Ramshot Grand is a slow-burning, double-base spherical powder manufactured in the United States and distributed by Western Powders. It is the newer, more technically capable member of the Ramshot magnum lineup – positioned at a slightly faster burn rate than Ramshot Magnum and carrying two additive packages that its predecessor lacks: integrated decoppering chemistry and modern temperature-stabilizing technology.
Its burn rate position – between Hodgdon H1000 and Hodgdon Retumbo on the Hodgdon relative burn rate chart – places it precisely in the territory where the modern precision magnum cartridges operate most efficiently: 300 PRC, 7mm PRC, 6.5 PRC with heavy bullets, and 300 Winchester Magnum with heavy-for-caliber projectiles. These cartridges are large enough that H1000’s burn rate is slightly fast, and not large enough to fully utilize Retumbo’s ultra-slow burn.
The honest framing: Ramshot Grand is a newer powder with a smaller documented field data base than H1000 or Retumbo. The temperature stability claims (0.45-0.65 fps per degree Fahrenheit) are field estimates from early adopters rather than the decades-deep verified record of the Extreme series. The decoppering chemistry and ball powder metering are genuine advantages. Evaluating it honestly requires treating it as a promising newer alternative to established powders rather than a proven substitute.
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 Ramshot Grand 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
Ramshot Grand is a double-base, spherical powder with two additive packages engineered into the grain structure. Both characteristics – the chemistry and the geometry – drive its practical behavior.
The double-base chemistry – nitrocellulose plus nitroglycerin – provides higher energy per gram than single-base alternatives at this burn rate. In the 300 PRC and 7mm PRC cases, this energy advantage typically produces 50-80 fps more velocity than Hodgdon H1000 at the same pressure level. The nitroglycerin also provides more reliable cold-weather ignition than single-base alternatives – a practical benefit for late-season hunting in sub-zero conditions.
The spherical geometry produces the metering consistency that is the primary practical advantage of Ramshot Grand over any extruded competitor. Uniform spheres pack into a measure drum consistently at any cycling speed. Charge-to-charge variance under 0.05-0.10 grains on quality progressive equipment is achievable – significantly better than the 0.2-0.4 grain variance of extruded slow-magnum powders like H1000 or Retumbo.
The temperature-stabilizing additive package is the critical differentiator from Ramshot Magnum. Modern deterrent chemistry integrated into the grain regulates burn rate as ambient temperature changes. Field-estimated stability of 0.45-0.65 fps per degree Fahrenheit represents a substantial improvement over Ramshot Magnum’s 0.87 fps/°F and is genuinely competitive with Alliant Reloder 26’s EI technology at ~0.5 fps/°F.
The integrated decoppering agent works chemically during combustion to prevent copper jacket material from fully bonding to bore steel. In a 300 PRC or 7mm PRC precision barrel that sees high round counts per season, the extended accuracy interval between full copper removal sessions is practically useful.
Bulk density is 0.985 g/cc – extremely high, comparable to Alliant Reloder 26 at 0.989 g/cc and significantly denser than single-base extruded alternatives. This extreme density produces the same consequence as with other high-density ball powders: lower case fill percentage at working pressures than extruded alternatives. Visual case inspection is an unreliable pressure indicator with Ramshot Grand – a partially-filled case is not an under-pressured load. Rely entirely on published charge weights.
Strengths:
- Temperature stability (~0.45-0.65 fps/°F) – substantially better than Ramshot Magnum (0.87 fps/°F) and competitive with Alliant Reloder 26 EI technology
- Ball powder metering under 0.1 grain variance – superior to any extruded slow-magnum powder on progressive equipment
- Integrated decoppering chemistry extends accuracy maintenance intervals
- 50-80 fps velocity advantage over single-base H1000 at comparable pressures
- Specifically positioned for modern PRC cartridges – burn rate calibrated for 300 PRC, 7mm PRC, 6.5 PRC
- US-manufactured – different supply chain from European powder alternatives
Limitations:
- Newer product with smaller field data base than H1000, Retumbo, or Alliant Reloder 26. The temperature stability figures are field estimates from early adopters, not decades-verified performance
- Temperature stability (0.45-0.65 fps/°F) does not match Extreme series – H1000 at 0.21 fps/°F and Retumbo at 0.3 fps/°F are measurably more stable year-round
- Very high density produces low case fill – visual case inspection unreliable as a pressure indicator
- Magnum primers required in all applications – heavy deterrent coating on dense double-base ball powder needs adequate brisance
- Double-base flame temperature accelerates throat erosion compared to single-base alternatives in high-round-count applications
- The original article’s claim of US manufacture requires verification – PB Clermont Belgium produces multiple Ramshot and Accurate powders; confirm current manufacturing location from Western Powders directly

The Ramshot Family Context
Ramshot Grand is the most technically advanced powder in the Ramshot rifle lineup, carrying additive packages that the older Ramshot Magnum and Ramshot Hunter do not have:
| Powder | Burn Rate | Density | Stability | Decoppering |
|---|---|---|---|---|
| Ramshot Hunter | Faster | Moderate | ~1.0 fps/°F | No |
| Ramshot Magnum | Slower | 1.002 g/cc | ~0.87 fps/°F | No |
| Ramshot Grand | Between H1000/Retumbo | 0.985 g/cc | ~0.45-0.65 fps/°F | Yes |
The three powders are not interchangeable by application. Ramshot Grand is the modern precision cartridge specialist in the lineup. Ramshot Magnum remains appropriate for the larger cases where Grand burns slightly too fast.
Temperature Stability – Honest Assessment for a New Powder
The 0.45-0.65 fps per degree Fahrenheit stability estimate for Ramshot Grand is the most important number in the technical profile – and the one most requiring honest qualification.
This figure comes from field testing and early adopter reports, not the decades-deep, independently verified Extreme series database behind H1000’s 0.21 fps figure. The field estimate is based on enough testing to be credible, but the confidence level differs from established benchmarks.
With that qualification stated, the competitive position is clear:
| Powder | Stability | Source | 70°F swing |
|---|---|---|---|
| Hodgdon H1000 | 0.21 fps/°F | Decades verified | ~15 fps |
| Hodgdon Retumbo | ~0.3 fps/°F | Extreme series | ~21 fps |
| Ramshot Grand | 0.45-0.65 fps/°F | Field estimate | ~32-46 fps |
| Alliant Reloder 26 | ~0.5 fps/°F | EI technology | ~35 fps |
| Winchester StaBALL HD | 0.5-0.8 fps/°F | StaBALL additive | ~35-56 fps |
| Ramshot Magnum | ~0.87 fps/°F | Field verified | ~61 fps |
Ramshot Grand at its estimated 0.45-0.65 fps/°F is substantially better than Ramshot Magnum and comparable to Alliant Reloder 26 and Winchester StaBALL HD. A 70°F seasonal swing producing 32-46 fps variation results in approximately 2-3 inches of vertical deviation at 800 yards – manageable for hunting applications, borderline for year-round ELR competition.
What field experience can confirm: reloaders who have chronographed Ramshot Grand loads across seasonal temperature ranges consistently report stability better than Ramshot Magnum and comparable to the EI-impregnated extruded powders. Leave a comment with your chronograph data if you have seasonal results.
Burn Rate Comparison and Competing Powders
| Powder | Type | Density (g/cc) | Key Character |
|---|---|---|---|
| Hodgdon H1000 | Single-Base Extruded | 0.910 | Slightly Faster – Extreme stability |
| Alliant Reloder 26 | Double-Base Extruded | 0.989 | Similar – EI tech, extruded |
| Winchester StaBALL HD | Double-Base Ball | ~1.000 | Similar – StaBALL stability |
| Ramshot Grand | Double-Base Spherical | 0.985 | Reference |
| Ramshot Magnum | Double-Base Spherical | 1.002 | Slightly Slower – older, less stable |
| Hodgdon Retumbo | Single-Base Extruded | 0.925 | Slightly Slower – Extreme stability |
| Alliant Reloder 33 | Double-Base Extruded | 0.985 | Slower – 338 Lapua heavy |
vs. Hodgdon H1000: The single most important comparison. H1000 is the Extreme series benchmark at this burn rate – 0.21 fps/°F verified across decades, the deepest published data library among slow-magnum powders, and lower flame temperature from single-base chemistry. Ramshot Grand produces 50-80 fps more velocity, meters dramatically better on progressive equipment, and adds decoppering chemistry. The trade-off is well-defined: ultimate year-round stability plus single-stage convenience goes to H1000; maximum velocity plus ball metering efficiency plus decoppering goes to Ramshot Grand.
vs. Hodgdon Retumbo: Retumbo burns slightly slower and is the Extreme series choice for ultra-overbore cases – 300 RUM, 30-378 Weatherby. For 300 PRC and 7mm PRC, Ramshot Grand’s slightly faster burn is often better matched to the case volume. For the largest ultra-overbore cases, Retumbo remains appropriate.
vs. Alliant Reloder 26: Reloder 26 is a double-base extruded powder with comparable estimated stability (~0.5 fps/°F from EI technology) and comparable density (0.989 g/cc). It produces slightly higher velocity than Ramshot Grand in some applications from its energy content. Ramshot Grand meters better from ball geometry. Reloder 26 carries the above-85°F non-linear pressure concern that Ramshot Grand does not have documented. Both are legitimate modern alternatives to Extreme series powders in the slow-magnum class; the choice between them comes down to loading method and the specific cartridge application.
vs. Winchester StaBALL HD: StaBALL HD is the closest direct competitor – also a double-base ball powder with temperature-stabilizing additives and decoppering chemistry at a comparable burn rate and density. Both carry the same general stability tier (0.5-0.8 fps/°F range). StaBALL HD is slightly denser and was specifically developed for the PRC cartridge family with a Winchester-endorsed load development basis. Ramshot Grand carries a slightly deeper field data record as the earlier market entry. For a reloader choosing between them, application-specific load development in the specific barrel is the most reliable guide.
vs. Ramshot Magnum: Ramshot Magnum burns slightly slower, lacks the temperature-stabilizing additives, and lacks decoppering chemistry. Ramshot Grand is the more technically capable modern version for the PRC and standard magnum cartridges. Ramshot Magnum retains relevance for applications where its slightly slower burn rate is better matched and where the deeper legacy data history matters.
Recommended Cartridges and Applications
Ramshot Grand’s specific burn rate position – between H1000 and Retumbo – defines its most efficient applications. It is too slow for standard medium-capacity cartridges and best matched to the modern overbore precision magnums.
| Cartridge | Bullet Weight Range | Notes |
|---|---|---|
| 300 PRC | 200-230 gr | Primary application – excellent fit |
| 7mm PRC | 160-195 gr | Primary precision hunting application |
| 6.5 PRC | 140-156 gr | Heavy bullet applications |
| 300 Winchester Magnum | 190-220 gr | Heavy-bullet ELR loads |
| 338 Lapua Magnum | 250-285 gr | Standard competition weights |
| 300 Norma Magnum | 200-230 gr | ELR precision |
| 7mm Remington Magnum | 175-195 gr | Heavy-bullet maximum velocity |
| 28 Nosler | 160-195 gr | Overbore high-BC loads |
The 300 PRC and 7mm PRC are the applications where Ramshot Grand is most specifically optimized. Hornady designed both cartridges around heavy, high-BC bullets at maximum ELR velocities, and the case capacity of each was calibrated for a powder in exactly this burn rate range. With H1000 in these cartridges, the burn rate peaks slightly too fast for maximum efficiency; with Retumbo, slightly too slow. Ramshot Grand is the precision ball powder option that fills this specific gap.
Low case fill note: The 0.985 g/cc density produces case fill of approximately 85-93% at working pressures in most primary applications – lower than what extruded powders produce at comparable pressure. Do not increase charges to achieve higher visual fill.
Bullets
Ramshot Grand produces best results with heavy, high-BC projectiles in its primary magnum bore sizes, where the sustained pressure from the spherical geometry provides the most complete acceleration.
| Brand | Model | Weight | Cartridge | Application |
|---|---|---|---|---|
| Berger | Hybrid Target | 195-230 gr | 300 PRC / 300 Norma | ELR Competition |
| Berger | LRHT | 195-230 gr | 300 PRC / 300 Win Mag | Long-Range Hunting |
| Hornady | ELD-M | 195-230 gr | 300 PRC / 300 Win Mag | Long-Range Match |
| Hornady | ELD-X | 175-212 gr | 7mm PRC / 300 PRC | Long-Range Hunting |
| Sierra | MatchKing | 175-250 gr | 7mm PRC / 300 PRC / 338 Lapua | Competition |
| Sierra | Tipped MatchKing | 195-230 gr | 300 PRC / 300 Win Mag | Match Precision |
| Berger | VLD Hunting | 168-195 gr | 7mm PRC / 300 Win Mag | Long-Range Hunting |
| Lapua | Scenar-L | 250-285 gr | 338 Lapua Magnum | ELR Competition |
| Nosler | AccuBond | 175-210 gr | 7mm PRC / 300 PRC | Bonded Hunting |
| Barnes | LRX | 175-210 gr | 7mm PRC / 300 PRC | Lead-Free Long Range |

Primers
Magnum large rifle primers are mandatory for Ramshot Grand in all applications. The high-density double-base ball powder with deterrent coating requires adequate brisance for complete ignition in large-capacity cases. Standard large rifle primers produce elevated extreme spread with this powder.
| Primer | Type | Application |
|---|---|---|
| Federal GM215M | Large Rifle Magnum Match | Competition precision – gold standard |
| CCI 250 | Large Rifle Magnum | General magnum applications |
| Winchester WLRM | Large Rifle Magnum | Consistent hunting and match |
| Remington 9-1/2M | Large Rifle Magnum | Standard magnum hunting choice |
| Federal 215 | Large Rifle Magnum | Maximum ignition for large cases |
| CCI BR-2 | Large Rifle Benchrest | Competition where magnum brisance confirmed |
| RWS 5337 | Large Rifle Magnum | Premium European precision option |
| Fiocchi Large Rifle Magnum | Large Rifle Magnum | Consistent alternative |
When transitioning from a load developed with standard large rifle primers to Ramshot Grand, begin with a 5% reduction from your previous maximum and work back up. Primer brisance change can shift pressure meaningfully at the top of the charge range.
Metering and Equipment Compatibility
Ramshot Grand’s ball geometry is its primary practical advantage over extruded competitors in this burn rate class. On quality progressive equipment, charge-to-charge variance under 0.05-0.10 grains is achievable – a level that makes high-volume precision magnum loading practical without constant scale verification.
For high-volume production on a Dillon XL 750 or Dillon RL 1100, the spherical grains flow consistently at progressive cycling speeds. The Dillon Precision Case Activated Powder Measure Assembly handles small spherical grains at high cycling rates.
For precision single-stage loading, auto-dispensers including the RCBS ChargeMaster Supreme and Hornady Auto-Charge Pro dispense Ramshot Grand efficiently. The dense spherical grains trickle quickly without bridging.
Static electricity management applies – ground the measure’s drop tube or treat the hopper interior with an anti-static dryer sheet for loading sessions in dry winter conditions.
Reloading Safety Notes
All charge weights must come from current published Western Powders load data for Ramshot Grand specifically. As a newer product, the published data library is growing – use Hodgdon’s online data tool which covers Western Powders products. Do not substitute H1000, Retumbo, or Ramshot Magnum charge weights without independent verification.
Visual case fill is not a reliable pressure indicator. The 0.985 g/cc density produces 85-93% case fill at appropriate pressures – substantially lower than extruded powders. A partially-filled case is not under-pressure. Rely on published data, not visual comparison.
Start 10% below the listed maximum and work up in 0.3-grain increments. The original article correctly warns about rapid pressure increases near maximum with high-density powders – this is accurate. Do not skip increments near maximum.
See the overpressure in reloading guide for systematic pressure sign identification.
FAQ
How does Ramshot Grand compare to Hodgdon H1000 for 300 PRC?
H1000 is slightly faster and typically the more efficient Extreme series choice for 300 PRC at standard bullet weights – its burn rate peaks slightly earlier and may produce better case fill than Ramshot Grand in this cartridge. Ramshot Grand produces comparable or slightly higher velocity, meters better on progressive equipment, and adds decoppering. For single-stage hand-weighed precision loading where Extreme stability is the priority, H1000 is the more conservative choice. For progressive press production where ball metering and decoppering matter, Ramshot Grand is the practical alternative.
Is Ramshot Grand better than Retumbo for 300 PRC?
Retumbo burns slightly slower and may produce lower case fill in 300 PRC than ideal. Ramshot Grand’s slightly faster burn rate is a better match for 300 PRC case volume – this is the “Goldilocks” positioning the original article describes. Retumbo is the more appropriate choice for ultra-overbore cases like 300 RUM.
How reliable are the temperature stability figures for Ramshot Grand?
The 0.45-0.65 fps/°F estimate is based on early field reports and adopter chronograph data, not a decade-verified independent test record. The figures are credible enough to serve as a working estimate, but they carry less certainty than the Extreme series numbers. Chronograph your loads across the full seasonal temperature range you will shoot in and track the actual variation in your specific cartridge and barrel. This is genuinely useful data that the community needs – post your results in the comments.
Conclusion
Ramshot Grand represents a well-positioned modern option in the slow-magnum ball powder market. The burn rate calibration for the PRC cartridge family is specific and technically justified. The temperature-stabilizing additives produce a meaningful improvement over Ramshot Magnum and make Grand competitive with EI-impregnated extruded alternatives. The ball powder metering advantage over extruded competitors is real and practically useful. The decoppering chemistry adds value for high-round-count precision seasons.
The honest limitations: newer product with a smaller verified data base, temperature stability estimates rather than decades-confirmed performance, and the standard high-density ball powder caveats around case fill inspection and magnum primer requirements.
Choose Ramshot Grand if you load 300 PRC, 7mm PRC, or 338 Lapua Magnum at volume on a progressive press and want ball powder metering with temperature-stabilizing additives and decoppering chemistry at this specific burn rate position. Choose Hodgdon H1000 if Extreme series year-round stability verified over decades is the primary criterion and extruded metering is acceptable. Choose Hodgdon Retumbo if ultra-overbore cases like 300 RUM are the primary application. Choose Winchester StaBALL HD if you want a direct ball powder competitor with comparable stability additive technology and Winchester’s specific PRC-optimized load development basis.

Editorial note: Originally published 2026, revised May 2026. The revision added the Ramshot family lineup table showing how Grand relates to Magnum and Hunter, qualified the temperature stability figures as field estimates with lower confidence than the Extreme series, added the manufacturing location clarification note, corrected the Reloder 26 comparison – the original article’s claim that Reloder 26 is “more abrasive on throats” is unsupported and was removed, added the visual case fill warning, extended the bullet and primer tables with full internal links, added three community data disclaimer blocks in the correct blockquote format, and specifically invited community chronograph temperature data given the newer product status.
