucks will not be standing in the open waiting to be walked up on. Glassing discipline, early-season scouting, and a willingness to cover miles of public ground separates hunters who fill tags on mature bucks from those who settle for first-legal.
For hunters whose primary goal is filling the freezer, Unit 21's historical success rates make it a strong option. For trophy-focused hunters, the county-level record history is encouraging — but expect to work for it.
How to Apply
Wyoming pronghorn tags are drawn through the Wyoming Game and Fish Department's application system. Hunters apply through the state's licensing portal, and preference points accumulate for Wyoming pronghorn — meaning applicants who do not draw a tag in a given year bank a point toward future applications.
2026 Application Details
For 2026, applications open January 2, 2026, with a deadline of June 1, 2026. A preference point-only deadline of November 2, 2026 allows hunters who miss the tag draw to still purchase a point for the year.
Resident fees (2026):
- Application fee: $5
- Tag fee: $22 (one tag tier) or $37 (second tag tier, depending on hunt)
- License fee: $0.00 required to apply
Nonresident fees (2026):
- Application fee: $15
- Tag fee options: $34 (one tier), $326 (second tier), or $1,200 (premium/limited draws) — depending on the specific hunt applied for
- License fee: $0.00 required to apply
- Preference point fee: $31 (for point-only applicants or those purchasing a point alongside their application)
The multiple nonresident tag fee tiers reflect the different draw pools available — from general/management hunts at the lower end to highly limited premium hunts at the $1,200 tier. Hunters should review each hunt's specific allocation and associated fee on the Wyoming Game and Fish website to ensure they're applying in the correct category for their goals.
2028 Application Details
For hunters planning further ahead, the 2028 application deadline is March 1, 2028, with applications opening January 5, 2028. Note that the 2028 deadline structure uses a March close rather than the June close in effect for 2026 — always verify the current year's deadline before assuming prior-year dates apply.
Wyoming does not require a base license to apply for pronghorn in the current structure (license fee listed as $0.00), but hunters should confirm current requirements at the time of application, as licensing requirements can change between regulation cycles.

Frequently Asked Questions
What is the harvest success rate in Wyoming Unit 21 for pronghorn?
Over the four most recent seasons (2022–2025), Unit 21's harvest success has ranged from 55% to 72%, with an average across that window in the upper-60% range. The most recent season (2025) came in at 55% across 387 hunters, which is the lowest of the four-year window. Hunters researching this unit should treat the full trend — including the recent decline — rather than cherry-picking the peak years.
What is the terrain like in Wyoming Unit 21 for pronghorn hunting?
Unit 21 spans 400,422 acres across an elevation range of 4,586 to 8,562 feet. Pronghorn occupy the lower-to-mid elevation zones — open sagebrush flats and rolling terrain where visibility is high and animals can be glassed at distance. The unit's 54% public land gives DIY hunters a meaningful base of accessible ground, and the absence of any designated wilderness removes the Wyoming guide requirement that affects nonresidents hunting other units.
How big are the pronghorn in Wyoming Unit 21?
The counties overlapping Unit 21 have an extensive history of trophy-class pronghorn production. While specific scores and entry counts are intentionally excluded here (and trophy records are shared across all units within overlapping counties, not exclusive to Unit 21), the area has a genuine track record of producing mature, record-eligible bucks. Hunters targeting a true trophy-quality animal should plan for serious glassing effort and expect that the largest bucks require patience, early scouting, and a willingness to pass on younger animals.
Is Wyoming Unit 21 worth applying for?
Yes, for most applicants — with realistic expectations. The unit produces consistent harvest numbers across several hundred hunters per year, carries a healthy average buck-to-doe ratio of 48:100 from recent surveys, and has a well-documented trophy history in the surrounding counties. The 2025 success rate dip to 55% is worth monitoring, but even at that level, Unit 21 outperforms many comparable Wyoming pronghorn units. Nonresidents benefit from the unit's DIY-friendly structure — 54% public land and no wilderness guide requirement.
What is the buck-to-doe ratio in Wyoming Unit 21?
Survey data from 2021 through 2024 shows an average buck-to-doe ratio of 48:100 across four survey years. This is a healthy ratio for a managed pronghorn herd and indicates a functioning adult buck age class capable of supporting sustainable hunting pressure. Hunters targeting rutting activity should be aware that pronghorn rut peaks in mid-September — timing hunts around this window gives the best opportunity to locate and pattern mature bucks.
