Accurate 2230 has been a staple on reloading benches for decades, and for good reason. It is a fast-to-intermediate burning, double-base spherical powder built around the needs of high-volume AR shooters and service rifle competitors – but it earns its place in any serious reloader’s cabinet well beyond that narrow description. If you load 223 Remington in any meaningful quantity, Accurate 2230 belongs in your burn rate lineup. It meters like a liquid, fills cases cleanly, and produces consistent velocities across a wide range of bullet weights.
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. If you have loaded Accurate 2230 in practice – leave a comment below: real-world experience from the reloading bench is what separates verified data from manufacturer claims.
Powder Description and Technical Profile
Accurate 2230 is a double-base, spherical powder, meaning it contains both nitrocellulose and nitroglycerin as energy sources. The nitroglycerin component pushes energy density higher than single-base alternatives, which translates to real velocity gains in short-barreled rifles. A 16-inch AR-15 extracts noticeably more performance from 2230 than it would from a comparable single-base powder at similar charge weights.
The grain geometry is the practical heart of this powder’s appeal. Each grain is a nearly perfect sphere, uniformly sized and smooth-coated with a deterrent compound that moderates the burn rate and reduces sensitivity to temperature swings. Because there are no extruded sticks to bridge, shear, or pack unevenly, the powder flows through a mechanical measure the way a liquid would. Charge-to-charge consistency is simply not something most reloaders struggle with when using 2230 – the spherical geometry handles that problem before it starts.
Burn behavior is best described as a sharp, fast pressure onset that sustains well through the mid-bore and clears cleanly before the bullet exits a 20-inch barrel. This is why the powder works so efficiently in the 18-20 inch service rifle range. It does not suit long-barreled magnums or cartridges that need a slower, more progressive burn curve. Its place in the burn rate chart sits just slightly faster than Hodgdon H335 and Accurate 2460, and meaningfully slower than Accurate 2200.
Strengths:
- Exceptional metering consistency (±0.04-0.07 grains) – a mechanical measure set at a given charge weight stays there, session after session
- High bulk density (0.960-0.990 g/cc) means good case fill without compressed charges in 223 Remington with standard bullet weights
- Versatile across 22-caliber and 6mm cartridges in the short-action range
- Reasonable temperature stability for a double-base ball powder – approximately 0.8-1.2 fps/°F
Limitations:
- Higher flame temperature than single-base alternatives like Vihtavuori N133 – slightly accelerated throat erosion in high-volume barrels
- Runs dirtier at the low end of the pressure curve – loading well below minimum charges produces more residue
- Not suited for temperature-critical long-range competition where Hodgdon Varget or IMR 4166 Enduron provide more consistent seasonal nodes
Technical Characteristics
| Property | Specification |
|---|---|
| Manufacturer | Accurate Powders (Western Powders) |
| Type | Double-Base Spherical |
| Bulk Density (g/cc) | 0.960 – 0.990 |
| Grain Shape | Spherical / Ball |
| Coating | Standard Deterrent |
| Burn Rate Position | Fast-Intermediate Rifle |
| Temperature Sensitivity | ~0.8-1.2 fps / °F |
Temperature Stability
Expect roughly 0.8-1.2 fps per degree Fahrenheit of velocity shift – more than a true temperature-insensitive Extreme series powder, but far less than older-generation ball powders.
| Powder | Type | Thermal Sensitivity |
|---|---|---|
| Accurate 2230 | Double-Base Ball | ~0.8-1.2 fps/°F |
| Hodgdon H4895 | Single-Base Extruded | ~0.3 fps/°F (Extreme) |
| Hodgdon Varget | Single-Base Short-Cut | ~<0.5 fps/°F (Extreme) |
| Hodgdon H335 | Double-Base Ball | ~1.0-1.5 fps/°F |
| Winchester 748 | Double-Base Ball | ~1.5-2.0 fps/°F |
For varmint hunting at known distances or high-volume carbine training, 0.8-1.2 fps/°F is entirely workable. For precision long-range competition at 800-1,000 yards across seasons, a temperature-stabilized line is more appropriate.
Powder Comparison
Accurate 2230 often trades places with Ramshot X-Terminator in published load data – the two share nearly identical density and burn rate profiles. If you cannot source one, the other is a realistic starting point, but always verify against current published data and work up from the starting charge.
| Powder | Burn Rate | Density (g/cc) | Primary Cartridges |
|---|---|---|---|
| Accurate 2200 | Faster | 0.930 | 223 Rem, 6.8 SPC |
| Alliant Reloder 10X | Faster | 0.890 | 222 Rem, 223 Rem |
| Accurate 2230 | Reference | 0.975 | 223 Rem, 308 Win (light) |
| Hodgdon H335 | Slightly Slower | 0.985 | 223 Rem, 5.56 NATO |
| Accurate 2460 | Slower | 0.980 | 308 Win, 30-06 Springfield |
| Ramshot X-Terminator | Similar | ~0.975 | 223 Rem, 6mm PPC |
| Accurate 2015 | Slightly Faster | 0.895 | 222 Rem, 223 Rem |
vs. Hodgdon H335: H335 meters nearly as well and occupies the same burn rate neighborhood. Accurate 2230 tends to produce slightly higher velocities at comparable charges and fills cases a touch more efficiently. Neither is categorically better – it comes down to availability and which produces better standard deviations in the specific barrel.
vs. Hodgdon Varget: Varget is Extreme series single-base at ~<0.5 fps/°F – approximately 2-3x more seasonally stable. Better matched for 223 Remington with 69-80 grain match bullets and 308 Winchester standard loads. Accurate 2230 meters better and is better matched for 50-62 grain varmint production.
vs. Accurate 2015: Accurate 2015 is single-base short-cut at a slightly faster burn rate – better temperature stability from single-base chemistry, less metering efficiency from extruded geometry. For precision varmint work where single-base cleanliness and modest stability improvement matter, Accurate 2015 is appropriate. For volume production, Accurate 2230 is more efficient.
vs. Vihtavuori N133: N133 produces less carbon residue and has better throat longevity from its single-base chemistry. Accurate 2230 meters better and produces slightly higher velocities. For benchrest cleanliness and barrel life, N133 is the cleaner choice. For high-volume production, Accurate 2230 is the practical choice.
Recommended Cartridges and Applications
| Cartridge | Bullet Weight Range | Notes |
|---|---|---|
| 223 Remington | 50-62 gr | Primary application – classic sweet spot |
| 204 Ruger | 32-40 gr | Varmint maximum velocity |
| 222 Remington | 50-55 gr | Classic small-bore varmint |
| 6mm ARC | 90-108 gr | Gas gun precision – verify data |
| 7.62x39mm | 123-125 gr | Modern sporting rifle bolt-action |
| 308 Winchester | 110-150 gr | Light bullets only – see note |
| 30-30 Winchester | 110-150 gr | Light bullets only – verify data |
308 Winchester light-bullet note: appropriate only for 110-150 grain bullets where effective case volume decreases toward the small-case burn rate window. With standard 168-175 grain match bullets, the burn rate is too fast – pressures climb quickly with limited velocity return. Use Hodgdon Varget, Accurate 2520, or IMR 4895 for standard 308 Winchester loads.

Primers
| Primer | Type | Application |
|---|---|---|
| CCI No. 41 | Small Rifle Magnum (Mil-Spec) | Required for AR-15 / 5.56 NATO semi-auto |
| CCI 450 | Small Rifle Magnum | Cold weather below 20°F, dense charges |
| Federal GM205M | Small Rifle Match | Competition precision |
| CCI BR-4 | Small Rifle Benchrest | Precision bolt-action competition |
| CCI 400 | Small Rifle Standard | General 223 Rem, moderate temps |
| Federal 205 | Small Rifle Standard | Precision loads, bolt guns |
| Winchester WSR | Small Rifle Standard | General use |
| Remington 7-1/2 | Small Rifle Bench Rest | Precision bolt-gun applications |
| Fiocchi Small Rifle | Small Rifle Standard | Volume production alternative |
| RWS 4033 | Small Rifle | Premium European precision |
| Ginex Small Rifle | Small Rifle Standard | Cost-effective general use |
| Sellier & Bellot V360247 | Small Rifle Standard | Consistent international option |
For AR-15 / 5.56 NATO semi-automatic platforms, the CCI No. 41 mil-spec cup primer is required. Dense ball powder charges in semi-automatic platforms carry slam-fire risk with standard primer cups.
Always verify primer choice against published data. When switching primer brands, back off 3-5% from the listed starting charge and work up.
Metering and Equipment Compatibility
The metering performance of Accurate 2230 is its most talked-about characteristic. A well-adjusted volumetric measure – whether a Hornady Lock-N-Load Bench Rest Powder Measure, a Redding Match Grade 3BR, or a Lyman Brass Smith Powder Measure – will deliver within 0.1 grains charge-to-charge. For those running automated dispensers like the RCBS MatchMaster or the Hornady Auto-Charge Pro, 2230 runs fast through the trickler because the spherical grains flow freely.
For high-volume AR-15 production on a Dillon XL 750 or Hornady Lock-N-Load AP, the Dillon Precision Case Activated Powder Measure Assembly handles Accurate 2230 with near-liquid consistency at normal cycling speeds.
Reloading Safety Notes
All charge weights should come from current published Accurate / Western Powders data. Start 10% below the listed maximum and work up in 0.3-grain increments, watching for pressure signs: flattened or cratered primers, stiff bolt lift, ejector marks on case heads.
See the overpressure in reloading guide for systematic pressure sign identification.
Conclusion
Accurate 2230 has earned its place through practical merit. It is not the most temperature-stable powder, not the cleanest-burning, and not the ideal choice for heavy bullets or long-range competition. What it is, reliably and consistently, is the easiest high-volume rifle powder to work with at the bench.
Choose Accurate 2230 if you load 223 Remington at volume and want ball powder metering efficiency with competitive velocity. Choose Hodgdon Varget if temperature-insensitive performance for serious long-range competition is the priority. Choose Hodgdon H335 if military 5.56 NATO heritage documentation is specifically needed. Choose Vihtavuori N133 if throat longevity in sustained high-volume use and single-base cleanliness are the priorities. Choose Alliant Reloder 15 if higher velocity with somewhat better temperature stability in 22-250 Remington and 223 Remington match applications is the priority.
