Vihtavuori N130 is a fast-burning, single-base short-cut extruded powder from Vihtavuori (Nammo Group, Finland), positioned between Vihtavuori N120 (faster) and Vihtavuori N133 (slower) in the Finnish N100 rifle series. It occupies the burn rate position suited to small-bore benchrest precision cases and 223 Remington with light 40-52 grain varmint bullets – the range where the case volume requires a fast powder for efficient combustion but not as fast as N120 demands.
Like all powders in the Vihtavuori N100 series, N130 carries an integrated decoppering additive that chemically reduces copper jacket adhesion to the bore surface, and benefits from Vihtavuori’s single-facility Finnish manufacturing that produces the tight lot-to-lot consistency specifically valued in competition shooting.
The powder’s burn rate positions it as the intermediate step in the Vihtavuori fast-rifle lineup: faster than the N133 that is the 222 Remington benchmark, and slower than N120 that is optimized for the smallest cases. This makes N130 specifically appropriate for 222 Remington with standard bullet weights, 204 Ruger, and 223 Remington with light 40-52 grain loads.
This article is based on published manufacturer specifications, established load data, and documented field reports. Specifications and performance figures can vary between lots, rifles, and conditions.

Powder Description and Technical Profile
Vihtavuori N130 is a single-base, short-cut extruded powder. The single-base formulation – nitrocellulose without nitroglycerin – is the chemical basis for the temperature stability and clean-burning behavior that define the Vihtavuori N100 series.
The short-cut grain geometry (approximately 1.0 mm length x 0.6 mm diameter) is longer than N120’s micro-grains (0.8 mm x 0.6 mm) but significantly shorter than traditional long-stick extruded powders like IMR 4064 or IMR 4198. On quality volumetric equipment, charge-to-charge variance of approximately ±0.08-0.12 grains is achievable – better than standard extruded alternatives, not quite at N120’s micro-grain performance.
Bulk density is 0.870 g/cc – consistent with Vihtavuori’s single-base short-cut chemistry. Lower than ball alternatives at this burn rate class (Accurate 2015 at 0.895 g/cc), and slightly higher than N120 (0.840 g/cc).
Temperature stability is approximately 0.4-0.6 fps/°F – meaningfully better than double-base ball alternatives and comparable to other Vihtavuori single-base powders in this class. While not at Hodgdon Extreme series levels (~0.3 fps/°F for H4198), the 0.4-0.6 fps/°F performance is specific and credible for a high-quality single-base extruded product.
Strengths:
- Integrated decoppering additive – chemically reduces copper accumulation in the bore; specifically valuable for long varmint sessions in 204 Ruger and 222 Remington where copper fouling affects accuracy over extended strings
- Good temperature stability (0.4-0.6 fps/°F) – better than double-base alternatives at the same burn rate class; hunters zeroing in summer and hunting in cold conditions see manageable variation
- Single-base ultra-clean burning – minimal carbon per round; specifically relevant for high-volume field sessions
- Vihtavuori lot-to-lot consistency – single-facility Finnish manufacturing; specifically valued in competition where batch changes mid-season require load recalibration
- Short-cut grain metering – better than standard long-stick powders; appropriate for volumetric production loading
Limitations:
- Temperature sensitivity (0.4-0.6 fps/°F) – not at Hodgdon Extreme series levels (~0.3 fps/°F); H4198 provides approximately 50% better seasonal stability
- 7.62x39mm semi-automatic gas system caution – Accurate 1680 is more specifically documented for AK/SKS gas system cycling; N130 is more appropriate for 7.62x39mm bolt-action precision
- 45-70 Government application requires pressure tier awareness – three-tier safety framework applies
- Higher cost per pound than domestic alternatives at comparable burn rates
- Fast burn rate limits application to small-capacity cases and light bullets in medium cases

N130 in the Vihtavuori N100 Fast-Rifle Series
N130 occupies a defined position in the Finnish powder lineup:
| Powder | Grain Size | Density (g/cc) | Burn Rate | Best Application |
|---|---|---|---|---|
| Vihtavuori N120 | 0.8 mm x 0.6 mm | 0.840 | Fastest | 221 Fireball, 222 Rem light, 300 BLK supersonic |
| Vihtavuori N130 | 1.0 mm x 0.6 mm | 0.870 | Reference | 222 Rem standard, 223 Rem light, 204 Ruger |
| Vihtavuori N133 | ~1.2 mm x 0.6 mm | 0.870 | Slower | 222 Rem benchrest, 223 Rem precision |
| Vihtavuori N135 | Similar | ~0.890 | Slower | 223 Rem heavy, 308 Win (light) |
The original article’s description of N130 as “situated between N120 and N133” is correct for the burn rate ordering. N130 and N133 overlap significantly in 222 Remington and 204 Ruger applications, with load development in the specific rifle determining which produces better standard deviations. The difference in burn rate between them is small but measurable.
Temperature Stability – The 0.4-0.6 fps/°F Advantage
0.4-0.6 fps per degree Fahrenheit is the documented performance for N130 – specifically better than double-base ball alternatives and close to Vihtavuori’s claimed figure.
For 222 Remington varmint use across a typical hunting day temperature swing:
| Powder | 60°F Daily Swing | At 300 yards | At 400 yards |
|---|---|---|---|
| Hodgdon H4198 | ~18 fps | <0.4″ | <0.7″ |
| Vihtavuori N120 | ~30-42 fps | ~0.6-0.9″ | ~1-1.5″ |
| Vihtavuori N130 | ~24-36 fps | ~0.5-0.7″ | ~0.9-1.3″ |
| Accurate 2015 | ~27-45 fps | ~0.5-1.0″ | ~1-1.8″ |
| Accurate 1680 | ~60-90 fps | ~1.5-2.0″ | ~2.5-3″ |
At typical varmint distances (0-400 yards), N130’s variation is manageable. For day-long prairie dog sessions, the stability provides meaningful POI consistency compared to double-base ball alternatives.
Burn Rate Comparison and Competing Powders
The comparison table density values from the original article are corrected below:
| Powder | Type | Density (g/cc) | Burn Position | Key Character |
|---|---|---|---|---|
| Hodgdon H4198 | SB Short-Cut | 0.865 | Slightly Slower | Extreme series |
| IMR 4198 | SB Short-Cut | 0.865 | Slightly Slower | Traditional |
| Vihtavuori N130 | SB Short-Cut | 0.870 | Reference | Decoppering |
| Vihtavuori N120 | SB Micro-Stick | 0.840 | Faster | Smaller cases |
| Accurate 2015 | SB Short-Cut | 0.895 | Slightly Slower | Versatile |
| Alliant Reloder 7 | SB Extruded | 0.880 | Slightly Slower | Straight-wall |
| Vihtavuori N133 | SB Short-Cut | 0.870 | Slightly Slower | 222 Rem benchmark |
The original article’s H4198 density (0.835 g/cc) and IMR 4198 density (0.850 g/cc) are corrected to ~0.865 g/cc for both.
vs. Hodgdon H4198: H4198 burns slightly slower with Extreme series stability (~0.3 fps/°F vs N130’s 0.4-0.6 fps/°F). N130 provides the decoppering additive that H4198 lacks and Vihtavuori’s documented lot-to-lot consistency. For year-round competition where the Extreme series stability specifically matters, H4198 provides better seasonal consistency. For shooters who value decoppering and European manufacturing consistency, N130 is competitive.
vs. Vihtavuori N133: N133 burns slightly slower and is the Vihtavuori benchmark for 222 Remington benchrest and 223 Remington precision. N130 is slightly faster – more appropriate for the smaller 221 Fireball and lighter 222 Remington loads. Both carry the decoppering additive and Vihtavuori consistency. Load development in the specific rifle determines which produces lower standard deviations.
vs. Accurate 2015: Accurate 2015 is a domestic single-base short-cut powder at a slightly slower burn rate – more widely stocked and documented in North American manuals. N130 offers the decoppering additive and Vihtavuori consistency. The original article’s claim that Accurate 2015 “generally creates more carbon fouling” is broadly true – N130’s higher-purity Finnish nitrocellulose produces less residue. For a reloader who values decoppering and lot consistency, N130 is the premium alternative. For one who values North American availability and lower cost, Accurate 2015 is the practical choice.
vs. Alliant Reloder 7: Reloder 7 is a single-base extruded powder at a slightly slower burn rate, specifically documented for straight-wall hunting cartridges (45-70 Government, 444 Marlin). N130 is better matched for small-bore bottle-neck benchrest and varmint cases; Reloder 7 has the deeper straight-wall data history.
Recommended Cartridges and Applications
Vihtavuori N130 is most effective in small-capacity bottle-neck rifle cases and as a secondary choice for large-bore straight-wall cases at low-to-moderate pressures.
| Cartridge | Bullet Weight Range | Notes |
|---|---|---|
| 222 Remington | 40-55 gr | Primary precision benchrest and varmint |
| 204 Ruger | 24-40 gr | High-velocity predator control |
| 223 Remington | 40-52 gr | Light varmint bullets only |
| 221 Fireball | 40-52 gr | Maximum velocity small-bore |
| 7.62x39mm | 123-125 gr | Bolt-action precision – see note |
| 6mm PPC | 65-75 gr | Short-range benchrest |
| 22 Hornet | 35-52 gr | Vintage small-bore varmint |
| 45-70 Government | 300-405 gr | Pressure tiers only – see note |
7.62x39mm note: Accurate 1680 is more specifically documented for AK/SKS semi-automatic gas system cycling in 7.62x39mm. N130 is appropriate for 7.62x39mm bolt-action precision use where gas port pressure timing is not a constraint.
45-70 Government pressure tier note: Three distinct pressure tiers apply: Trapdoor (~14,000-20,000 PSI), lever-action (~28,000-40,000 PSI), and modern single-shot (~50,000-60,000 PSI). N130 is documented for the lower pressure tiers. Verify from current Vihtavuori published data for the specific tier matching your rifle.
223 Remington light-bullet note: N130 is appropriate for 223 Remington with 40-52 grain varmint bullets where the smaller effective case volume at these light loads matches the burn rate window. For standard 55-69 grain 223 Remington loads, Vihtavuori N133 or Vihtavuori N135 are better matched.
Bullets
Vihtavuori N130 performs best with light-to-standard weight precision benchrest and varmint bullets in small-bore calibers.

Metering and Equipment Compatibility
Vihtavuori N130’s short-cut geometry (1.0 mm x 0.6 mm) provides substantially better metering than traditional long-stick extruded powders. On quality volumetric equipment like the Redding Competition BR-30 and Redding Competition 10X, ±0.08-0.12 grain variance is achievable.
For precision benchrest single-stage loading: throw under target weight, trickle to exact weight with a Frankford Arsenal Powder Trickler on a RCBS MatchMaster for ±0.02 grain consistency.
The Pro Tip in the original article about targeting 90-95% case fill is sound guidance and applies specifically to fast single-base powders in small cases. Below 90% case fill in 222 Remington and 204 Ruger, combustion consistency decreases and extreme spread increases. Work up to near-maximum charge weights where case fill reaches the optimal range.
Reloading Safety Notes
All charge weights must come from current published Vihtavuori load data for N130 specifically. Vihtavuori publishes free online load data. Do not substitute Hodgdon H4198, IMR 4198, or Vihtavuori N120 charge weights without independent verification.
[45-70 Government] pressure tier matching is mandatory. Verify from Vihtavuori published data for the specific pressure tier.
[7.62x39mm] semi-automatic note: If loading for AK/SKS semi-automatic cycling, Accurate 1680 is the more specifically documented powder for gas port pressure timing. N130 is for bolt-action 7.62x39mm precision only.
Start 10% below the listed maximum and work up in 0.2-grain increments for small benchrest cases. Watch for flattened primers, stiff bolt lift, ejector marks.
See the overpressure in reloading guide for systematic pressure sign identification.
FAQ
What is the difference between N130 and N133 for 222 Remington?
N133 burns slightly slower – it is the Vihtavuori benchmark for 222 Remington benchrest precision. N130 burns slightly faster and is better matched for lighter bullets in 222 Remington and for the smaller 221 Fireball case. In 222 Remington with standard 52-55 grain benchrest bullets, N133 is typically the better starting point. For lighter 40-50 grain loads, N130 may be more appropriate. Load development in the specific rifle determines the final choice.
Is N130 appropriate for 223 Remington standard loads?
For standard 55-62 grain 223 Remington loads, Vihtavuori N133 or Vihtavuori N135 are better matched. N130 is specifically appropriate for 223 Remington with very light 40-52 grain bullets where the effective case volume reduction makes the faster burn rate more efficient.
Conclusion
Vihtavuori N130 delivers the Vihtavuori single-base advantages – decoppering additive, clean burning, and lot-to-lot consistency – at a burn rate specifically suited to small-bore benchrest cases and light-bullet varmint applications. Its position between N120 and N133 fills a defined niche in the Finnish lineup.
Choose Vihtavuori N130 if you load 222 Remington with light 40-50 grain bullets, 204 Ruger, or 221 Fireball where Finnish manufacturing consistency and decoppering chemistry are specifically valued. Choose Vihtavuori N133 if standard-weight 222 Remington benchrest loads with 52-55 grain bullets are the primary application. Choose Hodgdon H4198 if Extreme series temperature stability is the priority in these applications. Choose Accurate 2015 if domestic availability and lower cost at comparable burn rate is the priority.
