Weapon class
Rifle outpaces muzzleloader outpaces archery in nearly every unit. The math is range × shot opportunity. A bull at 280 yards is a rifle bull and not an archery bull.

What success rate actually means.
Hunters who tagged out — divided by hunters who hunted. Not the same as kill rate. Not the same as opportunity rate. Here's how to read the number, what moves it, and what it can and can't tell you.
The short version
Statewide bull elk success in Colorado runs in the high teens to low twenties percent.
The exact number CPW publishes in any given year depends on the weapon class, the season, the unit, and whether the harvest is counted as bulls-only or includes cows. Rifle 3rd typically posts the highest single-season number; archery and rifle 4th sit lower.
Guided private-land hunts on limited-entry units like GMU 59 run materially above the public-land DIY average. The gap is access and patterning, not marketing — outfitters spend the whole year scouting and managing the land the guests will hunt for six days.
Plain-English definitions
Four rates. Four different stories.
- Harvest rate
- Hunters who tagged out ÷ hunters in the field. The standard published number.
- Opportunity rate
- Hunters who got a shot or a serious stalk ÷ hunters in the field. Always higher than harvest rate. Outfitters often quote this separately.
- Encounter rate
- Hunters who saw elk during the season ÷ hunters in the field. Highest of the three; nearly 100% in good units.
- Trophy success rate
- Hunters who took a bull above a specific score (e.g., 300" B&C) ÷ hunters in the field. Always much lower than overall harvest rate; can be a small fraction of it.
When a friend at the gas station says “they have a 60% success rate” — ask which one they mean. Most people are conflating opportunity and harvest.
By season + weapon
Statewide ranges, three- to five-year rolling.
Approximate statewide bull elk success ranges by season, smoothed across multiple years to dampen single-year weather effects. Read these as orientation, not as quotes for any specific unit or year. For the current-year CPW figure on a specific unit, pull the unit summary at cpw.state.co.us/Statistics.
| Season | Typical range (statewide bulls) | Why |
|---|---|---|
| Archery (Sep 2 – Sep 30) | 10–18% | Bow range + September warmth + elk wariness during the rut. |
| Muzzleloader (Sep 12 – Sep 20, limited entry) | 15–25% | Iron-sight range opens it up; rut hangover keeps bulls vocal. |
| Rifle 1st (mid-Oct, limited entry) | 20–30% | Lower pressure than 2nd/3rd; elk haven't fully patterned hunters yet. |
| Rifle 2nd (late Oct) | 18–25% | Highest hunter density of any season; rifle range; elk pressured into timber. |
| Rifle 3rd (mid-Nov) | 22–32% | Cold pushes elk to south-facing benches; rifle range; rut hangover. |
| Rifle 4th (late Nov) | 18–28% | Snow can either concentrate elk or push them off the unit entirely. |
Ranges are author estimates based on multi-year CPW big game brochure data. Current-year unit-specific figures vary; always pull the authoritative number from CPW before planning around it.
How to read it honestly
Six steps before you trust any single number.
- 01
Understand the definition
Success rate is harvested animals ÷ tags filled (or hunters in the field, depending on the source). CPW publishes both. A 20% success rate means roughly one in five hunters tagged out — not that one shot in five connected.
- 02
Look at the right denominator
Statewide cow + bull combined is one number. Bull-only is lower. Bull-only on a specific weapon and season is lower still. When you see a single percentage on a forum, ask what's in the denominator.
- 03
Pair it with the weapon and season
Archery rut, muzzleloader shoulder, and the four rifle seasons all have different success rates. The widest gap is archery (typically lower) vs late-season rifle (typically higher in unit-specific data).
- 04
Separate public from private access
Private-land guided hunts run materially higher success rates because the cattle and fence work concentrates animals and the guides know where they bed. Public-land DIY in OTC units runs the lowest.
- 05
Discount year-to-year variance
A single bad weather year can drop a unit's number 15 points and a single good year can push it 20 points. Look at three- to five-year rolling averages, not a single season.
- 06
Use it to pick a unit, not a year
Success rate is a planning input. It tells you where to apply preference points; it doesn't tell you whether this November will be cold or open. Plan the unit; accept the weather.
What moves the number
Six variables. Each one can swing a unit 10+ points.
Season timing
Early rifle catches elk before they're pressured. Late rifle catches them when cold pushes movement. Archery catches them during peak rut behavior. Each timing favors a different tactic.
Public vs private access
Private land with cattle work and fence-line patterning runs higher. Public land in OTC units with high hunter density runs lower. Limited-entry public units fall between.
Guided vs DIY
Guides know where bulls bed in the unit you're hunting. A first-time DIY hunter doesn't. The first three days of a DIY hunt are scouting; a guide skips that step.
Weather year
A warm dry October keeps elk high and scattered. A snowy October pushes them down and concentrates them. The same unit can produce a 12% year and a 32% year back-to-back.
Hunter experience
Recovery rate, shot placement, and the willingness to keep glassing on day six all move success rates. The most-experienced quartile of hunters tags out at materially higher rates than the bottom quartile in the same unit.
The GMU 59 picture
Low pressure. Private land.
On GMU 59, 1st and 4th rifle bull elk are limited entry and 2nd and 3rd rifle are over the counter. The private and leased ground we hunt sits behind the ranch’s own gate, so it doesn’t see the truck traffic and orange suits that public OTC country does on opening weekend. That alone moves the success rate up versus the unmanaged average.
Elk Glade’s 2,100 family-owned acres and over 25,000 leased acres are country that we scout year-round between cattle moves. The bulls bed in pockets we know by name, water at three spring-fed creek runs we walk weekly, and travel benches we’ve patterned across four generations of family hunting.
Our annual harvest report (publishes every February with the prior-season’s real numbers) lays out the specific opportunity, harvest, and trophy ranges by weapon and season for the Elk Glade book of hunts. The CPW unit-level summary is the public-data benchmark.
FAQ
Specific questions, specific answers.
What is the average Colorado elk hunting success rate?
Colorado Parks and Wildlife publishes statewide elk harvest success rates that typically fall in the high teens to low twenties percent across all hunters and all seasons. Bull-elk-only success runs lower; cow harvest runs higher because cow tags are more available. Specific units and seasons can move 10+ points in either direction depending on weather, access, and weapon.
Which season has the highest success rate?
In most Colorado units, the third rifle season (mid-November) posts the highest bull elk success rate. Cold and incoming snow concentrate elk on south-facing benches, the rut hangover keeps bulls moving in daylight, and rifle range covers more country than archery or muzzleloader. Late seasons in specific units sometimes edge it out.
What is the archery elk hunting success rate in Colorado?
Archery elk success rates in Colorado typically run 10–18% statewide depending on the year and unit, materially below rifle. The September rut creates close-range opportunity, but bow range (20–60 yards) and elk wariness around heat and crowds keep tag-out rates lower than gun seasons.
Are guided elk hunt success rates higher than DIY?
Yes, materially. A reputable Colorado outfitter on private land typically runs 60–85% opportunity rates and 40–70% harvest rates for bulls, versus 10–25% for public-land DIY in heavily-hunted units. The gap comes from scouting time, access concentration, animal patterning, and the guide's ability to put you in country you couldn't find solo.
What is the GMU 59 elk hunting success rate?
GMU 59 (south slope of Pikes Peak) is limited entry for 1st and 4th rifle bull elk and over the counter for 2nd and 3rd rifle; the private ground Elk Glade hunts sees almost no outside pressure in any season. Elk Glade's private-land guided hunts on GMU 59 run materially above the public-land statewide average — exact ranges by season are published in our annual harvest report each February.
Does success rate include hunters who didn't fill a tag?
Yes. The standard CPW success rate is harvested animals divided by hunters in the field. A hunter who got a chance and missed, who saw bulls but couldn't close, or who never fired a shot all count as unsuccessful. This is why outfitters often quote 'opportunity rate' separately — the percentage of hunters who got a shot or a serious stalk.
