Hodgdon International is a cornerstone of the celebrated Clays series of propellants, specifically engineered to bridge the gap between ultra-fast target powders and medium-rate versatile handgun propellants. Known as International Clays in some markets, Hodgdon International was developed to provide a specialized solution for 20-gauge shotshell reloaders who required a propellant that could maintain consistent pressure with 7/8 oz loads while burning exceptionally clean. Over time, its reputation for consistency and thermal stability has led to its widespread adoption among handgun reloaders who seek a slightly slower burn rate than Hodgdon Clays but without the increased volume of Hodgdon Universal.
As a single-base powder, Hodgdon International is characterized by its high nitrocellulose content and distinct absence of nitroglycerin, which fundamentally dictates its thermodynamic behavior. In the contemporary reloading landscape of 2026, where efficiency and firearm longevity are paramount, this propellant remains a favorite for its ability to produce high-velocity target loads with minimal residue. Whether you are a competitive clay shooter looking for a soft-recoiling 20-gauge load or a handgun enthusiast refining a 9mm Luger or 45 ACP target recipe, Hodgdon International provides a technical profile that balances economy with top-tier performance.

Powder Description & Technical Profile
Hodgdon International is a single-base, flake propellant that features a large surface-area-to-volume ratio, designed to facilitate rapid ignition and a consistent pressure curve. Unlike double-base powder formulations that rely on nitroglycerin for energy, the single-base nature of Hodgdon International allows it to burn at lower temperatures, which is often cited as a benefit for reducing throat erosion in high-volume shooting applications. The physical geometry consists of medium-sized, grayish-green flakes that have been treated with specific deterrents to ensure the burn remains progressive enough for the slightly heavier payloads found in 20-gauge shells compared to 12-gauge target rounds.
One of the defining technical traits of Hodgdon International is its “fluffiness” or low bulk density. This physical characteristic is essential for shotshell reloading, where the powder must occupy a specific volume to ensure proper wad pressure and a consistent crimp. In handgun cases, this increased volume serves as a safety feature, making it much easier to detect a double-charge during a visual inspection of the loading block or on a progressive press. While its flake geometry was historically criticized for metering variations in small-aperture measures, modern equipment has largely mitigated these concerns, allowing Hodgdon International to compete with spherical vs extruded powder in terms of practical consistency.

Technical Characteristics
The technical profile of Hodgdon International highlights its specialized role as a mid-range target propellant. Its density is specifically tuned to work with standard 20-gauge wads and various hull configurations.
| Feature | Specification |
| Manufacturer | Hodgdon Powder Company |
| Powder Type | Single-Base |
| Grain Shape | Flake |
| Base Type | Nitrocellulose |
| Relative Burn Rate Category | Fast-Medium |
| Density (g/cc) | 0.450 – 0.480 |
| Primary Application | 20-gauge target and handgun target loads |
The density of Hodgdon International is significantly lower than that of spherical powders like Winchester 231. For the handloader, this means that while the powder is efficient, it provides a high degree of case fill, which often contributes to better ignition consistency in large-volume revolver cases such as the 38 Special or 44 Special.
Temperature Stability & Burn Rate Analysis
In the hierarchy of propellants, Hodgdon International occupies a critical position on the burn rate chart. It is significantly slower than its sibling, Hodgdon Clays, which is optimized for light 12-gauge loads. Conversely, it is faster than Hodgdon Universal, which is the preferred choice for 28-gauge and 20-gauge field loads. This “Goldilocks” positioning makes Hodgdon International the primary choice for 20-gauge shooters who want a powder that is fast enough to be efficient but slow enough to keep peak pressures safe with 7/8 oz payloads.
Temperature stability for Hodgdon International is a standout feature of its single-base construction. While double-base powders can exhibit pressure sensitivity as temperatures rise, Hodgdon International remains remarkably linear in its performance. In testing, it shows less velocity deviation across a 0-100 degree Fahrenheit range than many legacy flake powders like Alliant Unique. While it does not utilize the same technology as the “Extreme” rifle powders like Hodgdon Varget, its performance in the handgun and shotshell realm is considered industry-leading for its class.
Powder Comparison
When selecting Hodgdon International, reloaders often weigh it against other multipurpose target and field powders.
| Powder | Relative Burn Rate | Density | Primary Cartridges |
| Hodgdon International | Fast-Medium (Subject) | 0.465 | 20-gauge, 9mm Luger |
| Hodgdon Clays | Faster | 0.415 | 12-gauge, 45 ACP |
| Hodgdon Universal | Slower | 0.515 | 20-gauge field, 40 SW |
| Alliant Unique | Slower | 0.480 | 20 gauge, 45 ACP |
Compared to Hodgdon Clays, Hodgdon International offers a safer pressure margin for 7/8 oz 20-gauge loads, where Clays might spike too rapidly. Against Alliant Unique, Hodgdon International is substantially cleaner-burning and requires less maintenance of the firearm. While Hodgdon Universal is more versatile for high-velocity handgun applications, Hodgdon International often provides better accuracy in light-recoil target rounds.
Performance, Metering & Equipment
One of the primary considerations when using Hodgdon International is its physical flow through reloading equipment. As a flake powder, it lacks the fluid-like metering of spherical propellants like Accurate No. 2. However, the “New Technology” flakes used in the Clays series are much more uniform than older formulations. When using a precision volumetric measure like the Lyman Brass Smith Powder Measure, Hodgdon International typically drops with a consistency of +/- 0.1 to 0.2 grains, which is more than sufficient for target applications.
For high-volume production on a progressive press like the Dillon XL 750 or Hornady Lock-N-Load AP, reloaders should ensure their powder bar is clean and free of static. The low density of Hodgdon International means that the powder hopper will empty faster than with denser powders, so careful monitoring of the powder level is required. When loading for maximum accuracy in handgun calibers, using an automated trickler or a high-end dispenser can further tighten velocity spreads.
Recommended Cartridges and Applications
While its primary market is the 20-gauge clay target shooter, Hodgdon International has a dedicated following in several standard handgun calibers where clean-burning accuracy is the priority.
| Cartridge | Primary Application |
| 20-gauge | 7/8 oz Skeet and Trap Loads |
| 9mm Luger | Standard Velocity 115-124 grain Target |
| 45 ACP | Low-Recoil 185-200 grain Target |
| 38 Special | 148-158 grain Wadcutter/Target |
| 40 SW | Practice and Plinking Loads |
| 12-gauge | Heavy 1-1/8 oz Target Loads |
In the 9mm Luger, Hodgdon International is a sleeper choice for those who find Hodgdon Titegroup to be too hot-burning or sensitive. It provides a very soft recoil impulse that is highly favored for rapid-fire drills. In the 38 Special, the powder’s bulk ensures that the charge is well-positioned against the primer, leading to excellent vertical consistency.
Bullets
Choosing the right bullet for Hodgdon International requires matching the projectile to its mid-to-fast burn speed. It is most efficient with standard-weight or lightweight bullets for a given caliber.
| Bullet Model | Weight Range | Recommended Application |
| Sierra MatchKing | 125 grain | 9mm Target Accuracy |
| Nosler Custom Competition | 115 grain | 9mm Luger Target |
| Sierra Sports Master | 185 grain | 45 ACP Target |
| Hornady Interlock | 158 grain | 38 Special Range |
| Berry’s Plated | 124 grain | High-Volume Practice |
For the competitive 45 ACP shooter, pairing Hodgdon International with a 200-grain semi-wadcutter creates a load that is both remarkably accurate and soft-shooting. The clean-burning nature of the powder is particularly noticeable when using lead or coated bullets, as it generates significantly less “smoke” than legacy double-base powders.
Primers
As a single-base powder, Hodgdon International is relatively easy to ignite and does not require the intense brisance of a magnum primer. However, because flake powders can be sensitive to the volume of the ignition flash, selecting a consistent, high-quality primer is essential for maintaining low standard deviations.
Recommended Primers for Hodgdon International:
- CCI 500 (Small Pistol) – The standard for 9mm target loads.
- Winchester WSP (Small Pistol) – Excellent consistency in 38 Special.
- Federal 100 (Small Pistol) – Best for tuned revolvers with light springs.
- CCI 300 (Large Pistol) – Reliable choice for 45 ACP Bullseye.
- Federal 150 (Large Pistol) – High sensitivity and consistent ignition.
- Winchester WLP (Large Pistol) – A versatile, hot primer that works well with flakes.
- Sellier & Bellot V360157 (Small Pistol) – Cost-effective for high-volume 9mm.
- Remington 9-1/2 (Large Rifle) – Only for specific black powder cartridge gallery loads.
In the 20-gauge world, the choice of primer is often dictated by the hull being used, but in handguns, the CCI 500 and Winchester WSP remain the most common pairings for Hodgdon International. For competitive shooters, the Federal 100 is often the preferred option to ensure 100 percent reliability during rapid-fire stages.
Conclusion & Expert Verdict
Hodgdon International is a testament to the enduring value of specialized propellant engineering. While it may not have the extreme versatility of “universal” powders, its performance within its specific window – 20-gauge targets and standard handgun calibers – is nearly unmatched. By prioritizing a clean burn and a predictable pressure curve, Hodgdon has provided reloaders with a tool that enhances both the shooting experience and the longevity of their firearms.
For the reloader, the primary value of Hodgdon International is found in its consistency. In an era where components can be scarce, having a powder that delivers the same results lot after lot is an invaluable asset. Whether you are standing at the 16-yard line with a 20-gauge or at the 25-yard target stand with a 9mm Luger, Hodgdon International provides the ballistic integrity needed to perform at the highest levels. It remains a top-tier choice for any reloader who values cleanliness, accuracy, and safety.
Expert Pro Tip: When loading Hodgdon International in high-volume progressive presses, consider using a specialized powder baffle in your hopper. Because the flake geometry of Hodgdon International is low-density, the weight of the powder column at the top of a full hopper can exert different pressures on the metering bar than when it is nearly empty. A baffle ensures a consistent “head” of powder over the metering aperture, which can cut your charge weight variations in half and further tighten your velocity spreads.
