Accurate 2460 is a highly versatile, double-base spherical propellant that has earned a reputation as a “workhorse” for intermediate rifle cartridges. Originally developed as a slightly slower-burning variant of the legendary Accurate 2230, this powder was engineered to provide optimal pressure curves for cartridges requiring a slightly higher gas volume. Accurate 2460 excels in both bolt-action and semi-automatic platforms, offering the perfect balance of high energy density and impeccable physical consistency.
For the reloader seeking a single powder capable of fueling everything from high-volume 223 Remington loads to heavy-bullet 308 Winchester match rounds, Accurate 2460 stands as a premier candidate. Its spherical geometry ensures that it flows through measures with liquid-like precision, making it an ideal choice for progressive reloading setups where speed and accuracy are equally prioritized.

Powder Description & Technical Profile
Accurate 2460 is a double-base propellant, meaning it incorporates nitroglycerin alongside nitrocellulose to increase its energy content per unit of weight. Physically, it is a “ball” or spherical powder, characterized by very small, uniform grains that are polished and treated with deterrent coatings. This physical form is the secret behind its legendary metering; the grains act like tiny ball bearings, rolling over one another without the “crunching” or “bridging” often associated with extruded (stick) powders.
The expert “feel” of Accurate 2460 is one of controlled, sustained energy. While it is fast enough to perform well in shorter 16-18 inch barrels common in modern sporting rifles, it has a slightly more progressive burn rate than Accurate 2230, allowing it to push heavier bullets to competitive velocities without reaching dangerous pressure ceilings prematurely. In cartridges like the 308 Winchester, it provides a consistent pressure wave that is particularly well-suited for the gas ports of M1A and AR-10 platforms.
Pros
- Perfect volumetric metering through mechanical and digital measures.
- High energy density allows for excellent case fill, often preventing “powder rattle” in partially filled cases.
- Extremely versatile across a wide range of calibers from 204 Ruger to 30-06 Springfield.
- Excellent performance in semi-automatic gas systems.
Cons
- Double-base composition leads to higher flame temperatures, which can accelerate throat erosion in high-volume “mag-dump” scenarios.
- Slightly more sensitive to extreme temperature swings than high-end single-base extruded powders.
Technical Characteristics
The technical profile of Accurate 2460 highlights its role as a dense, high-energy propellant. Its bulk density is notably high, which is a hallmark of the Accurate spherical line, allowing reloaders to fit more weight into the available internal case volume.
| Property | Specification |
| Manufacturer | Accurate Powders |
| Type | Double-Base Spherical |
| Bulk Density (g/cc) | 0.980 |
| Grain Shape | Spherical / Ball |
| Coating | Standard Graphite/Deterrent |
Temperature Stability & Burn Rate Analysis
In the hierarchy of burn rates, Accurate 2460 sits in the “sweet spot” for small-to-medium rifle cartridges. It is slower than Accurate 2230 but faster than the “M14/M1A” classic Accurate 2520. This positioning makes it particularly effective for 223 Remington shooters who have moved from 55 grain bullets to 62-77 grain match projectiles.
Regarding temperature stability, Accurate 2460 is a modern spherical powder. While it does not carry a specific “Extreme” or “Enduron” branding, its deterrent coatings are designed to minimize the pressure spikes associated with hot summer range days. Reloaders typically see a velocity shift of approximately 1.0-1.3 FPS per degree Fahrenheit. While it may not match the extreme stability of Hodgdon Varget, it is significantly more consistent than older ball powder formulations.
Stability Table
| Powder | Type | Thermal Sensitivity |
| Accurate 2460 | Double-Base Ball | Moderate |
| Hodgdon Varget | Single-Base Extruded | Low (Benchmark) |
| Winchester 748 | Double-Base Ball | Moderate-Sensitive |
Powder Comparison
To understand the utility of Accurate 2460, it is helpful to compare it against its closest competitors in the medium-fast rifle category.
| Powder | Burn Rate | Density | Primary Cartridges |
| Accurate 2230 | Faster | 0.975 | 223 Remington, 308 Winchester |
| Hodgdon H335 | Faster | 0.985 | 223 Remington, 308 Winchester |
| Accurate 2460 | Target | 0.980 | 223 Remington, 308 Winchester |
| Accurate 2520 | Slower | 0.990 | 308 Winchester, 6mm ARC |
| Alliant Reloder 15 | Slower | 0.910 | 308 Winchester, 223 Remington |
Performance, Metering & Equipment
One of the primary reasons reloaders choose Accurate 2460 is its behavior in reloading equipment. If you are using a progressive press like the Dillon XL 750 or the Hornady Lock-N-Load AP, you will find that Accurate 2460 drops with incredible consistency, often showing zero variation on a digital scale.
For precision-minded reloaders using a RCBS MatchMaster Digital Powder Scale & Dispenser or a Frankford Arsenal Intellidropper 2.0, the spherical grains allow for rapid-fire dispensing without the “over-throws” that frequently occur with long-cut stick powders.
When it comes to fouling, Accurate 2460 burns cleanly at near-maximum pressures. Like many double-base spherical powders, if the load is too light, you may see some “sooting” on the case necks. However, when pushed into its optimal pressure window, it leaves minimal residue.
Recommended Cartridges and Applications
While Accurate 2460 is versatile, it has several “star” applications where it outperforms almost everything else in its class.
| Cartridge | Primary Application |
| 223 Remington | Heavy Bullet (69-77 grain) Match Loads |
| 308 Winchester | Standard 150-168 grain Tactical/Hunting |
| 204 Ruger | Long-Range Varmint |
| 6mm ARC | Medium Bullet Gas Gun Optimization |
| 22-250 Remington | High-Velocity Varmint |
| 30-06 Springfield | Light Bullet (110-125 grain) “Soft” Loads |
| 6.5 Grendel | Intermediate Hunting Applications |
Bullets
Accurate 2460 is at its best when paired with medium-to-heavy bullets for a given caliber, as the slightly slower burn rate provides the necessary “push” for these projectiles.
| Bullet Brand | Model | Weight Range (Grains) |
| Hornady | Hornady ELD-M Bullet | 73-75 (223 Rem), 168 (308 Win) |
| Sierra | Sierra MatchKing Bullet | 69-77 (223 Rem), 155-168 (308 Win) |
| Nosler | Nosler Custom Competition Bullet | 69-77 (223 Rem), 168 (308 Win) |
| Barnes | Barnes TTSX Bullet | 55-62 (223 Rem), 130-150 (308 Win) |
| Berger | Berger Hybrid Target Bullet | 73-77 (223 Rem), 155-168 (308 Win) |
| Lapua | Lapua Scenar Bullet | 69-77 (223 Rem), 155-167 (308 Win) |
Primers
For spherical powders like Accurate 2460, consistent ignition is the key to minimizing velocity spreads. Many professional reloaders prefer a “Hot” or Magnum primer to ensure the deterrent coatings are fully ignited, especially in larger cases or cold weather.
- CCI 450 – Small Rifle Magnum (Highly Recommended)
- CCI No. 41 – Small Rifle Military (Perfect for AR-15)
- Federal GM205MAR – Small Rifle AR Match
- CCI BR-4 – Small Rifle Bench Rest
- Winchester WSR – Small Rifle
- CCI 200 – Large Rifle (For 308 Winchester)
- Federal 210 – Large Rifle
- RWS 4033 – Small Rifle
- Sellier-Bellot V361607 – Small Rifle
- Remington 7-1-2 – Small Rifle Bench Rest
Conclusion & Expert Verdict
Accurate 2460 remains one of the most logically sound choices for any reloader who values efficiency and physical consistency. Its ability to mirror the burn rate of popular extruded powders while providing the effortless metering of a ball powder makes it a unique asset on the loading bench. While competition-specific powders might offer a slight edge in extreme temperature resistance, Accurate 2460 provides the velocity and accuracy required for 95% of shooting applications – from high-volume tactical training to precision varminting. If your goal is to spend less time fighting your powder measure and more time on the trigger, this is your propellant.
Expert Pro Tip: When using Accurate 2460 for the first time in a new 308 Winchester or 223 Remington load, focus on finding the “pressure node” where your vertical stringing is minimized. Because this powder has such high density, you may find that slightly higher case fill (near 90-95%) yields much better Standard Deviation (SD) numbers than lighter charges. Always use a high-quality primer like the CCI 450 to punch through the deterrent coating for the most consistent long-range performance.
