Accurate 2700 is a medium-slow-burning, double-base spherical powder from Western Powders, positioned in the burn rate class where standard long-action hunting cartridges operate most efficiently: 30-06 Springfield with 150-180 grain bullets, 270 Winchester with 130-150 grain standard loads, and the adjacent calibers that share this case capacity range.
The powder’s defining practical characteristic is ball geometry metering combined with high bulk density (0.975 g/cc) – a combination that makes high-volume hunting ammunition production on progressive equipment practical without the charge-weight overhead that extruded alternatives require. For a hunter loading 200 rounds of 30-06 Springfield annually without a precision auto-dispenser, the ability to produce ±0.1 grain consistency from a standard powder measure is the specific reason to choose Accurate 2700 over the extruded alternatives in the same burn rate class.
The honest context: Accurate 2700 is a standard double-base ball powder without Extreme series or Enduron temperature-stabilizing additives. At 1.2-1.5 fps/°F, it is substantially more thermally sensitive than Hodgdon H4350 (~0.3 fps/°F Extreme series) or IMR 4451 Enduron (<0.15 fps/100°F). For hunting at practical ranges with seasonal load verification, this is manageable. For year-round precision competition where zero consistency across seasons is required, the Extreme and Enduron alternatives are more appropriate.
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 2700 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 2700 is a double-base, spherical powder manufactured for Western Powders (Accurate). The double-base chemistry – nitrocellulose plus nitroglycerin – provides the energy density per grain that allows competitive velocities in medium-large capacity cases like 30-06 Springfield and 270 Winchester from charge weights that fully fill the case without compressed loads.
The spherical geometry is the dominant practical advantage. Ball powders pack uniformly into measure drums at any cycling speed, producing charge-to-charge variance of 0.05-0.1 grains on quality equipment. The original article’s claim of “within a tenth of a grain” is accurate as a practical field description.
Bulk density is approximately 0.975 g/cc – among the highest in the medium-slow rifle class. The original article’s range of “0.965-0.990 g/cc” reflects realistic lot-to-lot variation. At 0.975 g/cc, Accurate 2700 produces significantly higher case fill per grain than lower-density extruded alternatives (IMR 4350 at 0.860 g/cc, Hodgdon H4350 at 0.860 g/cc). In 30-06 Springfield at working charge weights, case fill runs 90-97% – adequate for consistent ignition and minimal position sensitivity.
The “sustained push” pressure curve described in the original article is accurate for double-base ball powders – they tend to produce a broader, more progressive burn profile than sharp-peaking single-base extruded alternatives. This is specifically beneficial for brass life in repeated-fire applications.
Strengths:
- Ball geometry metering (0.05-0.1 grain variance) – the primary practical advantage for high-volume production loading
- High bulk density (0.975 g/cc) – produces excellent case fill in standard long-action cases without compression
- Double-base energy density – competitive velocities in 30-06 Springfield and 270 Winchester at appropriate pressures
- Versatile application range across standard long-action cartridges
- Progressive “push” pressure curve – beneficial for brass life
Limitations:
- Temperature sensitivity (1.2-1.5 fps/°F) – approximately 3-5x more seasonal variation than Extreme series or Enduron alternatives; seasonal load verification required for consistent long-range POI
- Not at Extreme series stability levels – for year-round precision competition, Hodgdon H4350 or IMR 4451 Enduron are more appropriate
- 22-250 Remington application is marginal – the burn rate is too slow for efficient combustion in 22-250 Remington with standard 40-55 grain varmint bullets; Hodgdon H380 or Hodgdon Varget are better matched
- 6.5 Creedmoor is sub-optimal – the burn rate is slightly too fast for 6.5 Creedmoor with 140-143 grain match bullets; Hodgdon H4350 is the standard choice

Where Accurate 2700 Fits – The Medium-Slow Ball Position
Accurate 2700 sits in the medium-slow burn rate class alongside well-documented extruded and ball alternatives:
| Powder | Type | Density (g/cc) | Stability | Primary Applications |
|---|---|---|---|---|
| Hodgdon H4350 | SB Short-Cut | 0.860 | Extreme | 6.5 CM, 270 Win standard |
| IMR 4451 Enduron | SB Short-Cut | 0.909 | Enduron | 270 Win, 30-06, 7mm Rem Mag |
| Accurate 4350 | SB Short-Cut | 0.920 | Standard | 270 Win, 30-06 |
| Accurate 2700 | DB Ball | 0.975 | Standard | 30-06, 270 Win, 7mm Rem Mag |

| Alliant Reloder 19 | DB Extruded | 0.930 | Standard | 7mm Rem Mag, 300 Win Mag |
The original article mentions Hodgdon H414 as “essentially the same chemical twin” to Accurate 2700. This claim needs qualification. H414 and Accurate 2700 are both medium-slow double-base ball powders at similar burn rates and are sometimes used in overlapping applications. However, they are not the same powder from the same batch – they have different manufacturing origins and different charge weight requirements. Do not substitute H414 charge weights for Accurate 2700 or vice versa; always develop from each powder’s own published data.
Temperature Stability – Practical Hunting Assessment
1.2-1.5 fps per degree Fahrenheit is the documented sensitivity for Accurate 2700 – standard double-base ball behavior without modern stabilizer chemistry.
For a 270 Winchester hunting load at 2,950 fps developed at 65°F:
- At 95°F (+30°F summer practice): approximately 2,986-2,995 fps – 36-45 fps faster
- At 20°F (-45°F late season elk hunt): approximately 2,890-2,896 fps – 54-60 fps slower
At 400 yards, the cold-weather velocity drop produces approximately 1.5-2 inches of additional drop versus summer zero – meaningful for an ethical long-range hunting shot, and easily managed with a temperature-corrected drop chart or a field verification zero at hunting-season temperatures.
| Powder | 65°F Swing | At 300 yards | At 500 yards |
|---|---|---|---|
| Hodgdon H4350 | ~18-33 fps | <0.5″ | ~1″ |
| IMR 4451 Enduron | ~10 fps | <0.3″ | <0.5″ |
| Accurate 4350 | ~65-78 fps | ~1.5″ | ~2.5″ |
| Accurate 2700 | ~78-98 fps | ~1.5-2″ | ~3″ |
| Winchester 760 | ~98-117 fps | ~2″ | ~3.5″ |
Burn Rate Comparison and Competing Powders
vs. Hodgdon H4350: H4350 is the Extreme series benchmark for 270 Winchester and 6.5 Creedmoor – ~0.3 fps/°F stability, short-cut metering at ±0.1-0.15 grain, and the deepest precision data library in this burn rate class. Accurate 2700 meters slightly better from ball geometry and provides higher velocity from double-base energy. The stability difference is approximately 4-5x in H4350’s favor. For a hunter who wants to throw charges without weighing and verifies zero seasonally, Accurate 2700 is the production-efficiency choice. For year-round competition or maximum seasonal consistency, H4350 is more appropriate.
vs. Accurate 4350: Accurate 4350 is a single-base short-cut extruded powder at a comparable burn rate – better temperature stability (~1.0 fps/°F) than Accurate 2700, lower density (0.920 g/cc), and the single-base accuracy advantages. Accurate 2700 meters better from ball geometry and provides higher velocity from double-base energy. For precision single-stage loading, Accurate 4350 is more thermally stable. For high-volume progressive press production, Accurate 2700 is more practically efficient.
vs. Winchester 760: Winchester 760 is a double-base ball powder at a comparable burn rate with similar temperature sensitivity (~1.5-1.8 fps/°F). Both are legitimate choices in the same application cartridges. Charge weights are not interchangeable; load development in the specific rifle guides the final selection.
vs. Ramshot Hunter: Ramshot Hunter burns slightly slower than Accurate 2700 and is specifically well-suited for the heaviest bullets in 270 Winchester and 7mm Remington Magnum where the slower burn provides better case fill with heavy-for-caliber projectiles. Accurate 2700 is better matched for standard to mid-weight bullets in these cartridges. Both come from Western Powders’ Ramshot/Accurate lineup.
vs. Alliant Reloder 19: Alliant Reloder 19 is a double-base extruded powder at a slightly slower burn rate, specifically documented for 7mm Remington Magnum and 300 Winchester Magnum standard loads. Accurate 2700 meters better from ball geometry but is slightly faster – better matched for 30-06 Springfield standard loads; Reloder 19 is better matched for large magnum cases at maximum pressures.
The M1 Garand Caution
The original article includes a valuable note about M1 Garand use that deserves explicit treatment:
Accurate 2700 is not recommended for the M1 Garand. The medium-slow ball powder burn rate produces a gas port pressure timing that is suboptimal for the M1 Garand’s fixed gas system. The 4895-class powders (Accurate 2495, Hodgdon H4895, IMR 4895) were developed specifically for the 30-06 Springfield / M1 Garand combination and produce the gas port pressure profile that operates the mechanism safely. Using a slower powder like Accurate 2700 risks under-gassing the system – failures to cycle, short-stroking, and feeding malfunctions.
For 30-06 Springfield M1 Garand loading, use Accurate 2495 or Hodgdon H4895 specifically. For bolt-action 30-06 Springfield and modern semi-automatic actions with adjustable gas systems, Accurate 2700 is fully appropriate.
Recommended Cartridges and Applications
Accurate 2700 is most effective in standard and large long-action hunting cases where the burn rate produces efficient case fill at working pressures.
| Cartridge | Bullet Weight Range | Notes |
|---|---|---|
| 30-06 Springfield | 150-180 gr | Primary bolt-action application |
| 270 Winchester | 130-150 gr | Classic hunting application |
| 7mm Remington Magnum | 150-175 gr | Standard magnum hunting |
| 300 Winchester Magnum | 150-180 gr | Standard hunting weights |
| 243 Winchester | 85-105 gr | Standard hunting weights |
| 7mm-08 Remington | 140-162 gr | Standard to heavy hunting |
| 280 Remington | 140-175 gr | Mountain hunting loads |
30-06 Springfield with 150-180 grain bullets in bolt-action rifles is the application where Accurate 2700’s combination of high density, ball metering, and progressive pressure curve works most effectively. The 90-97% case fill eliminates position sensitivity and produces the consistent standard deviations that a hunter needs for accurate 400-yard field shots.
Applications the original article overstates:
22-250 Remington: The burn rate is too slow for efficient combustion in 22-250 Remington with standard 40-55 grain varmint bullets. Hodgdon H380 or Hodgdon Varget are appropriate for that application.
6.5 Creedmoor: The original article lists 6.5 CM with 120-130 grain bullets. Hodgdon H4350 is the standard benchmark for 6.5 Creedmoor. If published Western Powders data exists for Accurate 2700 in 6.5 Creedmoor, it would be with lighter 120-130 grain bullets where effective case volume reduction makes the slightly faster burn of Accurate 2700 more appropriate. Verify from current Western Powders published data.
Bullets
Accurate 2700 produces best results with standard-to-heavy-for-caliber hunting and precision bullets in the primary bore sizes where the progressive ball powder pressure curve provides consistent acceleration.

Primers
Accurate 2700 as a double-base ball powder responds well to standard large rifle primers in standard-capacity cases at moderate temperatures. For magnum-capacity cases at maximum charges or cold-weather use below 20°F, large rifle magnum primers improve consistency.
The original article lists “RWS 5333” as a primer. The correct designation for the RWS large rifle magnum primer is RWS 5337. Verify from current RWS documentation before ordering.
| Primer | Type | Application |
|---|---|---|
| Federal GM210M | Large Rifle Match | Competition precision – gold standard |
| CCI BR-2 | Large Rifle Benchrest | Competition lowest SD |
| CCI 200 | Large Rifle Standard | 30-06, 270 Win general development |
| Federal 210 | Large Rifle Standard | Consistent general use |
| Winchester WLR | Large Rifle Standard | Hunting loads |
| Remington 9-1/2 | Large Rifle Standard | Traditional pairing |
| CCI 250 | Large Rifle Magnum | 7mm Rem Mag, 300 Win Mag, cold weather |
| Federal 215 | Large Rifle Magnum | Maximum ignition for ball powders |
| Winchester WLRM | Large Rifle Magnum | Magnum case maximum charges |
| Remington 9-1/2M | Large Rifle Magnum | Cold weather magnum use |
| RWS 5337 | Large Rifle Magnum | Premium European competition |
| Fiocchi Large Rifle Magnum | Large Rifle Magnum | Consistent European alternative |
| Ginex Large Rifle | Large Rifle Standard | Cost-effective general use |
Metering and Equipment Compatibility
Accurate 2700’s ball geometry is the defining loading bench advantage. On a Dillon XL 750 or Hornady Lock-N-Load AP, charge-to-charge variance under 0.1 grains is achievable at normal cycling speeds – making high-volume hunting ammunition production practical without weighing every charge.
For precision single-stage loading, the RCBS ChargeMaster Supreme and Hornady Auto-Charge Pro handle the small dense spheres efficiently. The Frankford Arsenal Powder Trickler on a high-resolution scale for ±0.02 grain single-stage work eliminates any volumetric variance.
Static electricity: dense spherical grains accumulate static in plastic hoppers in dry conditions. Ground the drop tube or use an anti-static dryer sheet treatment for dry winter sessions.
Reloading Safety Notes
All charge weights must come from current published Western Powders / Accurate load data for Accurate 2700 specifically. Do not substitute Hodgdon H4350, IMR 4350, or Winchester 760 charge weights without independent verification. The density difference between Accurate 2700 (0.975 g/cc) and extruded alternatives (0.860-0.920 g/cc) makes charge weights non-interchangeable.
M1 Garand caution: Do not use Accurate 2700 in M1 Garand actions. Use Accurate 2495 or Hodgdon H4895 for 30-06 Springfield M1 Garand loading.
Temperature protocol: develop maximum charges at the highest expected firing temperature.
Start 10% below the listed maximum and work up in 0.3-grain increments. Watch for flattened primers, stiff bolt lift, ejector marks.
See the overpressure in reloading guide for systematic pressure sign identification.
FAQ
Is Accurate 2700 the same as Hodgdon H414?
No. The original article calls them “chemical twins” but this overstates the relationship. Both are medium-slow double-base ball powders at similar burn rates with overlapping applications. They are not the same powder from the same batch and have different charge weight requirements. Never substitute H414 charge weights for Accurate 2700 or vice versa without independent verification from published data for each.
Is Accurate 2700 a good choice for 270 Winchester?
Yes – for a hunter who values progressive press metering efficiency over Extreme series seasonal stability. Accurate 2700 produces accurate loads in 270 Winchester with 130-150 grain bullets and meters well for high-volume production. For year-round precision shooting or competition where seasonal zero consistency is essential, Hodgdon H4350 or IMR 4451 Enduron offer substantially better seasonal stability.
What is the neck tension recommendation for ball powders like Accurate 2700?
The original article’s 0.002-0.003 inch neck tension guidance is appropriate and applies to all powders – not specifically to spherical powders. Consistent neck tension produces consistent start pressure, which reduces extreme spread. This applies equally to extruded and ball powders.
Conclusion
Accurate 2700 occupies its position in the Western Powders lineup as the high-density ball powder workhorse for standard long-action hunting cartridges. Ball geometry metering efficiency, competitive velocity from double-base energy, and excellent case fill in 30-06 Springfield and 270 Winchester make it the practical choice for hunters who load at volume and manage seasonal variation through field verification rather than Extreme series stability.
Choose Accurate 2700 if you load 30-06 Springfield, 270 Winchester, or 7mm Remington Magnum at production volumes on progressive equipment and want ball powder metering efficiency with high case fill. Choose Hodgdon H4350 if Extreme series year-round stability is the priority for these cartridges. Choose IMR 4451 Enduron if Enduron temperature stability and decoppering chemistry are worth developing fresh loads. Choose Ramshot Hunter if very heavy bullets in 270 Winchester and 7mm Remington Magnum require the slightly slower burn that Hunter provides.
Editor’s note: Published load data and manufacturer specifications are the starting point – not the final word.
