Montana Unit 670 Pronghorn Antelope Hunting Guide
Montana Unit 670 is one of the state's premier pronghorn antelope destinations, covering an expansive 2.6 million acres of prairie and shortgrass habitat in eastern Montana. With 53% public land access and elevations ranging from 2,057 to 3,313 feet, this unit offers the rolling, open terrain that pronghorn thrive in — and that hunters can glass effectively from distance. Harvest data from recent years tells a compelling story: in 2024, 314 hunters took to the field and 220 walked out with tags filled, a 70% success rate. In 2022, that rate climbed to 74% with 295 animals harvested out of 400 hunters. For a pronghorn permit in Montana, those numbers represent serious opportunity.
The unit's size alone sets it apart. At roughly 4,124 square miles, Unit 670 is large enough to spread hunting pressure thin even when permit numbers increase — which is relevant given that the Permit 20 pool grew from 300 tags in 2025 to 400 tags in 2026, a 33% increase. Whether that expansion reflects a healthy, growing pronghorn population or a deliberate management push toward increased harvest is worth tracking closely. Either way, hunters with a permit in hand will find a unit that has consistently delivered solid results.
For hunters researching where to invest their Montana pronghorn draw application, Unit 670 warrants a close look. The combination of accessible public land, high historical success rates, and moderate trophy potential makes it a legitimate contender across multiple applicant profiles — from nonresidents building points to residents looking for a reliable pronghorn tag.
Harvest Success Rates
Unit 670's harvest data is among the most useful planning tools available for this unit. Looking at the two most recent seasons with complete data:
- 2024: 314 hunters, 220 harvested — 70% overall success
- 2022: 400 hunters, 295 harvested — 74% overall success
These success rates are notably strong for a Montana pronghorn permit hunt. Even in 2024, when hunter numbers dropped from 400 to 314, the success rate held in the 70% range — suggesting the decline in participation didn't come at the expense of per-hunter opportunity. In fact, fewer boots in the field likely meant less competitive pressure on individual pronghorn herds within the unit.
For context, pronghorn are arguably the most predictable big game animal in North America to hunt once a hunter understands the terrain and herd distribution. Their open-country habits make glassing and stalking highly effective, and a 70%+ success rate in a unit of this size reflects both a healthy population and huntable country. Hunters willing to put in the scouting time — studying water sources, ridgelines, and fence crossings — will find that Unit 670 rewards preparation.
The unit does not have harvest data broken out by the B-Tag 30 and Permit 20 pools in the provided data, so hunters should consult the HuntPilot unit page for any pool-specific breakdowns.
Trophy Quality
The counties overlapping Unit 670 carry a moderate history of trophy records for pronghorn. This is not a unit that has historically dominated the upper tier of trophy production in Montana, but it is not barren of quality animals either. Trophy-class pronghorn have been taken from this area, and hunters with selective harvest goals have reason for cautious optimism.
Pronghorn trophy quality is heavily influenced by age structure and hunting pressure. In a unit seeing a significant tag increase — from 300 to 400 permits in the Permit 20 pool for 2026 — hunters focused on trophy potential should be aware that elevated harvest pressure can impact the ratio of mature bucks in the population over time. That doesn't make the unit a poor trophy destination, but it is a variable worth monitoring in future seasons.
Hunters targeting record-book-caliber pronghorn should understand that even in top-producing areas, truly exceptional animals are rare. The counties overlapping Unit 670 have moderate rather than exceptional trophy history, which means hunters should prioritize success and experience here, with the possibility of a quality buck as a realistic but not guaranteed outcome.
Herd Health & Population Trends
The most direct data point on Unit 670's pronghorn population health is the Permit 20 tag quota trend: 300 tags in both 2024 and 2025, increasing to 400 tags in 2026 — a 33% jump in a single regulation cycle. Montana Fish, Wildlife & Parks does not increase tag allocations without biological justification, which suggests the agency views Unit 670's pronghorn population as capable of sustaining higher harvest. This is an encouraging indicator of herd condition.
The B-Tag 30 pool has remained stable at 50 tags across 2024, 2025, and 2026, suggesting that antlerless management in the unit has been consistent and that the agency is not making dramatic adjustments to the female harvest component.
Taken together, the stable B-tag quota and significantly expanded Permit 20 quota paint a picture of a unit where pronghorn managers are confident in population trajectory. Hunters evaluating this unit should view the 2026 tag increase positively — it reflects biological optimism from the agency and also improves draw odds for applicants who may have struggled to access this unit in tighter quota years.
Access & Terrain
Unit 670 spans 2,639,375 acres with 53% public land — a meaningful majority, though hunters should understand that the public and private parcels in a unit this size are rarely uniformly distributed. Some drainages and flats will be dominated by public BLM or state land, while other sections will be checkerboarded or predominantly private. Effective access planning requires a mapping tool that identifies land ownership at the parcel level before heading afield.
Elevations of 2,057 to 3,313 feet place the unit squarely in the prairie and low-foothill topography characteristic of eastern Montana pronghorn range. This is not vertical terrain — hunters should expect rolling shortgrass prairie, sagebrush flats, coulees, and occasional rimrock. The unit contains no designated wilderness, meaning there are no guide requirements for nonresidents based on land classification. DIY nonresident hunters can access all public land in Unit 670 without hiring an outfitter (though private land access always requires landowner permission).
The open terrain cuts both ways. Long sight lines make glassing pronghorn at distance straightforward — this is country where quality optics and a solid stalking plan matter more than physical conditioning or pack-in logistics. At the same time, open country means pronghorn can see hunters just as easily, and sloppily executed approaches often end in spooked herds. Hunters should plan to use coulees, terrain breaks, and wind to their advantage.
Water sources in this semi-arid zone are important congregation points, particularly in drier years. Scouting for active water in late summer and early fall will pay dividends when the season opens.
HuntPilot Analysis
Is Unit 670 worth applying for? Based on the available data, the answer is yes — with appropriate expectations calibrated to the draw bucket and applicant profile.
The Permit 20 pool is the primary draw hunt for Unit 670 pronghorn. The 2026 quota increase from 300 to 400 tags is the most significant development for this unit heading into the upcoming cycle. More tags generally translates to improved draw odds across all applicant categories. For residents, this hunt has historically been accessible with modest point investment, and the expanded quota only improves that picture. For nonresidents, the competitiveness of this draw depends heavily on current applicant volumes — check the HuntPilot unit page at huntpilot.ai/states/mt for current draw odds.
The B-Tag 30 pool is stable at 50 tags. This antlerless permit serves a different management purpose and is worth considering for hunters primarily interested in filling the freezer.
The 70–74% harvest success rates across recent seasons are among the stronger figures you'll find for any Montana limited-entry pronghorn unit. The moderate trophy history suggests this isn't the unit to burn a maximum-point application on if elite trophy quality is the sole objective — but for hunters seeking a reliable, high-probability pronghorn experience with a realistic shot at a quality buck, Unit 670 delivers.
The 53% public land base and complete absence of wilderness designations make it a practical DIY unit for both residents and nonresidents. Hunters who do their pre-season scouting and understand how pronghorn use the terrain will be well-positioned to capitalize on a tag here.
Bottom line: Unit 670 is a strong choice for any hunter looking for a legitimate pronghorn permit with high harvest probability and adequate public access. The 2026 quota increase makes this a particularly interesting application cycle to target.
