Accurate 2460 is a medium-fast-burning, double-base spherical powder from Western Powders, positioned between Accurate 2230 (faster) and Accurate 2520 (slower) in the Accurate ball powder lineup. It was engineered as a slightly slower variant of Accurate 2230 to cover the application where 2230’s faster burn rate is slightly past optimal – specifically 223 Remington with heavier 62-77 grain match and hunting bullets, and 308 Winchester standard service rifle loads.
The powder’s defining practical properties are the same ones that define the Accurate ball powder lineup generally: ball geometry metering consistency (±0.04-0.07 grains on quality equipment), high bulk density (0.980 g/cc) producing excellent case fill without compressed charges, and double-base energy density providing competitive velocity. What differentiates it from 2230 is the slightly slower burn rate that is more appropriate for the heavier end of 223 Remington bullet weights and for 308 Winchester where 2230 peaks pressure too early.

Powder Description and Technical Profile
Accurate 2460 is a double-base, spherical powder. The double-base chemistry – nitrocellulose plus nitroglycerin – provides the energy density that pushes 223 Remington 69-77 grain match bullets to competitive velocities and 308 Winchester 150-168 grain service rifle bullets to gas-system-appropriate velocities.
The spherical geometry is the practical metering advantage. Very small, uniform spheres roll over each other through measure drums without bridging or shearing, producing charge-to-charge variance of ±0.04-0.07 grains on quality progressive equipment.
Bulk density is 0.980 g/cc – very high for a medium-fast rifle powder. In 223 Remington with 69-77 grain match bullets at working charge weights, case fill runs 90-97%, producing the consistent ignition and low position sensitivity that precision 223 Remington work requires.
The slightly more progressive burn rate compared to Accurate 2230 is the functional differentiator. In 223 Remington with the heavier 69-77 grain bullets that are now common in NRL22, Precision Rifle Series, and service rifle competition, the slower burn rate of Accurate 2460 provides more efficient pressure development than 2230, which can peak too early with these heavier bullets.
Strengths:
- Ball geometry metering (±0.04-0.07 grains) – enables high-volume progressive press production; superior metering to any extruded alternative at this burn rate
- High bulk density (0.980 g/cc) produces excellent case fill in 223 Remington heavy-bullet and 308 Winchester service rifle loads
- Specifically matched burn rate for 223 Remington with 62-77 grain heavy bullets – the application where Accurate 2230 is slightly too fast
- Semi-automatic gas system documentation for M1A/AR-10 cycling in 308 Winchester
- Clean burning at operating pressures – minimal residue at near-maximum loads; dirtier at sub-optimal light charges
Limitations:
- Temperature sensitivity of ~1.0-1.3 fps/°F – standard double-base ball powder behavior; substantially more sensitive than Hodgdon Varget or Hodgdon H4895 Extreme series alternatives
- 204 Ruger application is marginal – the burn rate may be slightly slow for standard 32-40 grain 204 Ruger applications; Hodgdon Benchmark or Hodgdon H322 are better matched. Verify from current published data
- 30-06 Springfield “soft loads” with 110-125 grain bullets is a marginal application – the burn rate is too fast for efficient combustion with standard 150-180 grain 30-06 Springfield hunting loads; this application is only for very light bullets
- Higher flame temperature than single-base alternatives produces slightly more throat erosion in high-volume rapid-fire strings
Technical Characteristics

Burn Rate Positioning
| Powder | Type | Density (g/cc) | Position | Key Application |
|---|---|---|---|---|
| Accurate 2230 | DB Ball | 0.975 | Faster | 223 Rem 50-62 gr, high volume |
| Hodgdon H335 | DB Ball | 0.980 | Slightly Faster | 223 Rem 5.56 heritage |
| Accurate 2460 | DB Ball | 0.980 | Reference | 223 Rem heavy, 308 Win service |
| Accurate 2520 | DB Ball | 0.975 | Slightly Slower | 308 Win Camp Perry |
| Hodgdon BL-C(2) | DB Ball | 0.990 | Slightly Slower | 308 Win 7.62 NATO heritage |
| Alliant Reloder 15 | DB Extruded | 0.920 | Similar | 308 Win, 6.5 CM, higher velocity |
| Hodgdon Varget | SB Short-Cut | 0.910 | Slower | 308 Win Extreme stability |
The original article’s comparison table shows Alliant Reloder 15 density as 0.910 g/cc – this is incorrect. Reloder 15 density is approximately 0.920 g/cc. Both are lower than Accurate 2460’s 0.980 g/cc, meaning the ball powder produces substantially higher case fill per grain of charge.
The key positioning insight: Accurate 2460 occupies the specific burn rate position that serves 223 Remington at the 62-77 grain heavy-bullet end and 308 Winchester at service rifle pressures. This is the overlap zone between the two most popular North American rifle calibers, which explains the powder’s versatility.
Temperature Stability – Practical Assessment
1.0-1.3 fps per degree Fahrenheit is standard double-base ball powder behavior – better than older-generation ball powders but not at Extreme or Enduron levels.
For 308 Winchester service rifle competition across a season:
| Powder | 60°F Swing | At 300 yards | At 600 yards |
|---|---|---|---|
| Hodgdon Varget | ~25-30 fps | <0.5″ | ~1″ |
| Hodgdon H4895 | ~18 fps | <0.5″ | <1″ |
| Accurate 2460 | ~60-78 fps | ~1.5″ | ~2.5″ |
| Accurate 2520 | ~48-72 fps | ~1″ | ~2″ |
| Alliant Reloder 15 | ~60-75 fps | ~1.5″ | ~2.5″ |
For service rifle competition across a season, Accurate 2460 requires seasonal load verification or temperature-corrected firing solutions at 600 yards. For practical hunting at 0-400 yards, the variation is within the ethical shooting margin with a current-season zero.
Burn Rate Comparison and Competing Powders
vs. Accurate 2230: 2230 burns slightly faster and is the correct choice for 223 Remington with standard 50-62 grain varmint and FMJ bullets. Accurate 2460 is better matched when bullet weight increases toward 62-77 grain match projectiles where 2230’s faster burn is slightly inefficient. Both are Western Powders ball powder siblings – same metering efficiency, different burn rate positions.
vs. Hodgdon Varget: Varget is Extreme series single-base at ~<0.5 fps/°F – approximately 2-3x more seasonally stable. It meters adequately from short-cut geometry and is the benchmark for 223 Remington with 69-80 grain precision loads and 308 Winchester bolt-action precision. Accurate 2460 meters better from ball geometry for progressive press production and provides higher velocity from double-base energy. The choice follows the same logic as all standard-vs-Extreme comparisons: production efficiency favors 2460; year-round seasonal consistency favors Varget.
vs. Accurate 2520: Accurate 2520 burns slightly slower – the Camp Perry service rifle powder for 308 Winchester with 168-175 grain match bullets. Accurate 2460 is slightly faster and better matched for 223 Remington heavy-bullet loads. For 308 Winchester with standard 150-168 grain service rifle bullets, both are documented choices; load development in the specific rifle guides the selection.
vs. Alliant Reloder 15: Alliant Reloder 15 is a double-base extruded powder at a comparable burn rate – lower density (0.920 g/cc), slightly better temperature stability than Accurate 2460, and higher velocity from its energy content. Accurate 2460 meters better from ball geometry for progressive press use. For precision single-stage loading where both are weighed and metering variance is eliminated, Reloder 15 is a velocity-priority alternative. For high-volume production, Accurate 2460’s ball geometry is the practical advantage.
vs. Hodgdon BL-C(2): BL-C(2) burns slightly slower with 7.62 NATO heritage specifically for 308 Winchester service rifle cycling. Both are ball powders with comparable metering efficiency. Accurate 2460 is more specifically appropriate for 223 Remington heavy-bullet applications where BL-C(2) is slightly too slow; BL-C(2) has the deeper military heritage documentation for 308 Winchester service rifle use.
Recommended Cartridges and Applications
Accurate 2460 is most effective in small-to-medium capacity cases with standard-to-heavy-for-caliber bullet weights where the burn rate covers the heavy end of 223 Remington and the standard range of 308 Winchester.
| Cartridge | Bullet Weight Range | Notes |
|---|---|---|
| 223 Remington | 62-77 gr | Primary – heavy match bullets |
| 308 Winchester | 150-168 gr | Service rifle and hunting |
| 6mm ARC | 90-108 gr | Gas gun precision |
| 6.5 Grendel | 100-123 gr | Intermediate hunting |
| 22-250 Remington | 50-60 gr | Mid-weight varmint |
| 30-06 Springfield | 110-150 gr | Light bullets only – see note |
| 204 Ruger | 32-40 gr | Verify data – may be too slow |
223 Remington with 62-77 grain heavy match bullets is the most specifically useful application for Accurate 2460. Where Accurate 2230 is the optimal choice for 50-62 grain standard 223 Remington loads, Accurate 2460 fills the heavier-bullet gap – providing better pressure development with 69-77 grain Hornady ELD-M, Sierra MatchKing 77 grain, and similar projectiles that have become the standard for NRL22 and longer-range precision rifle applications in this caliber.
308 Winchester with 150-168 grain bullets is the service rifle application. For M14/M1A and AR-10 gas systems, use CCI No. 34 mil-spec primers to prevent slam-fire.
30-06 Springfield note: The original article lists 30-06 Springfield as an application for “light bullet (110-125 grain) soft loads.” This is a narrow edge application – the burn rate is appropriate only for very light bullets where effective case volume reduction brings the burn rate window closer to Accurate 2460’s position. For standard 150-180 grain 30-06 Springfield hunting loads, slower powders like Hodgdon H4350 or IMR 4350 are better matched. Verify from current Western Powders published data.
204 Ruger note: Hodgdon Benchmark and Hodgdon H322 are the more specifically documented choices for 204 Ruger at standard 32-40 grain bullet weights. Accurate 2460’s burn rate may be slightly slow for optimal 204 Ruger combustion efficiency. Verify from current Western Powders published data before loading.

Primers
Accurate 2460 as a double-base ball powder responds well to standard and magnum small rifle primers in 223 Remington applications and standard large rifle primers for 308 Winchester bolt-action use.
For AR-15 semi-automatic 223 Remington platforms, CCI No. 41 mil-spec cup primer is required to prevent slam-fire from the free-floating firing pin. For M14/M1A and AR-10 308 Winchester platforms, CCI No. 34 large rifle mil-spec primer is required.
| Primer | Type | Application |
|---|---|---|
| CCI No. 41 | Small Rifle Magnum (Mil-Spec) | Required for AR-15 semi-auto |
| CCI 450 | Small Rifle Magnum | Maximum ignition consistency |
| Federal GM205MAR | Small Rifle Match (AR) | Competition AR-15 precision |

Metering and Equipment Compatibility
Accurate 2460’s ball geometry delivers the metering performance that defines the Accurate ball powder lineup. On a Dillon XL 750, Dillon RL 1100, or Hornady Lock-N-Load AP, charge-to-charge variance under 0.07 grains is achievable at normal cycling speeds – enabling high-volume match ammunition production without overhead.
The Pro Tip in the original article about targeting 90-95% case fill is sound practical guidance. With Accurate 2460’s high density (0.980 g/cc), working charge weights in 223 Remington and 308 Winchester naturally fall in the 90-97% case fill range, which correlates with the most consistent standard deviations and lowest extreme spread.
For precision single-stage loading, auto-dispensers including the RCBS MatchMaster and Frankford Arsenal Intellidropper 2.0 handle the fine spheres efficiently.
Reloading Safety Notes
All charge weights must come from current published Western Powders / Accurate load data for Accurate 2460 specifically. Do not substitute Accurate 2230, Hodgdon H335, or Accurate 2520 charge weights without independent verification.
Semi-automatic platform primer requirements:
- AR-15 (223 Remington): CCI No. 41 mil-spec small rifle primer
- M14/M1A/AR-10 (308 Winchester): CCI No. 34 mil-spec large rifle primer
Temperature protocol: develop maximum charges at the highest expected firing temperature. At 1.0-1.3 fps/°F, summer heat can push near-maximum loads toward elevated pressure.
Start 10% below the listed maximum and work up in 0.2-0.3 grain increments for 223 Remington and 0.3 grain increments for 308 Winchester.
See the overpressure in reloading guide for systematic pressure sign identification.
FAQ
What separates Accurate 2460 from Accurate 2230?
Burn rate – Accurate 2460 burns slightly slower. The practical consequence: Accurate 2230 is better matched for 223 Remington with standard 50-62 grain bullets; Accurate 2460 is better matched for 223 Remington with heavy 62-77 grain match bullets and for 308 Winchester service rifle loads where 2230 peaks pressure too early. Both are ball powders with identical metering performance.
Is Accurate 2460 appropriate for 308 Winchester precision bolt-action competition?
It produces accurate bolt-action 308 Winchester loads and is documented for competition use. The temperature sensitivity (1.0-1.3 fps/°F) is the limitation for year-round competition where seasonal zero consistency without recalibration is essential. Hodgdon Varget is the more seasonally stable choice for that application.
Can Accurate 2460 be used in 308 Winchester service rifle semi-automatic platforms?
Yes – Accurate 2460 is documented for 308 Winchester in gas-operated M1A/AR-10 platforms. Use CCI No. 34 mil-spec primer for all semi-automatic large-rifle platforms to prevent slam-fire from the floating firing pin.
