Hodgdon H4831 is arguably the most legendary rifle propellant in the history of handloading, a powder that effectively birthed the modern reloading industry. Originally salvaged from military surplus after World War II by Bruce Hodgdon, this slow-burning, extruded powder became the definitive choice for the 270 Winchester and a host of other magnum and high-capacity cartridges. Today, Hodgdon H4831 is produced as part of the Extreme Series, ensuring that while the heritage remains, the technology is state-of-the-art.

Powder Description & Technical Profile
Hodgdon H4831 is a single-base extruded propellant. Unlike double-base powders that utilize nitroglycerin for increased energy, Hodgdon H4831 relies on a high-purity nitrocellulose base. This chemical foundation is the primary reason for its celebrated stability. The powder is available in two physical formats: the standard long-grain Hodgdon H4831 and the Hodgdon H4831SC (Short Cut). Both versions are chemically identical and share the same loading data, but the “SC” version features shorter kernels to facilitate better flow through mechanical powder measures.
The expert “feel” of Hodgdon H4831 is characterized by a “low-stress” pressure curve. It is a forgiving powder that rarely exhibits the sudden, unpredictable overpressure spikes seen in faster, more energetic propellants. Instead, Hodgdon H4831 builds pressure in a linear, predictable fashion, making it an ideal choice for reloaders who are developing loads for older rifles or for those who prioritize safety and brass longevity over chasing the absolute highest possible velocity.
Pros & Cons
- Pros:
- Part of the Hodgdon Extreme line; virtually unaffected by extreme heat or cold.
- Extremely high load density provides excellent “cushion” and ignition consistency.
- Decades of proven data available for almost every modern rifle cartridge.
- Decoppering agents help maintain bore accuracy over long strings of fire.
- Cons:
- The standard version (long grain) can be difficult to meter precisely in small-diameter drop tubes.
- Generally requires longer barrels (24 inches or more) to reach full velocity potential.
- Lower energy density than double-base competitors means larger charge weights are required.
Technical Characteristics
The technical profile of Hodgdon H4831 highlights its stability and physical volume. It is designed to fill cases efficiently, which is a key factor in reducing velocity spreads.
| Technical Property | Specification |
| Density (g/cc) | 0.895-0.915 |
| Burn Rate Category | Slow Rifle |
| Grain Shape | Extruded Cylinder (Standard or Short Cut) |
| Coating | Anti-Static Graphite & Decoppering Additive |
| Base Type | Single-Base Nitrocellulose |
Temperature Stability & Burn Rate Analysis
Hodgdon H4831 is a foundational member of the Extreme Series. The chemical engineering behind this powder ensures that the burn rate remains consistent whether the ambient temperature is -40 degrees or 110 degrees Fahrenheit. While many powders see a velocity change of 1.5 to 2.5 FPS per degree, Hodgdon H4831 typically stays under 0.5 FPS per degree. This is a critical factor for hunters who might zero their rifle in the humid heat of August but take their shot in the freezing mountains in November.
Stability Comparison Table
| Powder | Stability Rating | Temperature Sensitivity (FPS/Degree) |
| Hodgdon H4831 | Ultra-High | < 0.5 FPS |
| IMR 4831 | Moderate | 1.2-1.6 FPS |
| Alliant Reloder 22 | Moderate | 1.5-2.0 FPS |
Powder Comparison
To understand where Hodgdon H4831 fits in the current market, it is best compared against other slow-burning standards. It occupies the “sweet spot” for many 30-06-based wildcats and standard magnums.
| Powder Name | Burn Rate | Density (g/cc) | Primary Cartridges |
| IMR 4350 | Faster | 0.885 | 243 Winchester |
| IMR 4831 | Faster | 0.900 | 25-06 Remington |
| Hodgdon H4831 | Subject | 0.905 | 270 Winchester |
| Alliant Reloder 22 | Slower | 0.935 | 7mm Remington Magnum |
| Hodgdon H1000 | Slower | 0.925 | 300 Winchester Magnum |
Performance, Metering & Equipment
The metering characteristics of Hodgdon H4831 depend heavily on which version you choose. The standard long-grain version is known for “bridging” in small funnels and causing the occasional “crunch” in drum-style powder measures. This is why Hodgdon H4831SC was introduced.
- Metering Performance: If using a manual measure, the SC version is mandatory for consistency within 0.1 grains. With the standard long grain, expect variations of 0.3-0.5 grains unless using a digital dispenser.
- Recommended Equipment: For the most precise long-range loads, the RCBS ChargeMaster Lite Digital Powder Scale and Dispenser or the Frankford Arsenal Intellidropper 2.0 Digital Powder Scale and Dispenser are the preferred tools.
- Fouling & Cleanup: Hodgdon H4831 is a very clean-burning powder. The inclusion of decoppering agents means you can shoot more rounds between deep cleanings without a significant degradation in accuracy. For precision adjustments, a Frankford Arsenal Powder Trickler is an excellent addition to any bench using this powder.
Recommended Cartridges and Applications
Hodgdon H4831 is famously versatile, but it reaches its maximum efficiency in cases with a medium-to-large capacity relative to the bore diameter.
| Cartridge | Primary Application |
| 25-06 Remington | Exceptional for 100-120 grain bullets; flat shooting |
| 6.5 Creedmoor | High case-fill option for heavy 147 grain projectiles |
| 270 Winchester | The historical “Gold Standard” for this caliber |
| 280 Remington | Maximizes velocity with 140-160 grain hunting bullets |
| 7mm Remington Magnum | Ideal for 140-150 grain “all-around” hunting loads |
| 30-06 Springfield | Best for heavy 200-220 grain “thumper” loads |
| 300 Winchester Magnum | Efficient for 165-180 grain light-to-medium bullets |
| 338 Winchester Magnum | Excellent for heavy 250 grain projectiles |
Bullets
Hodgdon H4831 performs best when it has a significant amount of weight to push against. While it can work with lighter bullets, its internal ballistic efficiency peaks with the following bullet weights and models.
| Bullet Model | Recommended Weight (Grains) |
| Hornady ELD-X | 143-200 |
| Nosler Partition | 115-180 |
| Sierra GameKing | 130-200 |
| Berger VLD Hunting | 140-185 |
| Barnes TSX | 120-175 |
Primers
Because Hodgdon H4831 is a slow-burning extruded powder with a relatively high volume, a strong, consistent spark is necessary. While it is not as difficult to ignite as some spherical powders, using high-quality primers is paramount for low velocity spreads.
- CCI 200 Large Rifle Primer
- Federal 210 Large Rifle Primer
- Winchester WLR Large Rifle Primer
- Remington 9-1-2 Large Rifle Primer
- CCI 250 Magnum Large Rifle Primer (Recommended for Magnum cases)
- Federal 215 Magnum Large Rifle Primer (Recommended for large Magnum cases)
- RWS 5341 Large Rifle Primer
- Murom KVB-7 Large Rifle Primer
- Fiocchi Large Rifle Primer
Expert Verdict
Hodgdon H4831 is the rare product that lives up to its immense historical reputation. It remains a top-tier choice for any reloader seeking a balance of high performance and absolute reliability. Its place in the Hodgdon Extreme line makes it the “go-to” powder for hunters who travel across climate zones and for long-range shooters who cannot afford to have their ballistic data change with the weather. Whether you are loading for a vintage 270 Winchester or a modern long-range 7mm Remington Magnum, Hodgdon H4831 provides the consistency that wins matches and fills freezers.
Expert Pro Tip: If you are using Hodgdon H4831 in a standard long-action case like the 270 Winchester and find that you are running out of case capacity before reaching your target velocity, switch to Hodgdon H4831SC. The shorter kernels settle more densely in the case, often allowing for an extra 1.0 to 1.5 grains of powder without excessive compression. For the most consistent seating depth, use a Forster Co-Ax Bench Priming Tool to ensure your primers are perfectly uniform, and consider using a drop tube to help the large kernels settle evenly within the brass.
