- What This Guide Covers: Comprehensive technical specifications, temperature stability analysis, cross-powder comparisons, and optimized load applications.
Best For: Serious benchrest competitors, precision varmint hunters, and reloaders seeking match-grade consistency in 30 BR, 222 Remington, and 6.5 Grendel.
Powder Description & Technical Profile
Accurate LT-30 is a single-base, fine-grained extruded powder. While many high-precision propellants utilize larger cylindrical “sticks,” Accurate LT-30 features a significantly smaller physical geometry. This design allows the powder to flow through mechanical measures with the fluidity of a spherical powder while maintaining the internal ballistic stability of a single-base extruded propellant.
The expert “feel” of Accurate LT-30 is defined by its linear pressure curve. It provides a sustained, predictable push that minimizes standard deviation (SD) and extreme spread (ES) in muzzle velocity. During its development phase, Accurate LT-30 was famously used to set multiple world records in the 30 BR discipline, proving its ability to maintain a consistent “tune” even under the rigorous demands of competitive shooting.
Pros & Cons
- Pros:
- Unrivaled metering consistency for an extruded powder.
- Clean-burning properties that reduce fouling during long strings of fire.
- Optimized for the 30 BR, arguably the most accurate short-range cartridge in existence.
- Highly versatile in smaller cartridges like the 222 Remington and 300 Blackout.
- Cons:
- Limited application in large-capacity or magnum cartridges.
- More sensitive to temperature fluctuations than the Hodgdon Extreme series.
- Can be difficult to find during high-demand cycles due to its niche production.
Technical Characteristics
The physical and chemical composition of Accurate LT-30 is tailored for rapid ignition and complete combustion in short barrels and small cases.
| Property | Specification |
| Powder Type | Extruded (Fine-Grain) |
| Base Type | Single-Base |
| Bulk Density | 0.880-0.910 g/cc |
| Burn Rate Category | Fast Rifle |
| Grain Shape | Small Cylindrical |
| Coating | Graphite Surface Coating |
| VMD (cc/grains) | 0.072-0.076 |
Burn Rate and Temperature Stability
In the relative burn rate hierarchy, Accurate LT-30 sits between Accurate 1680 and Accurate LT-32. It is notably faster than IMR 3031 and shares a very similar burn speed with Hodgdon H4198. Because it is a single-base powder, Accurate LT-30 is generally more stable than traditional double-base ball powders; however, it does not feature the heavy chemical deterrents found in “temperature-insensitive” lines.
Shooters can expect velocity shifts of approximately 0.5-0.8 FPS per degree Fahrenheit. In practical terms, a 50-degree swing in ambient temperature might result in a 25-40 FPS change in muzzle velocity. For benchrest shooters, this requires slight adjustments to the seating depth or charge weight to stay within the “accuracy node.”
Stability Table
| Powder | Stability Category | FPS Variation (Est. per Degree F) |
| Hodgdon Benchmark | Highly Stable | 0.1-0.3 FPS |
| Accurate LT-30 | Moderate | 0.5-0.8 FPS |
| Hodgdon H335 | Sensitive | 1.2-1.5 FPS |
Powder Comparison
Choosing the right powder often involves comparing Accurate LT-30 against other favorites in the fast-rifle category.
4-Way Analysis
- Accurate 1680: This is a faster, double-base spherical powder. While it offers higher velocities in very small cases like the 22 Hornet, it lacks the match-grade precision and lower standard deviations of Accurate LT-30.
- Hodgdon CFE BLK: A slightly slower spherical powder optimized for the 300 Blackout. It contains copper-fouling erasers but often yields higher extreme spreads than Accurate LT-30 in bolt-action rifles.
- Norma 200: A close competitor in burn rate. Norma 200 is excellent for 222 Remington but usually has a slightly larger grain size, making it less fluid in standard powder measures.
- Accurate LT-32: The slower brother to Accurate LT-30. While Accurate LT-30 is king for the 30 BR, Accurate LT-32 is the industry standard for the 6mm PPC.
Comparison Table
| Powder | Burn Rate | Density (g/cc) | Primary Cartridges |
| Accurate LT-30 | Fast Rifle | 0.890 | 30 BR, 222 Remington |
| Accurate 1680 | Faster Rifle | 0.940 | 7.62×39, 300 Blackout |
| Hodgdon CFE BLK | Slower Rifle | 0.950 | 300 Blackout, 6.8 SPC |
| Accurate LT-32 | Slower Rifle | 0.920 | 6mm PPC, 223 Remington |
| Norma 200 | Fast Rifle | 0.860 | 222 Remington, 45-70 Government |
Applications and Performance
Accurate LT-30 excels in environments where precision is measured in thousandths of an inch. In the 30 BR, it provides the perfect fill ratio for the 112-118 grain bullets used in score shooting. Its clean-burning nature ensures that the “carbon ring” in the throat of the barrel develops slowly, allowing shooters to maintain their zero throughout a long match day.
In semi-automatic platforms, Accurate LT-30 is a standout for the 300 Blackout. It is fast enough to cycle actions reliably with subsonic loads while maintaining enough case fill to prevent “powder position” sensitivity. For the 6.5 Grendel, it works exceptionally well with lighter projectiles (90-100 grains), providing excellent velocity without the erratic pressure spikes often seen with faster ball powders.

Conclusion and Expert Verdict
Accurate LT-30 is a master-class propellant for the precision reloader. Its ability to combine the best traits of extruded and spherical powders makes it an indispensable tool for anyone shooting the 30 BR or looking for the “magic” load in a 222 Remington. While it may not be the most temperature-stable powder on the market, its raw accuracy potential and flawless metering more than compensate for the minor tuning adjustments required during seasonal changes.
Expert Pro Tip: Because Accurate LT-30 is so fine-grained, it is susceptible to “leakage” in some older, worn-out powder measures. For the best results, use a high-quality measure with tight tolerances, such as those from Redding or Forster. Additionally, when loading for the 30 BR, experiment with very light neck tension (0.001-0.002 inches) to fully exploit the powder’s ability to produce single-digit velocity SDs.
