Ramshot X-Terminator is a fast-to-medium-burning, double-base spherical powder from Western Powders, produced by Eurenco in Belgium and specifically developed for 223 Remington varmint and tactical applications where high-volume production, clean burning, and consistent velocities in light-to-standard bullet weight loads are the combined priority.
The powder’s relationship to Accurate 2230 is worth addressing directly: the original article states they were “historically the exact same Belgian propellant.” The two do occupy nearly identical burn rate positions (both ~0.975 g/cc, both fast-to-medium double-base ball) and published load data is often near-identical. Whether they are from the same current production batch is a supply chain question that Western Powders has not definitively confirmed in public documentation. The practical guidance: treat them as different commercial products with separately published data – verify from each powder’s own current data and work up independently.
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 X-Terminator 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 X-Terminator is a double-base, spherical powder produced by Eurenco (Belgian manufacturer). The double-base chemistry – nitrocellulose plus nitroglycerin – provides energy density that drives 223 Remington 40-55 grain bullets to maximum varmint velocities at appropriate pressures.
The fine spherical geometry produces ball powder metering – charge-to-charge variance of ±0.04-0.07 grains on quality equipment. For a varmint hunter loading 500-round sessions on a progressive press, this metering consistency eliminates the per-charge overhead that extruded alternatives require.
Bulk density is 0.975 g/cc – high, consistent with other Eurenco/Ramshot ball powders in this class. In 223 Remington with standard 55-grain bullets at working charge weights, case fill runs 90-97%.
The temperature stability claim in the original article (“65 FPS across 150°F range”) works out to approximately 0.43 fps/°F – significantly better than typical double-base ball powder behavior (0.8-1.5 fps/°F). This figure, if accurate, would approach Extreme series performance. The prudent working assumption is 0.6-1.0 fps/°F for seasonal load planning – if your specific lot performs better, that is a practical bonus.
The clean-burning reputation is well-documented in the varmint hunting community: reduced carbon accumulation between cleaning sessions compared to older-generation double-base ball powders. This matters specifically for 300-500 round prairie dog sessions where barrel maintenance affects session productivity.
Strengths:
- Ball geometry metering (±0.04-0.07 grains) – production efficiency for high-volume varmint loading
- Clean burning – less carbon accumulation per round count than standard double-base ball powders; longer productive sessions before accuracy-affecting fouling
- High bulk density (0.975 g/cc) – excellent case fill in 223 Remington at standard varmint bullet weights
- Specific 223 Remington varmint optimization – the burn rate is precisely positioned for this case and 40-55 grain bullet weight range
- Belgian manufacturing (Eurenco) – tight lot-to-lot consistency from the same facility that produces several other Western Powders products
Limitations:
- Temperature sensitivity (~0.6-1.0 fps/°F working assumption) – not at Extreme series levels; loads developed in cool conditions can approach elevated pressure in extreme heat
- 45-70 Government application requires pressure tier awareness – same three-tier safety framework as with all fast powders in the large 45-70 case
- 308 Winchester standard loads are not primary application – burn rate is fast for 308 Winchester with standard 150-175 grain bullets; appropriate only for very light 110-125 grain loads
- 17 Remington application requires verification – the burn rate may be at the slower end for efficient 17 Remington combustion; verify from current Western Powders data

The X-Terminator / Accurate 2230 Relationship
The original article claims these two powders are “the exact same Belgian propellant sold under different labels.” This is a widely repeated assertion in the reloading community that deserves honest treatment.
What is documented: Both are double-base ball powders produced in Belgium (Eurenco), at nearly identical bulk density (~0.975 g/cc), at nearly identical burn rate positions, with published load data in many cartridges that is near-identical.
What is not definitively confirmed: That they are from the same current production batch with identical deterrent coating chemistry. Western Powders has not publicly confirmed this, and manufacturing processes can diverge.
The practical guidance: Published load data for Ramshot X-Terminator and Accurate 2230 in overlapping cartridges is typically near-identical. Many reloaders use one when the other is unavailable with minimal adjustment. However: always start from each powder’s own published minimum and work up independently – do not assume identical charge weights. If you are switching from one to the other mid-season, treat the new canister as a new powder and verify velocity before committing to production.
Temperature Stability – Honest Assessment
The “65 FPS across 150°F” figure in the original article works out to 0.43 fps/°F – notably better than typical double-base ball powder chemistry. This figure appears in Western Powders published documentation. However, field experience in the reloading community shows more typical double-base behavior for most lots.
Working assumption for seasonal planning: 0.6-1.0 fps/°F.
For varmint hunting applications:
- A 60°F morning-to-afternoon temperature swing produces approximately 36-60 fps velocity variation
- At 300 yards on a prairie dog: approximately 0.8-1.3 inches of vertical shift
- For typical varmint hunting distances (0-400 yards), this is manageable with a temperature-aware approach
If your specific lot shows the documented 0.43 fps/°F performance, the variation is negligible at any practical varmint distance. The conservative approach: develop loads at the highest expected firing temperature.
| Powder | 60°F Swing | At 300 yards | At 400 yards |
|---|---|---|---|
| Hodgdon Benchmark | ~22-30 fps | <0.5″ | <0.8″ |
| Ramshot X-Terminator | ~36-60 fps | ~0.8-1.3″ | ~1.5-2″ |
| Accurate 2230 | ~48-72 fps | ~1-1.5″ | ~2″ |
| Hodgdon H335 | ~60-90 fps | ~1.5″ | ~2.5″ |
Burn Rate Comparison and Competing Powders
| Powder | Type | Density (g/cc) | Burn Position | Key Application |
|---|---|---|---|---|
| Hodgdon H335 | DB Ball | 0.980 | Slightly Faster | 223 Rem 5.56 standard |
| Ramshot X-Terminator | DB Ball | 0.975 | Reference | 223 Rem varmint specialist |
| Accurate 2230 | DB Ball | 0.975 | Similar | 223 Rem, 308 Win (light) |
| Ramshot TAC | DB Ball | 0.980 | Slightly Slower | 223 Rem heavy, 308 Win service |
| Hodgdon Benchmark | SB Micro-Grain | 0.920 | Slightly Slower | 204 Ruger, 223 Rem, Extreme |
| IMR 8208 XBR | SB Short-Cut | ~0.895 | Slightly Slower | 6.5 Grendel, 308 Win (light) |
| Hodgdon H322 | SB Fine-Cut | 0.893 | Slightly Faster | 6mm PPC, 222 Rem, Extreme |
The original article’s Accurate 2230 density (0.985 g/cc) is corrected to ~0.975 g/cc.
vs. Accurate 2230: Near-identical burn rate and density. See the dedicated section above on the relationship. Both are viable choices; develop from each powder’s own published data.
vs. Hodgdon H335: H335 burns slightly faster – the standard 5.56 NATO ball powder specifically documented for 223 Remington with 55-62 grain standard loads. X-Terminator and H335 compete directly in the same application space; the difference is production origin (Belgium vs USA) and specific lot characteristics. X-Terminator is specifically praised for cleaner burning.
vs. Hodgdon Benchmark: Benchmark is an Extreme series single-base micro-grain powder at a slightly slower burn rate – approximately 3x more temperature stable, less carbon residue from single-base chemistry, but not at ball powder metering levels. For precision varmint work where Extreme stability is the priority, Benchmark is the more appropriate choice. For high-volume progressive press production where metering efficiency is the priority, X-Terminator is the practical choice.
vs. Ramshot TAC: Ramshot TAC burns slightly slower – better matched for 223 Remington with heavy 62-77 grain match bullets and 308 Winchester service rifle loads. X-Terminator is better matched for 223 Remington with standard 40-55 grain varmint bullets where TAC’s slightly slower burn is at the edge of efficiency.
Recommended Cartridges and Applications
Ramshot X-Terminator is specifically effective in small-capacity varmint cases with light-to-standard bullet weights.
| Cartridge | Bullet Weight Range | Notes |
|---|---|---|
| 223 Remington | 40-60 gr | Primary varmint application |
| 222 Remington | 40-55 gr | Classic precision varmint |
| 204 Ruger | 24-40 gr | Flat-shooting predator |
| 6mm ARC | 90-108 gr | Gas gun precision – verify |
| 6.5 Grendel | 90-100 gr | Light-bullet applications – verify |
| 308 Winchester | 110-125 gr | Very light bullets only |
| 45-70 Government | 300-405 gr | Pressure tiers – see note |
| 17 Remington | 20-25 gr | Verify from current data |
45-70 Government pressure tier note: As with all fast-burning powders in the large 45-70 Government case, the three pressure tiers must be respected: Trapdoor (~14,000-20,000 PSI), lever-action (~28,000-40,000 PSI), modern single-shot (~50,000-60,000 PSI). Use only published data developed for the specific tier matching your rifle. X-Terminator at Trapdoor/lever-action pressures fills the large case efficiently from a modest charge weight.
17 Remington note: The original article lists 17 Remington as an application for “maximum velocity.” Verify from current Western Powders published data before loading – the burn rate may be at the slower edge for 17 Remington’s very small case.
308 Winchester note: Appropriate only for very light 110-125 grain bullets where the burn rate is efficient. Standard 150-175 grain 308 Winchester loads require Hodgdon Varget or Hodgdon H4895.

Metering and Equipment Compatibility
Ramshot X-Terminator’s fine spherical grains produce the metering efficiency that defines Ramshot ball powders. On a Dillon XL 750 or Hornady Lock-N-Load AP, the Dillon Precision Case Activated Powder Measure Assembly handles X-Terminator with near-liquid flow at normal cycling speeds.
The Pro Tip in the original article about using a trickler for initial accuracy development and then trusting the volumetric measure for bulk production is sound practical workflow. The first 50-round load development session to find the accuracy node (hand-weighed precision), then several hundred rounds of production (volumetric measure) is the standard high-volume varmint loading approach.
The neck tension guidance (0.002 inch minimum) applies universally to all powders, not specifically to spherical powders.
Reloading Safety Notes
All charge weights must come from current published Western Powders / Ramshot load data for X-Terminator specifically. Do not use Accurate 2230 data interchangeably without starting from the published minimum and verifying velocity – the two powders are similar but not certified identical by the manufacturer.
Temperature protocol: use 0.6-1.0 fps/°F as the working seasonal planning assumption. Develop maximum charges at the highest expected firing temperature.
[45-70 Government] pressure tier matching is mandatory. Trapdoor, lever-action, and modern single-shot data are not interchangeable.
Start 10% below the listed maximum and work up in 0.2-0.3 grain increments. Watch for flattened primers, stiff bolt lift, ejector marks.
See the overpressure in reloading guide for systematic pressure sign identification.
FAQ
Is Ramshot X-Terminator the same powder as Accurate 2230?
They are similar in burn rate, density, and origin (Belgian Eurenco manufacturing), and published load data is often near-identical. Western Powders has not definitively confirmed they are from the same current production batch with identical chemistry. Treat them as separate commercial products with their own published data – if switching from one to the other, start from the new powder’s published minimum and verify velocity.
Is the 65 FPS / 150°F stability figure accurate?
This figure (approximately 0.43 fps/°F) appears in Western Powders’ own documentation. Field experience in the community shows some lots performing better than standard double-base ball chemistry typically would. Use 0.6-1.0 fps/°F as the planning assumption – better-than-expected field performance is a practical bonus, not a guaranteed specification.
Conclusion
Ramshot X-Terminator occupies a well-defined and useful position: a clean-burning, well-metering double-base ball powder specifically developed for 223 Remington varmint production and the adjacent small-bore cartridges where its burn rate and density combination produce consistent high-volume results.
Choose Ramshot X-Terminator if you load 223 Remington with 40-55 grain varmint bullets at high volume for progressive press production and value Belgian-made clean-burning ball powder performance. Choose Accurate 2230 if the same application with wider published data coverage in North American manuals is preferred. Choose Hodgdon Benchmark if Extreme series year-round temperature stability is the priority for varmint precision. Choose Hodgdon H335 if 5.56 NATO military heritage documentation and slightly faster burn for 55-62 grain standard FMJ loads are specifically needed.
