Wyoming Unit 103 Pronghorn Antelope Hunting Guide

Wyoming Unit 103 offers pronghorn antelope hunters a limited-quota opportunity across nearly 722,418 acres of high desert and sagebrush country, with elevations ranging from 4,212 to 10,213 feet. This dramatic elevation spread signals varied terrain within the unit, from lower-lying flats typical of prime pronghorn habitat to higher benches and ridgelines. For hunters weighing whether to spend points or apply fresh in Unit 103, understanding the hunt structure, recent harvest trends, and access realities is essential before committing an application.

Unlike many Wyoming pronghorn units that combine general season opportunity with supplemental draw tags, Unit 103 runs entirely on a limited-quota basis. There is no general season here — every hunt, including tags for antlered and either-sex animals, requires a successful draw. That distinction matters enormously for planning purposes, since hunters cannot simply buy an over-the-counter license and show up. Every hunter in this unit, resident or nonresident, has gone through the draw to be there, which tends to translate into somewhat more controlled hunting pressure relative to units where general tags are unlimited.

HuntPilot Analysis: Is Unit 103 Worth Applying For?

The harvest numbers coming out of Unit 103 make a strong case for this being a productive, reliable unit for hunters who can draw a tag. Success rates have held firm in a tight band over the past four years: 71% in 2025, 75% in 2024, 81% in 2023, and 81% in 2022. That kind of consistency — never dropping below 71% harvest success across four full seasons — indicates a stable pronghorn population and reasonably favorable hunting conditions rather than a boom-or-bust unit driven by drought or die-off years.

Hunter numbers have also stayed remarkably steady, ranging from 252 to 269 hunters annually, which suggests the quota has been managed conservatively and consistently rather than fluctuating wildly year to year. For a hunter using data from HuntPilot to compare units, that stability is a meaningful signal: Unit 103 isn't a unit where a single bad winter wiped out the population or where quotas have been slashed in response to herd stress.

Where hunters need to temper expectations is on the trophy side. The counties overlapping Unit 103 carry a moderate history of trophy-class pronghorn production — not a blank slate, but not a unit with an exceptional or standout trophy pedigree either. Hunters chasing a genuine record-book buck should treat Unit 103 as a solid opportunity unit with occasional trophy potential rather than a unit built around consistently producing top-end bucks. That trophy assessment is shared across the broader county area, not just this unit boundary, so neighboring units draw from the same pool of trophy history.

The buck:doe ratio from the 2021–2024 survey period averaged 30:100. That's a modest ratio by pronghorn standards and points toward a herd with solid doe numbers relative to bucks — common in units that see consistent buck harvest pressure through the draw system. It doesn't scream trophy production, but it does support the kind of dependable, moderate-to-high success rates the harvest data shows. Hunters should view this as a numbers-and-opportunity unit rather than a big-buck destination, though a mature buck is always possible given the terrain diversity here.

The bigger access caveat is public land. Only 25% of Unit 103 is public, meaning three-quarters of the unit sits in private ownership. That is a significant limiting factor for DIY hunters. This is not a unit where a hunter can show up and expect to wander freely across open public ground — successful hunters here will need to do serious homework on exactly where the public parcels lie, look hard at walk-in access programs, or pursue permission on private land. Hunters without a private land connection or a plan for accessing the public fraction should factor this into their expectations before applying, since the math on public acreage alone (roughly 180,000 of the 722,418 total acres) leaves a narrow margin for error in scouting and access planning.

Taken together: Unit 103 is worth applying for if a hunter's priority is a well-managed, statistically dependable hunt with strong odds of putting meat in the cooler, and is realistic about needing to secure access before the season. It's a weaker fit for the hunter whose sole goal is a trophy-class buck and who isn't willing to grind on private land access issues.

Harvest Success Rates

Unit 103's harvest data over the last four years is about as consistent as pronghorn hunting gets:

• 2025: 258 hunters, 183 harvested — 71% success
• 2024: 269 hunters, 203 harvested — 75% success
• 2023: 264 hunters, 213 harvested — 81% success
• 2022: 252 hunters, 204 harvested — 81% success

Success rates trended slightly downward from the 81% marks in 2022 and 2023 to 75% in 2024 and 71% in 2025, but even the most recent year still cleared 70%. That's a healthy success rate for pronghorn hunting anywhere in the West, and it suggests hunters who draw a tag here have a strong likelihood of filling it, assuming they've done the access legwork discussed above. The slight downward drift over the last two years is worth watching, but four straight years above 70% success is not something to dismiss — it reflects an accessible, huntable pronghorn population rather than a unit where tags go unfilled due to difficult terrain or scarce animals.

Trophy Quality

Trophy data for the counties overlapping Unit 103 points to moderate trophy potential. This isn't a unit with a deep or standout record-book history, but it isn't devoid of trophy-class animals either. Hunters should treat any mature buck taken here as a bonus rather than an expectation, and plan the hunt around the unit's strength — consistent success — rather than banking on a record-book pronghorn. Because trophy records are logged at the county level, this moderate trophy history is shared with other units overlapping the same counties, so it reflects a broader regional trend rather than something unique to Unit 103's boundaries alone.

Herd Health & Population Trends

The available survey data spans four years (2021–2024) and shows an average buck:doe ratio of 30:100. This is on the lower end for pronghorn herds, which often run higher in well-managed limited-quota units, but it aligns with a unit that sustains fairly heavy, consistent buck harvest through its draw-only structure. A 30:100 ratio doesn't indicate a herd in trouble — pronghorn populations can support this kind of ratio while maintaining strong fawn recruitment and overall herd stability — but it does reinforce that this is a unit managed for opportunity and harvest rather than for maximizing buck age structure. Hunters should view the survey data as consistent with the harvest trends: a unit producing solid numbers of huntable bucks each year rather than one stockpiling older-age-class animals.

Access & Terrain

Unit 103 spans a wide elevation range, from 4,212 feet up to 10,213 feet, across 722,418 total acres. That elevation swing suggests hunters could encounter everything from classic low sagebrush flats — the bread-and-butter pronghorn habitat — to higher, more broken ground at the unit's upper extremes. There is no wilderness acreage in this unit, so hunters don't need to worry about wilderness travel restrictions or, since this is Wyoming, the state's outfitter requirement that applies specifically to nonresidents hunting in designated wilderness areas.

The critical access number here is public land: just 25% of the unit is publicly owned. That means the majority of Unit 103 — roughly three-quarters of its acreage — is private property. DIY hunters need to treat this as a unit requiring real pre-season work: identifying exactly where public parcels sit relative to access roads, researching any walk-in or public access programs that may apply, and potentially lining up private land permission well before the season starts. This is not a unit where a hunter can count on expansive public ground to simply walk into on opening morning. Hunters serious about drawing Unit 103 should use mapping tools — including HuntPilot's public land layers — to scout exact parcel boundaries and plan routes before ever setting a boot on the ground.

How to Apply

Because Unit 103 has no general season, every hunter — resident or nonresident — must go through Wyoming's draw system to obtain a tag here, including for antlered and either-sex pronghorn. There is no over-the-counter option and no leftover-list shortcut that bypasses the draw for this unit's primary hunts.

Wyoming's draw structure separates resident and nonresident applicants into different pools, and nonresidents face a more competitive path overall given the state's tag allocation split. Wyoming also runs a preference point system for pronghorn, meaning nonresident (and resident) applicants who don't draw accumulate points that improve their standing in future application cycles, alongside a separate random draw pool that isn't influenced by point totals. Successfully drawing a tag resets a hunter's accumulated points for that species, so hunters should factor that into multi-year planning rather than assuming points carry forward indefinitely.

Given that Unit 103 is entirely draw-dependent, hunters should check current draw odds before applying rather than guessing based on point totals alone. Application structure, deadlines, and fees change every cycle, so for the most current numbers, deadlines, and application requirements, visit HuntPilot's Wyoming state page at /states/WY or the unit-specific page for Unit 103.

Frequently Asked Questions

What is the terrain like in Wyoming Unit 103? Unit 103 covers 722,418 acres with an elevation range from 4,212 to 10,213 feet, indicating a mix of lower sagebrush flats typical of pronghorn country and higher benches or ridgelines at the unit's upper extremes. There is no wilderness acreage in the unit, so access isn't restricted by wilderness travel rules.

What is harvest success like in Unit 103? Harvest success has been strong and consistent, ranging from 71% to 81% across the 2022–2025 seasons. The most recent year, 2025, saw 258 hunters harvest 183 animals for a 71% success rate, continuing a multi-year trend of hunters filling tags at a high rate once they draw.

How big are the pronghorn in Unit 103? Trophy data for the counties overlapping this unit points to moderate trophy potential — some history of trophy-class bucks, but not a standout record-book unit. Hunters should expect a realistic chance at a mature buck but shouldn't plan the hunt around drawing a trophy-caliber animal specifically.

Is Unit 103 worth applying for? For hunters prioritizing high odds of filling a tag, yes — four consecutive years of 70%+ success support that. The tradeoff is access: with only 25% public land, hunters need a solid plan for reaching huntable ground, whether through public parcel scouting or securing private land permission, before they draw.

What should hunters know about access before applying to Unit 103? With just 25% of the unit in public ownership, the majority of Unit 103 is private land. Hunters without existing private land access should use mapping tools to identify exact public parcel boundaries and consider walk-in access options well ahead of the season, since this unit is not one where open public ground dominates the landscape.
