Hodgdon Superformance

Published: 2026 | Last updated: May 2026

---

Hodgdon Superformance is a medium-burning, double-base spherical powder developed through a technical partnership between Hodgdon Powder Company and Hornady Manufacturing. It was engineered around a single specific goal: deliver 100-200 fps more muzzle velocity than conventional powders in the same cartridge without exceeding safe chamber pressures. It achieves this through a proprietary progressive burn technology built into the grain chemistry itself rather than relying on traditional surface deterrent coatings.

The result is a powder that is genuinely useful in the specific cartridges it was designed for – and genuinely inappropriate in many others. This is not a general-purpose powder and should not be treated as one. Superformance is a specialist tool for the specific case volumes and burn rate windows where Hodgdon’s engineering produced the velocity gains they documented. Outside those windows, the progressive burn technology provides no advantage and can produce erratic results.

Understanding which cartridges those are – and why several intuitive candidates like 7mm Remington Magnum are absent from the published data – is the most important practical knowledge a reloader needs before purchasing this powder.

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 Hodgdon Superformance 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

Hodgdon Superformance is a double-base, spherical powder. The double-base chemistry – nitrocellulose plus nitroglycerin – provides the high energy density per grain. The critical distinction from conventional double-base ball powders is in the grain chemistry: instead of standard surface deterrent coatings that control burn rate, Superformance uses a proprietary internal chemical architecture that produces a sustained progressive pressure curve extending the pressure plateau further down the bore.

In practical terms: standard powders produce a pressure spike that decays as the bullet accelerates. Superformance’s chemistry maintains higher pressure longer through the barrel, extracting more velocity from the same case volume. The “long push” that reloaders describe reflects this internal pressure behavior.

Bulk density is 0.940-0.965 g/cc – high, consistent with the dense packing of small spherical grains. In 22-250 Remington and 243 Winchester at working charge weights, case fill runs 90-97%, producing the near-complete case fill that contributes to the consistent standard deviations and clean burning the powder is known for.

Strengths:

• 100-200 fps velocity advantage over conventional powders in documented cartridges – the primary reason to choose this powder
• Ball geometry metering (±0.05-0.1 grains) – small spherical grains flow consistently through volumetric measures
• High bulk density (0.940-0.965 g/cc) produces excellent case fill in primary cartridges – clean burning and consistent ignition
• Reduced muzzle flash compared to older double-base formulations
• Smooth recoil impulse from the sustained pressure curve – less sharp spike than fast-burning alternatives

Limitations:

• Extremely cartridge-specific – the progressive chemistry that produces velocity gains in matched cartridges can produce erratic pressures in mismatched ones
• Not part of the Hodgdon Extreme series – temperature sensitivity (~0.8-1.2 fps/°F) is higher than H4350, H4895, or Varget; loads developed in cool conditions require verification in summer heat
• No published data for 223 Remington or 308 Winchester standard loads – the burn rate is mismatched to these cartridges
• No published data for 7mm Remington Magnum, 7mm WSM, and most large 7mm magnums – see dedicated section below

Why There Is No Published Data for Most 7mm Cartridges

This is the most frequently asked technical question about Hodgdon Superformance, and it deserves a direct, thorough answer because the intuition that drives the question is reasonable.

The intuition: Hornady sells factory ammunition in 7mm-08 Remington and 7mm Remington Magnum labeled “Superformance.” So why can’t you buy a canister of Superformance powder and replicate those loads?

The technical answer has two parts:

Part 1: Factory “Superformance” ammunition ≠ canister Superformance powder.

Hornady’s factory Superformance-branded ammunition uses proprietary industrial powder blends specifically formulated for each caliber. These are not the same as the retail canister powder sold as “Hodgdon Superformance.” The industrial blends are caliber-matched at the manufacturing level and are not available for retail sale. The canister powder is one specific formulation from the Superformance technology family – the one that worked across a specific set of case volumes. Buying a canister of Hodgdon Superformance and loading it into a 7mm Remington Magnum case is not replicating the factory process; it is using a different chemical formulation in a cartridge it was not optimized for.

Part 2: The burn rate mismatch with large 7mm cartridges.

The retail canister Superformance burns at a medium burn rate – approximately the H4350 class. This rate is well-matched to medium-capacity cases like 22-250 Remington, 243 Winchester, and 300 WSM.

For 7mm Remington Magnum – a significantly larger case – the medium burn rate is inefficient in one of two ways:

• At lower charge weights needed to stay under maximum pressure: the powder may produce incomplete combustion in the large case, resulting in poor standard deviations and excessive fouling
• At charge weights needed to fully utilize case capacity: the progressive chemistry that is the powder’s technical advantage produces pressure curves that are difficult to characterize safely in a case volume the chemistry was not matched to

Hodgdon tested these cartridges and chose not to publish data because the results did not meet their performance or safety criteria. That decision should be treated as definitive. Do not use Superformance in cartridges without published Hodgdon data.

The partial exception: Hodgdon does publish Superformance data for 7mm-08 Remington – a smaller, more moderate 7mm cartridge whose case volume is closer to the powder’s design window. This is an important distinction: it is not that all 7mm cartridges are excluded, it is that the large-capacity 7mm magnums specifically fall outside the burn rate window. Verify from current Hodgdon online data for the specific cartridge and bullet weight before assuming exclusion.

Temperature Stability – Practical Notes

~0.8-1.2 fps per degree Fahrenheit is the working temperature sensitivity for Superformance – standard double-base ball powder behavior. The progressive burn technology does not improve temperature stability; it addresses velocity and pressure profile.

For a 243 Winchester hunter zeroing at 60°F in August and hunting in 10°F December conditions (50°F colder), the velocity drop is approximately 40-60 fps. At 300 yards on deer-sized game, this produces approximately 1-1.5 inches of additional drop – worth noting and worth field-verifying at hunting conditions, not disqualifying.

Powder	60°F Swing	At 300 yards	At 400 yards
Hodgdon H4350	~18-30 fps	<0.5″	~1″
Hodgdon Superformance	~48-72 fps	~1-1.5″	~2″
Winchester 760	~90-120 fps	~2″	~3.5″

The specific recommendation for Superformance loads: develop maximum charges at the highest temperature you will fire the ammunition. A load at 90-95% of maximum charge validated at summer temperatures is safe year-round.

Burn Rate Comparison and Competing Powders

Powder	Type	Density (g/cc)	Burn Position	Key Character
Hodgdon H4350	SB Short-Cut	0.860	Slightly Faster	Extreme series benchmark
IMR 4451 Enduron	SB Short-Cut	0.909	Slightly Faster	Enduron stability
Hodgdon Superformance	DB Ball	0.950	Reference	Progressive velocity technology
Hodgdon H4831SC	SB Short-Cut	0.875	Slower	Extreme, magnum hunting
Alliant Reloder 19	DB Extruded	0.930	Slower	270 Win, 30-06 magnums
Ramshot Hunter	DB Ball	0.970	Slower	General magnum hunting

vs. Hodgdon H4350: H4350 is the Extreme series benchmark for 6.5 Creedmoor and 243 Winchester – approximately 3x more temperature-stable, single-base, and with the deepest precision data library. Superformance produces 50-100+ fps more velocity in these cartridges from its progressive chemistry. The choice is direct: year-round seasonal consistency favors H4350; maximum velocity at appropriate temperature protocol favors Superformance.

vs. Hodgdon H4831: H4831 burns slightly slower. In 25-06 Remington and 300 WSM, Superformance typically produces 100-150 fps more velocity at equivalent pressures from its progressive technology. H4831 is more temperature-stable. The trade-off mirrors the H4350 comparison.

vs. Alliant Reloder 19: Reloder 19 is a double-base extruded powder at a comparable burn rate known for 270 Winchester and 30-06 Springfield velocity. Superformance provides comparable or higher velocity in shared applications with better ball-geometry metering efficiency.

Recommended Cartridges and Applications

Hodgdon Superformance works only in the cartridges with published Hodgdon data. Do not assume the velocity advantages apply to unlisted cartridges.

Cartridge	Bullet Weight Range	Notes
22-250 Remington	50-55 gr	Maximum velocity varminting
243 Winchester	58-95 gr	Predator through deer
6.5 Creedmoor	120-143 gr	Long-range match and hunting
6mm Creedmoor	80-108 gr	Precision competition
25-06 Remington	90-120 gr	Flat-shooting hunting
30-06 Springfield	150-180 gr	Enhanced big game
300 WSM	165-200 gr	Maximum velocity elk loads
270 Winchester	130-150 gr	Long-range hunting
7mm-08 Remington	120-162 gr	Moderate 7mm applications

7mm-08 Remington appears on this list specifically because it is a moderate-capacity 7mm cartridge that falls within the powder’s design window. 7mm Remington Magnum, 7mm WSM, 7mm PRC, and similar large-capacity 7mm magnums do not have published Superformance data – see the dedicated section above.

Primers

Hodgdon Superformance as a dense double-base ball powder requires a consistent, adequately hot primer for reliable ignition of the proprietary grain chemistry. Standard large rifle primers work in most applications; the original article’s Pro Tip about “hot” primers is sound – magnum primers improve cold-weather ignition consistency.

Primer	Type	Application
Federal GM210M	Large Rifle Match	Competition precision – gold standard
CCI BR-2	Large Rifle Benchrest	Competition lowest SD
CCI 200	Large Rifle Standard	General load development
Federal 210	Large Rifle Standard	Reliable consistent ignition
Winchester WLR	Large Rifle Standard	Hot spark for spherical powder
CCI 250	Large Rifle Magnum	Cold weather, 300 WSM
Winchester WLRM	Large Rifle Magnum	Magnum cases cold weather
Remington 9-1/2	Large Rifle Standard	All-purpose development
RWS 5341	Large Rifle	Premium European precision
Fiocchi Large Rifle	Large Rifle Standard	International alternative
Sellier & Bellot V360587	Large Rifle Standard	Consistent international option

Metering and Equipment Compatibility

Hodgdon Superformance’s fine ball geometry provides ball powder metering performance. On a Dillon XL 750 or Hornady Lock-N-Load AP, charge-to-charge variance under 0.1 grains is achievable at normal cycling speeds.

For precision single-stage loading, the RCBS MatchMaster and Frankford Arsenal Powder Trickler combination achieves ±0.02 grain charge precision – important for maintaining the consistent case fill that produces Superformance’s lowest standard deviations.

Target case fill: 90-95%. Below this range, the progressive chemistry produces less consistent results and more carbon residue.

Reloading Safety Notes

All charge weights must come from current published Hodgdon load data for Superformance specifically. The proprietary progressive chemistry means data from other ball powders at similar burn rates does not safely transfer. Do not use H4350, Ramshot Hunter, or Alliant Reloder 19 charge weights as starting points.

If Hodgdon has not published data for your specific cartridge and bullet weight combination, do not load Superformance in that cartridge. This applies specifically to 7mm Remington Magnum, 7mm WSM, and similar large-capacity 7mm magnums.

Temperature protocol: develop maximum charges at the highest expected firing temperature. At 0.8-1.2 fps/°F, summer conditions elevate pressure from cool-weather developed loads.

Start 10% below the listed maximum and work up in 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

Why does Hodgdon publish Superformance data for 6.5 Creedmoor but not for 7mm Remington Magnum?

This is the most practical burn-rate question about this powder. The short answer: case volume and the progressive burn technology’s efficiency window.

6.5 Creedmoor is a medium-capacity cartridge (~53 grains water capacity) that falls within the case volume range where Superformance’s progressive chemistry produces the sustained pressure plateau that generates velocity gains. The powder fills the case efficiently and burns completely before the bullet exits the barrel.

7mm Remington Magnum is a belted magnum with approximately 93 grains water capacity – nearly double the 6.5 Creedmoor case. In this much larger case, Superformance’s burn rate is too fast relative to case volume: it peaks pressure early and cannot sustain the progressive plateau that produces velocity gains. The result is pressure-velocity behavior similar to any other medium-speed powder in a mismatched case – with the added risk that the proprietary chemistry was not calibrated or tested for this volume.

Hodgdon tested these large 7mm magnums and found the combination did not produce safe, consistent, or advantageous results. They did not publish data. That engineering decision is definitive.

Can I use Superformance in 7mm-08 Remington?

Yes – Hodgdon publishes Superformance data for 7mm-08 Remington. The 7mm-08 case (~52 grains water capacity) is close to 243 Winchester and 6.5 Creedmoor in capacity, placing it within the powder’s effective design window. Always verify against current Hodgdon online data for the specific bullet weight.

The factory Hornady Superformance 7mm Rem Mag ammunition uses a different, proprietary powder blend. Buying canister Superformance and loading 7mm Rem Mag is not replicating those factory loads – it is using a different chemical formulation in a mismatched case.

Why does Superformance produce 100-200 fps more velocity than H4350 in the same cartridge at the same pressure?

The velocity advantage comes from the internal grain chemistry rather than surface deterrent coatings. Conventional powders produce a sharp pressure peak that decays as the bullet moves down the bore. Superformance’s progressive chemistry maintains elevated pressure over a longer portion of the bullet’s bore travel. This sustained “push” extracts more kinetic energy from the same case volume and gas pressure – more work done on the bullet over a longer distance. The net result: higher exit velocity at the same peak chamber pressure. The trade-off is the highly caliber-specific nature of this chemistry, since the timing of the progressive curve must match the specific case volume and bullet weight.

Is Superformance appropriate for the M1 Garand?

No. Superformance is specifically documented for bolt-action platforms where the full barrel length extracts the benefit of the sustained pressure curve. The M1 Garand’s fixed gas system has a specific pressure-timing window (Hodgdon H4895 or Accurate 2495 are specifically matched for it). Superformance’s sustained pressure profile may produce over-gassing in the M1 Garand mechanism.

Conclusion

Hodgdon Superformance is precisely what its marketing describes: a specialty powder engineered for a specific set of cartridges where the progressive burn technology produces genuine, documented velocity advantages. In 243 Winchester, 22-250 Remington, 6.5 Creedmoor, and 300 WSM, it performs exactly as documented and earns its place on the shelf.

The 7mm cartridge questions are the most common source of reloader frustration with this powder, and the answer is specific: large-capacity 7mm magnums are outside the design window; 7mm-08 Remington is within it. Factory Superformance 7mm ammunition uses different industrial blends that are not replicated by the canister product.

Choose Hodgdon Superformance if 22-250 Remington, 243 Winchester, 6.5 Creedmoor, 25-06 Remington, or 300 WSM are your primary cartridges, you want 100-200 fps more velocity in those specific applications, and you can manage the seasonal temperature protocol. Choose Hodgdon H4350 if year-round Extreme series temperature stability is the priority in these same cartridges. Choose Hodgdon H4831SC if the 270 Winchester and 7mm Remington Magnum class of cartridges are the primary application and Extreme series stability is required.
