Ramshot TAC is a medium-fast-burning, double-base spherical powder from Western Powders, specifically designed for the heavy-bullet 223 Remington and standard 308 Winchester precision and tactical applications. It sits in the burn rate position that covers 223 Remington with 62-77 grain match bullets and 308 Winchester with 150-168 grain service rifle loads – the two most commonly loaded competition cartridges in North America.
The powder’s defining practical properties are the same ones that define the Ramshot ball powder lineup: ball geometry metering precision (±0.04-0.08 grains), high bulk density (0.980 g/cc) producing excellent case fill, and double-base energy density providing maximum velocity. The clean-burning additive package and flash suppressor treatment make it specifically practical for high-volume AR-15 and precision rifle sessions where copper accumulation and muzzle signature are practical concerns.
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 Ramshot TAC 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
Ramshot TAC is a double-base, spherical powder with technical deterrent coatings including flash suppression. The double-base chemistry provides the energy density per grain that allows 223 Remington 77-grain match bullets to reach competitive velocities and 308 Winchester service rifle bullets to produce reliable gas-operated cycling pressure.
The spherical geometry produces ball powder metering – charge-to-charge variance of ±0.04-0.08 grains on quality progressive equipment. For a competitive shooter loading 500 rounds of heavy-bullet 223 Remington for a season’s matches on a Dillon CP 2000 or Dillon RL 1100, this metering consistency is the enabling property.
Bulk density is 0.980 g/cc – very high for a medium-fast rifle powder. In 223 Remington with 69-77 grain heavy match bullets at working charge weights, case fill runs 90-97%, producing the consistent ignition and low position sensitivity that precision AR-15 and service rifle accuracy requires.
Strengths:
- Ball geometry metering (±0.04-0.08 grains) – enables high-volume progressive press production
- Flash suppression in the coating – useful for low-light tactical and competition applications
- High bulk density (0.980 g/cc) produces excellent case fill in 223 Remington heavy-bullet loads
- Clean-burning additive package – reduces carbon fouling accumulation rate compared to standard double-base ball powders
- Documented for 308 Winchester and 223 Remington semi-automatic gas system cycling
Limitations:
- Temperature sensitivity of ~0.8-1.0 fps/°F – standard double-base ball powder behavior; not at Extreme series levels
- 22-250 Remington standard light varmint loads are marginal – burn rate is slightly slow for 40-55 grain standard varmint bullets in 22-250 Remington
- 30-06 Springfield application is limited – appropriate only for lighter 150-165 grain standard loads; the burn rate is slightly fast for heavier 30-06 Springfield loads
- 35 Whelen application is edge case – verify from current Western Powders data

The original article’s Varget density (0.885 g/cc) is corrected here to ~0.910 g/cc. The Alliant Reloder 15 density (0.925 g/cc) is corrected to ~0.920 g/cc.
Temperature Stability – Practical Assessment
0.8-1.0 fps per degree Fahrenheit – standard double-base ball powder behavior. For 223 Remington and 308 Winchester competition use:
| Powder | 60°F Swing | At 300 yards | At 600 yards |
|---|---|---|---|
| Hodgdon Varget | ~25-30 fps | <0.5″ | ~1″ |
| Hodgdon H4895 | ~18 fps | <0.4″ | <1″ |
| Ramshot TAC | ~48-60 fps | ~1″ | ~2″ |
| Accurate 2520 | ~48-72 fps | ~1″ | ~2″ |
| Alliant Power Pro 2000-MR | ~72-90 fps | ~1.5-2″ | ~3″ |
At typical service rifle competition distances (300-600 yards), the 1-2 inch seasonal variation requires temperature-corrected firing solutions for long-range stages. For varmint hunting and tactical training at 0-400 yards, the variation is manageable with a current-season zero.
Burn Rate Comparison and Competing Powders
vs. Hodgdon Varget: The most important comparison for the 223 Remington and 308 Winchester markets. Varget is Extreme series single-base at ~<0.5 fps/°F – approximately 2x more seasonally stable. It meters less consistently from short-cut geometry. Ramshot TAC meters better from ball geometry, produces slightly higher velocity from double-base energy, and burns with flash suppression. For year-round precision competition where seasonal consistency is essential, Varget is the more stable choice. For high-volume progressive press tactical and competition production, Ramshot TAC is the metering-efficiency choice.
vs. Hodgdon H335: H335 burns slightly faster – optimized for 223 Remington with standard 55-62 grain bullets and 5.56 NATO specifications. Ramshot TAC is better matched for 223 Remington with heavier 69-77 grain match bullets where H335’s faster burn is slightly inefficient. For 308 Winchester service rifle loads, Ramshot TAC is better matched than H335.
vs. Accurate 2460: Accurate 2460 burns at a nearly identical position to Ramshot TAC with the same application range: 223 Remington heavy-bullet and 308 Winchester service rifle. Both are double-base ball powders at 0.980 g/cc with comparable metering. The choice between them comes down to which produces better standard deviations in the specific rifle from load development testing. Charge weights are not directly interchangeable.
vs. Accurate 2520: Accurate 2520 burns slightly slower and is the Camp Perry NRA High Power powder specifically for 308 Winchester with 168-175 grain match bullets. Ramshot TAC is slightly faster and covers 223 Remington heavy-bullet loads more efficiently. For 308 Winchester with 150-168 grain service rifle bullets, both work well; for 308 Winchester with 168-175 grain precision bullets, Accurate 2520 is slightly better matched.
vs. Alliant Power Pro 2000-MR: Power Pro 2000-MR burns at a similar but slightly slower position, specifically maximizing velocity in 308 Winchester and 6.5 Creedmoor at the expense of higher temperature sensitivity. Ramshot TAC is more broadly versatile across both 223 Remington and 308 Winchester.
Recommended Cartridges and Applications
Ramshot TAC is most effective in medium-capacity cases with standard-to-heavy-for-caliber bullet weights in the two most common North American precision rifle calibers.
| Cartridge | Bullet Weight Range | Notes |
|---|---|---|
| 223 Remington | 62-77 gr | Primary – heavy match bullets |
| 308 Winchester | 150-168 gr | Primary – service rifle loads |
| 6mm ARC | 90-108 gr | Gas gun precision |
| 7mm-08 Remington | 140-162 gr | Balanced hunting loads |
| 6.5 Grendel | 100-123 gr | Semi-auto precision |
| 22-250 Remington | 55-65 gr | Heavier varmint only – see note |
| 30-06 Springfield | 150-165 gr | Standard loads only – see note |
| 35 Whelen | 200-250 gr | Verify from current data |
223 Remington with 62-77 grain heavy match bullets is the primary application where Ramshot TAC specifically outperforms the faster alternatives. The burn rate is calibrated for these heavier, longer bullets in the 223 Remington case – Accurate 2230 and H335 are too fast for maximum efficiency with 69-77 grain bullets.
22-250 Remington note: The original article lists 22-250 Remington as “high-speed varmint hunting.” Ramshot TAC’s burn rate is slightly slow for standard 40-55 grain varmint bullets in 22-250 Remington. Appropriate only for heavier 55-65 grain bullets in this cartridge where effective case volume reduction makes the slower burn rate more efficient. For standard 22-250 Remington varmint loads, Hodgdon H380 or Hodgdon Varget are better matched.
30-06 Springfield note: Appropriate only for lighter 150-165 grain standard loads where the burn rate is efficient. For standard 30-06 Springfield hunting and M1 Garand loads, Hodgdon H4895 or Accurate 2495 are better matched at the 4895-class burn rate. Verify from current Western Powders published data.

Primers
Ramshot TAC 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 and M14/AR-10 semi-automatic platforms, mil-spec hard-cup primers are required to prevent slam-fire.
| 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 |
| Federal GM205M | Small Rifle Match | Bolt-action competition |
| CCI BR-4 | Small Rifle Benchrest | Precision bolt-action |
| CCI 400 | Small Rifle Standard | General 223 Rem development |
| Remington 7-1/2 | Small Rifle Bench Rest | Bolt-action precision |
| Federal GM210M | Large Rifle Match | 308 Win competition precision |
| CCI No. 34 | Large Rifle Magnum (Mil-Spec) | Required for M14/M1A, AR-10 |
| Winchester WLR | Large Rifle Standard | 308 Win hunting loads |
| Fiocchi Small Rifle Magnum | Small Rifle Magnum | Cold weather ignition |
| Sellier & Bellot V361617 | Small Rifle Standard | General use international |
| RWS 4033 | Small Rifle | Premium European precision |
CCI No. 41 for AR-15 and CCI No. 34 for M14/AR-10 are required for semi-automatic gas-operated platforms. Standard primer cups can detonate from the inertia of the free-floating firing pin with dense ball powder charges.
Metering and Equipment Compatibility
Ramshot TAC’s ball geometry delivers ball powder metering precision on any quality equipment. On a Dillon CP 2000, Dillon RL 1100, or Hornady Lock-N-Load AP, the Dillon Precision Case Activated Powder Measure Assembly handles Ramshot TAC with near-liquid flow consistency.
The Pro Tip in the original article about 0.003-inch neck tension is correct practical guidance – consistent neck tension produces consistent start pressure, which is universally important for all powders. This applies equally to extruded and ball powders, not specifically to spherical chemistry.
Static electricity management applies as with all fine ball powders in dry conditions.
Reloading Safety Notes
All charge weights must come from current published Western Powders / Ramshot load data for Ramshot TAC specifically. Do not substitute Hodgdon H335, Accurate 2460, or Hodgdon BL-C(2) charge weights without independent verification.
Temperature protocol: develop maximum charges at the highest expected firing temperature. At 0.8-1.0 fps/°F, a load at maximum charge developed in cool competition weather may show elevated pressure in summer heat.
Semi-automatic platform primers are not optional. CCI No. 41 for AR-15 / CCI No. 34 for AR-10/M1A.
Start 10% below the listed maximum and work up in 0.2-0.3 grain increments. Watch for flattened primers, stiff bolt lift, ejector marks.
See the overpressure in reloading guide for systematic pressure sign identification.
FAQ
Is Ramshot TAC better than Varget for 223 Remington 77-grain precision loads?
They serve the same application with different trade-offs. Varget is approximately 2x more seasonally stable (~<0.5 fps/°F Extreme vs ~0.8-1.0 fps/°F for Ramshot TAC) and is the benchmark for year-round precision competition. Ramshot TAC meters better from ball geometry for high-volume production and may produce higher velocity in specific barrels. For a competition shooter preparing hundreds of rounds for a season’s matches on a progressive press, Ramshot TAC is the production-efficiency choice. For year-round competition across seasonal temperatures without recalibration, Varget is the more stable choice.
How does Ramshot TAC compare to Accurate 2460?
Both are double-base ball powders at nearly identical burn rate positions (0.980 g/cc), covering 223 Remington heavy-bullet and 308 Winchester service rifle loads. The choice between them is a load development question – which produces better standard deviations in your specific barrel. Neither has a meaningful metering advantage over the other.
Conclusion
Ramshot TAC delivers exactly what the original article promises: a high-volume tactical workhorse ball powder that covers 223 Remington with heavy 69-77 grain match bullets and 308 Winchester service rifle loads from a single canister with ball powder metering efficiency and flash suppression.
Choose Ramshot TAC if you load 223 Remington with 62-77 grain heavy match bullets or 308 Winchester service rifle loads at high volume and want ball powder metering precision with flash suppression. Choose Hodgdon Varget if Extreme series year-round temperature consistency is the priority. Choose Accurate 2460 if the same ball powder burn rate from the Western Powders Accurate family is preferred. Choose Hodgdon H335 if 223 Remington with standard 55-62 grain training bullets is the primary application.
