In the world of precision reloading, few propellants are as universally respected for their consistency as Hodgdon Benchmark. As part of the prestigious Extreme series of propellants, Hodgdon Benchmark was engineered specifically to meet the demands of benchrest shooters and small-bore varmint hunters who require absolute thermal stability and precise metering. It has earned a reputation as the “go-to” choice for those looking to shrink group sizes in small-to-medium capacity rifle cartridges.
Whether you are aiming for a tiny cluster on a paper target at several hundred yards or pursuing high-velocity varmint control in the field, Hodgdon Benchmark provides the predictable performance needed to excel. This guide covers everything from its technical profile to its ideal component matches.
Executive Summary
- Main Application: Precision target shooting and high-velocity varmint hunting in small-to-medium rifle cases.

- Burn Rate: Fast-to-medium rifle propellant, optimized for light-to-midweight projectiles.
- What This Guide Covers: Detailed technical specifications, temperature stability analysis, market comparisons, and component pairing recommendations.
Best For: Benchrest competitors, varmint hunters using 223 Remington, and reloaders seeking sub-MOA precision.
Powder Description & Technical Profile
Hodgdon Benchmark is a single-base, extruded (stick) propellant. What distinguishes it from many other stick powders is its incredibly small grain size. These “micro-grains” were developed to solve the historical conflict between the inherent accuracy of extruded powders and the easy metering of spherical powders.
The Expert “Feel”
Reloaders often describe Hodgdon Benchmark as “crisp”. It ignites easily and burns very rapidly for an extruded powder, creating a sharp, clean pressure curve that is ideal for shorter barrels and smaller calibers. It is particularly well-known for producing very low Standard Deviations (SD) in muzzle velocity, which is the primary metric benchrest shooters use to judge a powder’s quality.
Pros & Cons
- Pros:
- Leading-edge temperature stability (Hodgdon Extreme series).
- Meters as well as many spherical powders due to its tiny grain size.
- Clean-burning with very little residual carbon fouling.
- Excellent accuracy nodes with light-to-midweight bullets.
- Cons:
- Slower velocities when used with very heavy-for-caliber bullets.
- Can be overkill for casual plinking due to its premium price point.
Technical Characteristics
The physical properties of Hodgdon Benchmark make it one of the easiest extruded powders to work with on a progressive press or a high-speed powder measure.
| Property | Specification |
| Manufacturer | Hodgdon Powder Company |
| Powder Type | Extruded (Micro-Stick) |
| Base | Single-Base |
| Density | Approximately 0.920 g/cc |
| Burn Rate Category | Fast-Medium Rifle |
| Coating | Technical deterrents for temperature stability |
Temperature Stability & Burn Rate Analysis
As a member of the Hodgdon Extreme line, Hodgdon Benchmark is designed to be virtually unaffected by ambient temperature changes. Whether you are shooting in a 100°F desert or a 10°F winter landscape, your muzzle velocity will remain remarkably consistent.
In technical testing, Hodgdon Benchmark typically shows velocity variations of less than 0.5 FPS per degree Fahrenheit. This makes it a superior choice for hunters who zero their rifles in the fall but hunt in freezing conditions, or competitors who shoot day-long matches where the sun can significantly heat up the firing line.

| Powder Name | Stability Level | Tech Category |
| Hodgdon Benchmark | Extreme | Insensitive Extruded |
| Accurate 2495 | Moderate | Standard Extruded |
| Winchester 748 | Sensitive | Double-Base Spherical |
Powder Comparison
Hodgdon Benchmark sits in a very competitive burn rate window, often compared to other precision-oriented powders.
- Hodgdon H322: Slightly faster than Hodgdon Benchmark. H322 is another benchrest favorite but is often better suited for very small cases like the 6mm PPC.
- Vihtavuori N133: The European rival for benchrest supremacy. While N133 is incredibly clean, Hodgdon Benchmark is generally considered more temperature-stable.
- Accurate 2230: A spherical powder that is very popular for 223 Remington. It meters even better than Hodgdon Benchmark but lacks the Extreme series’ temperature stability.
- IMR 8208 XBR: Very similar in performance and application. 8208 XBR is slightly slower and often preferred for 123-grain bullets in 6.5 Grendel, whereas Hodgdon Benchmark shines with lighter varmint bullets.
Competitor Comparison Table
| Powder | Burn Rate | Density (g/cc) | Primary Cartridges |
| Hodgdon Benchmark | Fast-Medium | 0.920 | 223 Remington, 204 Ruger |
| Hodgdon H322 | Fast | 0.895 | 6mm PPC, 222 Remington |
| IMR 8208 XBR | Medium | 0.915 | 6mm ARC, 308 Winchester |
| Accurate 2230 | Fast-Medium | 0.985 | 223 Remington, 30-30 Winchester |

Performance, Metering & Equipment
Metering Consistency
Because the kernels are so small, Hodgdon Benchmark flows through powder measures like the Hornady Lock-N-Load Bench Rest Powder Measure with near-perfect accuracy. It rarely “cuts” grains in the measure, which is a common complaint with larger stick powders like IMR 4064. For those using an RCBS ChargeMaster Supreme Digital Powder Scale and Dispenser, this powder settles instantly and provides high-speed, high-precision results.
Fouling and Cleanliness
Hodgdon Benchmark is a remarkably clean-burning powder. It leaves behind very little carbon residue, which is critical for varmint hunters who may fire hundreds of rounds in a single afternoon. Maintaining a clean barrel longer means accuracy remains high throughout the entire shooting session.
Recommended Cartridges and Applications
This propellant is a specialized tool for small-bore and medium-capacity rifle cartridges.
| Cartridge | Primary Application |
| 204 Ruger | High-velocity varminting with 32-40 grain bullets |

Conclusion & Expert Verdict
Hodgdon Benchmark is the definitive “precision-first” powder for the reloader who refuses to compromise. Its ability to combine the thermal stability of the Extreme line with the easy metering of a spherical powder makes it a unique and invaluable tool for competitive shooters and varmint hunters alike. While it may not be the cheapest powder on the market, the dividends it pays in reduced group sizes and “zero-hassle” performance are well worth the investment.
If you are loading for 223 Remington or 204 Ruger, Hodgdon Benchmark should be one of the first propellants you test in your load development process.
Expert Pro Tip: When using Hodgdon Benchmark in 223 Remington, don’t be afraid to experiment with the lower end of the charge data for 52-grain match bullets. Many of the world’s tightest groups have been shot with this powder at moderate pressures where the burn is most stable and consistent.
