Vihtavuori N110 is the fastest-burning powder in the Vihtavuori N100 rifle series – a single-base, small-grain extruded powder that occupies one of the most unusual positions in the entire powder market. Its burn rate places it in the same general territory as Hodgdon H110 and Alliant 2400 – fast enough for magnum handgun cartridges, fast enough for small-bore rifle cases with inherently small powder volumes like 22 Hornet, and specifically well-matched to the 300 Blackout supersonic load requirements. What separates it from those competitors is single-base chemistry, Finnish manufacturing quality, and temperature stability that single-base extruded powders inherently deliver – a combination that none of the primary ball powder alternatives at this burn rate can match.
The primary applications of N110 are genuinely diverse: 300 Blackout supersonic loads for AR-15 platforms, 22 Hornet precision varmint loading, 30 Carbine, 357 Magnum at full pressure in both revolvers and carbines, and 44 Magnum with heavy bullets for hunting applications. The logic that unites these applications is the case-volume-to-bore-diameter relationship: all of these cartridges share a characteristic of relatively small case volume relative to their bore or operational requirements, where a fast-burning powder with high energy per gram is the right tool.
Powder Description and Technical Profile
Vihtavuori N110 is a single-base, small extruded cylindrical powder manufactured at Eurenco Vihtavuori’s facility in Vihtavuori, Finland. Eurenco Vihtavuori controls the full production chain from nitrocellulose to finished powder – the same vertically integrated manufacturing that underpins the lot-to-lot consistency of Vihtavuori N133 and other N-series powders.
The single-base formulation – nitrocellulose without nitroglycerin – is the foundation of N110’s most valued properties. Without nitroglycerin:
- Flame temperature is lower than double-base alternatives at the same burn rate. In a high-pressure 44 Magnum revolver or a heavily used 300 Blackout suppressed rifle, lower flame temperature means measurably less throat erosion and barrel wear over high round counts
- Temperature stability is inherently superior because the energy release mechanism involves fewer chemically reactive compounds. The nitroglycerin in a double-base powder like H110 has a different temperature coefficient than the nitrocellulose base, and their interaction changes as temperature varies. Single-base powders avoid this interaction
- Cleaner combustion at appropriate pressures because there are no heavy deterrent coatings masking the grain surface. The consistent nitrocellulose grain burns completely without the residue contributions that thick deterrent coatings in ball powders can produce
Grain dimensions are 0.8 mm length × 0.8 mm diameter – essentially cubic short cylinders. This small, uniform grain geometry provides several practical advantages: good case fill even in small-capacity cases like 22 Hornet where the powder column needs to be packed consistently against the primer, and reasonably predictable metering through quality volumetric measures despite being an extruded powder.
Bulk density is 800 g/l (0.800 g/cc) – notably lower than the ball powders it competes with in this burn rate range (H110 at 0.940 g/cc, Alliant 2400 at 0.873 g/cc). This lower density means more powder volume per unit of case capacity. In 300 Blackout supersonic loads with 110-125 grain bullets, N110 fills the case well at working charge weights – important for consistent ignition and low velocity standard deviation.
The energy content of 3,950 J/g is the highest in the Vihtavuori N100 series, despite being single-base. This reflects the nitrocellulose formulation used – high-energy single-base propellants can approach double-base energy levels through specific cellulose chemistry choices, and Vihtavuori’s formulation achieves this while maintaining the stability benefits of single-base chemistry.
Strengths:
- Temperature stability of 0.4-0.6 fps per degree Fahrenheit – genuinely excellent for a fast-burning powder, and substantially better than double-base alternatives like H110 (~1.2-1.5 fps/°F) in the same burn rate position
- Single-base cleanliness – burns with minimal residue at operating pressures, particularly beneficial in suppressed 300 Blackout rifles where residue in the suppressor accumulates with every shot
- Lower flame temperature than double-base alternatives – measurably extends barrel and throat life in high-volume applications
- Finnish lot-to-lot manufacturing consistency from Vihtavuori’s vertically integrated production
- Does not always require magnum primers – the single-base extruded grains ignite more reliably at lower primer energy than thick-deterrent-coated ball powders, which sometimes allows standard primers to produce tighter standard deviations than magnum primers in moderate-capacity cases
- Effective at slightly below maximum pressure – unlike H110 which requires near-maximum pressure for clean combustion, N110 burns efficiently across a broader pressure range
Limitations:
- Lower bulk density (0.800 g/cc) than most double-base competitors – occupies more case volume per grain of charge, which can limit maximum achievable charge weights in some applications
- Premium price point – Vihtavuori powders carry a consistent cost premium over domestic US alternatives; for high-volume practice loading, the economics can be a consideration
- North American availability requires specialty importers and advance inventory planning
- Small extruded grains still meter less consistently than ball powders – ±0.1 grain on quality equipment is achievable but requires controlled measure cycling speed; ball powders are more forgiving at progressive press cycling rates
- Cannot match the absolute maximum velocity ceiling of high-nitroglycerin double-base powders at the same burn rate in applications where maximum velocity is the singular objective

The N110 Burn Rate Position – Context in the Vihtavuori Lineup
Vihtavuori N110 is the fastest-burning rifle powder in the N100 series. The N100 series runs from N110 through increasingly slower powders:
| Powder | Burn Rate | Primary Application |
|---|---|---|
| Vihtavuori N110 | Fastest | 22 Hornet, 300 BLK, magnum revolvers |
| Vihtavuori N120 | Fast | 300 BLK, 22 Hornet alternate |
| Vihtavuori N130 | Medium-Fast | 6mm BR, 222 Rem |
| Vihtavuori N133 | Medium-Fast | 223 Rem, 6mm PPC |
| Vihtavuori N135 | Medium | 223 Rem (heavy), 308 Win |
| Vihtavuori N140 | Medium-Slow | 308 Win, 30-06 |
| Vihtavuori N150 | Slow | 30-06, 270 Win |
The critical practical implication of N110’s position as the fastest N-series powder: it is too fast for 223 Remington with standard 55-62 grain bullets. The N120 or N133 are the appropriate Vihtavuori choices for standard 223 Remington applications. N110 belongs in the smallest cases and the magnum revolver applications where its fast burn rate is well-matched.
Temperature Stability – Why It Matters for N110’s Applications
0.4-0.6 fps per degree Fahrenheit from a fast rifle powder is exceptional. To understand why this specific property matters so much in N110’s primary applications, consider two scenarios:
Suppressed 300 Blackout hunting: A hunter using a suppressed 300 Blackout for predator control develops a 110-grain supersonic load in October at 55°F. The same rifle is used in January at 10°F and on a warm April afternoon at 75°F. With H110 at 1.2-1.5 fps/°F, the 65°F swing from January to April produces 78-98 fps of velocity variation – enough to affect point-of-impact at longer distances. With N110 at 0.4-0.6 fps/°F, the same swing produces 26-39 fps – well within the margin that maintains consistent practical accuracy.
Metallic silhouette shooting with 44 Magnum: Silhouette competition involves shooting steel targets at 50-200 meters with a revolver, often across several months of competition at variable outdoor temperatures. A double-base ball powder load that chrono’d comfortably within power floor at a 70°F fall match may fall below power floor at a 30°F winter match. N110’s stability keeps the load within the same power band across seasons without needing separate cold-weather and warm-weather load development.
| Powder | Stability | Application Relevance |
|---|---|---|
| Vihtavuori N110 | 0.4-0.6 fps/°F | Best in class for this burn rate position |
| Alliant 2400 | ~0.8-1.0 fps/°F | Good – single-base, similar logic |
| Hodgdon H110 | ~1.2-1.5 fps/°F | Moderate – double-base ball |
| Accurate No. 9 | ~1.4-1.6 fps/°F | More sensitive – double-base ball |
| Hodgdon Lil’Gun | ~1.0-1.4 fps/°F | Moderate – double-base ball |
Burn Rate Comparison and Competing Powders
| Powder | Type | Density (g/cc) | Key Character |
|---|---|---|---|
| Accurate No. 9 | Double-Base Spherical | 0.950 | Faster – ball metering, temperature sensitive |
| Vihtavuori N110 | Single-Base Extruded | 0.800 | Reference |
| Alliant 2400 | Single-Base Extruded | 0.873 | Similar – single-base, traditional |
| Vihtavuori N120 | Single-Base Extruded | 0.860 | Similar-Faster – 300 BLK, 22 Hornet |
| Hodgdon H110 | Double-Base Spherical | 0.940 | Slightly Slower – higher velocity, needs max pressure |
| Hodgdon LilGun | Double-Base Spherical | Medium | Slightly Slower – versatile magnum |
| IMR 4227 | Single-Base Extruded | 0.920 | Slower – 300 BLK subsonic, heavy bullets |
vs. Hodgdon H110: The most common comparison. H110 is a double-base ball powder at a slightly slower burn rate. It produces higher absolute velocities in 44 Magnum and 357 Magnum at maximum pressure from its nitroglycerin energy content. Its known limitation is that it must be loaded at or near maximum pressure for clean, complete combustion – reduced loads with H110 in magnum cases frequently produce dirty burning and elevated standard deviations. N110 burns efficiently across a broader pressure range and produces significantly less temperature-induced velocity variation. For a hunter or competitor who shoots year-round across varying temperatures, N110’s stability is the more valuable property. For maximum chronograph numbers in a single-temperature load development session, H110 has the velocity edge.
vs. Alliant 2400: Alliant 2400 is also a single-base extruded powder at a comparable burn rate with a long documented history in 22 Hornet and 44 Magnum. It has a deep published data library in North American manuals. N110 produces less muzzle flash and residue than 2400 in equivalent applications – a well-documented difference between the two powders. For suppressed 300 Blackout where muzzle flash is irrelevant but residue accumulation in the suppressor matters, N110 is the cleaner choice. For outdoor unsuppressed use where residue accumulation between cleanings is managed anyway, 2400 provides a deeper data library at a lower price point.
vs. Accurate No. 9: Accurate No. 9 is a double-base spherical powder at a faster burn rate than N110, primarily for 357 Magnum and 10mm Auto applications. Its ball geometry meters consistently through progressive presses – better than N110’s extruded grains for high-volume production. Temperature sensitivity is notably higher (~1.4-1.6 fps/°F vs N110’s 0.4-0.6 fps/°F). For high-volume 357 Magnum training ammunition loaded on a progressive press where seasonal consistency is secondary, Accurate No. 9 has the metering advantage. For competition and hunting use where consistent point-of-impact across seasons matters, N110 is more appropriate.
vs. Vihtavuori N120: N120 burns slightly faster than N110 in the Vihtavuori chart positioning and is also well-documented for 300 Blackout and 22 Hornet applications. The two powders overlap significantly in their optimal applications. Load development in your specific rifle and bullet combination is the most reliable guide to which produces better accuracy nodes in the applications where both have published data.
The Standard Primer Advantage
One of the most practically useful – and most counterintuitive – characteristics of Vihtavuori N110 is that standard primers often produce tighter standard deviations than magnum primers in the small-to-medium capacity cases where it operates.
The explanation: double-base ball powders like H110 have thick deterrent coatings that require intense primer energy to penetrate and initiate consistent combustion. A standard primer may ignite the exterior grain surfaces inconsistently across shots, producing velocity variation. A magnum primer provides enough energy to penetrate the deterrent coating reliably, improving consistency – hence the well-known recommendation to use only magnum primers with H110.
N110 has no heavy deterrent coating. Its single-base extruded grains expose uncoated nitrocellulose that ignites readily at standard primer energy levels. With a magnum primer, the excess brisance can actually destabilize ignition by producing a blast that unseats the bullet from the case neck fractionally before the powder fully ignites – creating a micro-variation in start pressure that shows up as elevated standard deviation. A standard primer that precisely initiates combustion without excess energy produces more consistent ignition and lower SD numbers.
The practical guidance: for most 300 Blackout, 22 Hornet, and 30 Carbine applications with N110, start load development with standard small rifle primers before defaulting to magnum primers. For 44 Magnum and 357 Magnum with large-primer cases, large pistol standard primers often produce excellent results before magnum pistol primers are needed. Verify against Vihtavuori’s published load data for specific primer recommendations in each application.
Recommended Cartridges and Applications
| Cartridge | Primary Application | Notes |
|---|---|---|
| 300 Blackout | Supersonic 110-125 gr | Primary modern application |
| 22 Hornet | Varmint precision 35-55 gr | High case-fill consistency |
| 30 Carbine | Standard 110 gr | Clean cycling in M1 Carbine |
| 357 Magnum | Full pressure hunting and silhouette | Standard primer often preferred |
| 44 Magnum | Hunting loads with heavy bullets | Full-pressure specialty |
| 454 Casull | High-pressure big game defense | Large pistol magnum primer required |
| 44 Special | Moderate hunting loads | Reduced charge from 44 Mag data |
The 300 Blackout supersonic application is where N110 has built its modern reputation. The 300 Blackout case was specifically designed to work in a standard AR-15 lower with a modified upper, and the supersonic load requirement (110-125 grain bullets at 1,900-2,150 fps) places specific demands on powder selection. The case volume available for powder is moderate, and the gas system timing of an AR-15 requires consistent port pressure from each shot. N110 delivers both: adequate case fill for consistent ignition and a pressure curve that cycles the bolt carrier group reliably without over-gassing the system.
For suppressed 300 Blackout specifically, N110 is among the cleaner-burning powders available. Suppressors accumulate carbon and solids from combustion byproducts, and powder choice significantly affects cleaning interval. N110’s complete, clean combustion at operating pressure reduces accumulation noticeably compared to double-base ball powders in the same application.
The 22 Hornet application reflects the case-volume principle: the Hornet holds only 13 grains of water capacity. At that scale, having a powder that fills the case completely and burns consistently even in cold-weather varmint use is a genuine accuracy advantage. N110’s small grain size packs into the Hornet case with minimal void space, and the temperature stability keeps the load consistent from spring to late-fall varmint seasons.
Bullets
Vihtavuori N110 works best with light-to-standard bullet weights in its rifle cartridge applications and heavy hunting bullets in its magnum revolver applications. The fast burn rate is specifically suited to bullets that generate adequate start pressure in small cases.
| Brand | Model | Weight | Cartridge | Application |
|---|---|---|---|---|
| Hornady | V-MAX | 35-55 gr | 22 Hornet | Varmint Precision |
| Hornady | NTX | 35-40 gr | 22 Hornet | Lead-Free Varmint |
| Sierra | MatchKing | 110-125 gr | 300 Blackout | Match Supersonic |
| Nosler | Ballistic Tip | 40-55 gr | 22 Hornet | Hunting Precision |
| Barnes | TSX | 110 gr | 300 Blackout | Lead-Free Hunting |
| Lapua | Scenar | 110-123 gr | 300 Blackout | Competition Precision |
| Hornady | XTP | 158-180 gr | 357 Mag / 44 Mag | Hunting Revolver |
| Sierra | Sports Master | 158-180 gr | 357 Mag / 44 Mag | Competition / Hunting |
| Nosler | Partition | 180-240 gr | 44 Magnum | Big Game Hunting |
| Lehigh Defense | Xtreme Penetrator | 140-160 gr | 357 Mag / 44 Mag | Hard-Cast Defense |
| Nosler | AccuBond | 110 gr | 300 Blackout | Hunting Precision |
One specific note on 300 Blackout bullet weight selection with N110: the powder is specifically well-matched to 110-125 grain supersonic bullets. At 150+ grain bullets in 300 Blackout, the optimal application shifts toward subsonic loads where different powders – particularly IMR 4227 and purpose-built subsonic propellants – are more appropriate. N110 is a supersonic 300 Blackout powder.
Primers
The primer selection guidance for N110 is more nuanced than for most powders because the single-base, coating-free grain structure changes how primer brisance interacts with ignition. The general principle: start with standard primers and upgrade to magnum only if load development data indicates incomplete ignition (elevated ES, sooty case necks, inconsistent velocity).
| Primer | Type | Application |
|---|---|---|
| CCI 400 | Small Rifle Standard | 22 Hornet, 300 BLK general development |
| Federal 205 | Small Rifle Standard | Match-grade consistency for small cases |
| CCI BR-4 | Small Rifle Benchrest | 22 Hornet benchrest precision |
| Winchester WSR | Small Rifle Standard | 30 Carbine, 300 BLK general use |
| Remington 7-1/2 | Small Rifle Bench Rest | Small-case maximum precision |
| CCI 450 | Small Rifle Magnum | Cold weather below 15°F, 300 BLK dense loads |
| CCI No. 41 | Small Rifle Magnum (Mil-Spec) | AR-15 semi-auto 300 BLK |
| RWS 4033 | Small Rifle | Premium European precision option |
| CCI 500 | Small Pistol Standard | 357 Magnum standard pistol primer applications |
| Federal 150 | Large Pistol Standard | 44 Magnum in standard conditions |
| CCI 350 | Large Pistol Magnum | 44 Magnum cold weather, 454 Casull |
| Federal 215 | Large Rifle Magnum | 454 Casull maximum pressure |
| Fiocchi Small Rifle | Small Rifle Standard | Consistent European alternative |
For AR-15 300 Blackout semi-automatic platforms, the CCI No. 41 mil-spec primer cup prevents slam-fire from a free-floating firing pin – the same requirement as for any semi-auto 223 Remington loading.
The neck tension note from the original article is genuinely important for N110 specifically: consistent case neck tension is the mechanical complement to the standard primer approach. If neck tension varies between rounds – from inconsistent case sizing, mixed brass, or uneven annealing – the powder’s start pressure varies even with identical charge weights and primers. Consistent sizing die setup and periodic annealing produce the uniform neck tension that allows N110’s ignition consistency to be fully realized.
Metering and Equipment Compatibility
Vihtavuori N110 meters with the typical behavior of a small extruded powder – better than larger-kernel stick powders, not as consistent as ball powders. Quality volumetric measures produce charge-to-charge variance of ±0.1 grains at controlled cycling speeds. At progressive press cycling speeds where the measure handle is moved quickly, variance can increase to ±0.15-0.2 grains.
For precision 22 Hornet and benchrest loading where charge weights run 10-14 grains, a Frankford Arsenal Powder Trickler with a high-resolution scale like the Frankford Arsenal Precision Digital Scale or RCBS MatchMaster is the appropriate precision approach. At 13 grains of charge, individual N110 kernels weigh approximately 0.05-0.08 grains – suitable single-kernel resolution for manual trickling to ±0.02 grains per charge.
For 300 Blackout and magnum revolver loading at 15-25 grain charge weights, the Redding Competition BR-30 and Lyman Brass Smith Powder Measure handle the small grain geometry with adequate consistency for most applications. Auto-dispensers including the Hornady Auto-Charge Pro and RCBS ChargeMaster Link dispense N110 efficiently at these charge weights.
Reloading Safety Notes
Fast-burning powders in small cases build pressure rapidly. The margin between starting load and maximum is narrower with N110 than with medium-burn powders in larger cases. Work up in 0.2-grain increments (not 0.3) given the small total charge weight range in primary applications.
All charge weights must come from current published Vihtavuori load data for N110 specifically. Vihtavuori publishes comprehensive data online with regular updates. Do not substitute H110 or Alliant 2400 charge weights for N110 without independent verification – the density difference (0.800 g/cc vs 0.940 g/cc for H110) means charge volumes differ significantly, and burn rate proximity does not guarantee interchangeable charge weights.
For magnum revolver applications, the cylinder gap in a revolver allows combustion gas to escape at the cylinder-barrel junction. With fast powders and full-pressure loads, this is a normal design feature, not a safety concern. It does affect metering requirements: load data for revolvers is developed in revolvers, not semi-automatics, and the pressure at the gas port timing in a revolver cycle differs from a semi-automatic action.
See the overpressure in reloading guide for systematic pressure sign identification across cartridge types.
FAQ
Why does N110 not always need a magnum primer?
N110’s single-base extruded grains have no heavy deterrent coating. The uncoated nitrocellulose surface ignites readily at standard primer energy levels. A magnum primer’s excess brisance can actually unseat the bullet microscopically before the powder fully ignites, creating start-pressure variation. Standard primers in moderate-capacity cases with N110 often produce lower standard deviations than magnum primers. In large cases (large pistol primer applications) or extreme cold below 15°F, step up to magnum primers.
Can N110 be used for subsonic 300 Blackout?
No – N110 is specifically the supersonic 300 Blackout powder. Subsonic 300 Blackout uses 200-220 grain bullets at velocities below 1,050 fps with very fast powders at very low charges – a fundamentally different powder requirement. Attempting subsonic loads with N110 produces incomplete combustion, squib risk, and inconsistent velocities. IMR 4227, Accurate 1680, and dedicated subsonic powders are the appropriate choices for subsonic 300 Blackout.
How does N110 compare to N120 in 300 Blackout?
Both are in the Vihtavuori N-series with comparable burn rates for 300 Blackout supersonic applications. N120 burns slightly faster in Vihtavuori’s burn rate ordering. Both carry the same manufacturing quality and temperature stability credentials. The practical answer is to develop loads from both against Vihtavuori’s published data for your specific bullet and determine which produces better accuracy nodes in your barrel.
Is N110 appropriate for 357 Magnum in carbine-length barrels?
Yes – 357 Magnum carbines (Marlin 1894, Henry, lever-action formats) with 16-18 inch barrels use small rifle primers and can take advantage of N110’s clean burning and temperature stability. The longer barrel extracts more velocity than a revolver, and the clean-burning characteristics reduce maintenance intervals in tubular magazines and lever mechanisms. Use small rifle primer data specifically – it differs from large pistol primer data for the same cartridge.
Conclusion
Vihtavuori N110 earns its specialized reputation through a combination of properties that competing powders at this burn rate cannot simultaneously provide: single-base temperature stability, Finnish manufacturing consistency, clean combustion without heavy residue, and the ability to operate effectively without magnum primers in many applications.
It is not the maximum-velocity choice – double-base ball powders produce more fps in 44 Magnum and 357 Magnum at maximum pressure. It is not the easiest-metering choice – ball powders flow more consistently through progressive presses. What it is, consistently, is the most temperature-stable and cleanest-burning fast powder available for the specific applications where those properties matter most.
Choose Vihtavuori N110 if you load 300 Blackout supersonic for suppressed use, 22 Hornet varmint precision, or 357 Magnum and 44 Magnum for year-round competition or hunting where temperature consistency matters. Choose Hodgdon H110 if maximum velocity in magnum revolver cartridges at a lower price point is the priority and you shoot at consistent temperatures. Choose Alliant 2400 if you want a single-base alternative with a deeper North American data library at a lower price point and can accept slightly more muzzle flash and residue. Choose Accurate No. 9 if high-volume 357 Magnum or 10mm Auto loading on a progressive press where ball powder metering is the priority.
