Accurate 2230 has long been established as a cornerstone propellant for high-volume shooters and precision reloaders focusing on small-to-medium rifle cartridges. Originally designed as a specialized 223 Remington powder, its versatility has expanded its reach across a broad spectrum of modern cartridges. Accurate 2230 is a fast-burning, double-base spherical powder that offers exceptional versatility, making it a “must-have” on any reloader’s bench.
- Main Application: High-volume reloading for 223 Remington and 308 Winchester.
- Key Advantage: Exceptional metering consistency and high loading density.
- Burn Rate: Fast-intermediate rifle propellant, positioned near Hodgdon H335 and Ramshot X-Terminator.
- What This Guide Covers: Comprehensive technical specifications, a 4-way competitive burn rate analysis, and optimized component pairings including primers and bullets.
Best For: High-volume AR-15 shooters, competitive service rifle marksmen, and varmint hunters requiring consistent volumetric dosing.
Powder Description & Technical Profile
Accurate 2230 is a double-base, spherical (ball) powder known for its high energy density and compact grain structure. Because it is double-base, it contains nitroglycerin, which contributes to higher velocity potentials in short-barreled rifles compared to some single-base alternatives. The physical geometry of the grains is remarkably uniform, appearing as tiny, polished spheres that flow through mechanical measures like water.
The expert “feel” of Accurate 2230 is characterized by a rapid pressure onset that sustains well through the mid-bore. It provides a “sharp push” rather than a “progressive shove,” which is why it excels in smaller capacity cases where efficient combustion in 16-20 inch barrels is required.
Pros
- Superior metering allows for “throw and go” loading without constant weighing.
- Excellent temperature stability for a double-base ball powder.
- High chemical density allows for maximum case fill in compressed loads.
- Extremely versatile across many 22 and 6mm caliber cartridges.
Cons
- Higher flame temperature compared to single-base powders like Vihtavuori N133.
- Can be slightly “dirty” if used in extremely low-pressure applications.
Technical Characteristics
| Property | Specification |
| Manufacturer | Accurate Powders |
| Type | Double-Base Spherical |
| Bulk Density (g/cc) | 0.960-0.990 |
| Grain Shape | Spherical / Ball |
| Coating | Standard Deterrent |
Temperature Stability & Burn Rate Analysis
Accurate 2230 occupies a specific niche in the burn rate hierarchy, sitting just slightly faster than Accurate 2460 and Winchester 748. While spherical powders were historically sensitive to temperature, modern iterations of Accurate 2230 utilize improved deterrent coatings that minimize FPS fluctuations during seasonal changes.
Reloaders can expect an approximate variation of 0.8-1.2 FPS per degree Fahrenheit. While it is not as thermally inert as the Hodgdon Varget “Extreme” series, it remains far more stable than older ball powders.
Stability Table
| Powder | Type | Thermal Sensitivity |
| Accurate 2230 | Double-Base Ball | Moderate-Stable |
| Hodgdon H4895 | Single-Base Extruded | Low (Benchmark) |
| Winchester 748 | Double-Base Ball | Moderate-Sensitive |
Powder Comparison
To understand where Accurate 2230 sits, we must compare it against its closest functional rivals. It is often traded interchangeably with Ramshot X-Terminator, as the two share nearly identical load data in many manuals.
| Powder | Burn Rate | Density | Primary Cartridges |
| Accurate 2200 | Faster | 0.930 | 223 Remington, 6.8 SPC |
| Alliant Reloder 10X | Faster | 0.890 | 222 Remington, 223 Remington |
| Accurate 2230 | Target | 0.975 | 223 Remington, 308 Winchester |
| Hodgdon H335 | Slower | 0.985 | 223 Remington, 308 Winchester |
| Accurate 2460 | Slower | 0.980 | 308 Winchester, 30-06 Springfield |
Performance, Metering & Equipment
Metering is the standout feature of Accurate 2230. Because of its spherical nature, it does not “cut” grains in mechanical measures. Using equipment like the Hornady Lock-N-Load Powder Measure or the Redding Match Grade 3BR Powder Measure, reloaders can frequently achieve charge-to-charge consistencies within 0.1 grains.
For those using automated systems like the RCBS MatchMaster Digital Powder Scale & Dispenser, the powder flows exceptionally fast, reducing the “trickle time” significantly. Fouling is manageable; however, as with all high-energy ball powders, a proper cleaning regimen is recommended to prevent carbon ring formation in the throat.
Recommended Cartridges and Applications
Accurate 2230 is perhaps most famous for its performance in the 223 Remington, but its utility extends to many short-action rifle cartridges.
| Cartridge | Primary Application |
| 223 Remington | Service Rifle & High-Volume Plinking |
| 308 Winchester | Light Bullet (110-150 grain) Hunting/Tactical |
| 204 Ruger | Varmint Control |
| 6mm ARC | Gas Gun Precision |
| 222 Remington | Small Game Hunting |
| 7.62x39mm | Modern Sporting Rifle Performance |
| 30-30 Winchester | Lever Action Hunting |
Bullets
Accurate 2230 performs best with light-to-medium weight bullets within their respective calibers. In 223 Remington, it is legendary with 55-grain projectiles.
| Bullet Brand | Model | Weight Range (Grains) |
| Hornady | Hornady V-Max Bullet | 40-55 |
| Sierra | Sierra MatchKing Bullet | 52-69 |
| Nosler | Nosler Ballistic Tip Bullet | 40-60 |
| Barnes | Barnes TSX Bullet | 50-62 |
| Speer | Speer TNT Bullet | 50-55 |
| Berger | Berger Target Bullet | 52-68 |
Primers
Because Accurate 2230 is a double-base spherical powder, it can sometimes benefit from a magnum primer to ensure consistent ignition, especially in cold weather or when using higher-density loads.
- CCI 400 – Small Rifle (Standard)
- CCI 450 – Small Rifle Magnum (Recommended for Ball Powder)
- Federal 205 – Small Rifle (Precision)
- Winchester WSR – Small Rifle
- Remington 7-1-2 – Small Rifle Bench Rest
- CCI No. 41 – Small Rifle (Military / 5.56 NATO)
- Sellier-Bellot V361607 – Small Rifle
- Fiocchi Small Rifle – Standard Small Rifle
- RWS 4033 – Small Rifle (International)
- Ginex Small Rifle – Small Rifle
Conclusion & Expert Verdict
Accurate 2230 remains one of the most practical choices for the modern reloader. While it may not offer the extreme temperature immunity of specialized competition powders, its ability to meter flawlessly through a mechanical measure makes it the superior choice for high-volume production. Whether you are loading 1,000 rounds for a weekend carbine course or crafting precise varmint loads for 223 Remington, Accurate 2230 delivers a balanced performance profile that is hard to beat.
Expert Pro Tip: When loading Accurate 2230 in high-capacity 223 Remington cases with heavy bullets, use a CCI No. 41 primer. The thicker cup and increased brisance help maintain consistent ignition and prevent “slam-fires” in semi-automatic platforms while reliably lighting off the high-density ball powder charge.
