Powder Description & Technical Profile
Ramshot X-Terminator is a double-base, spherical (ball) propellant produced by Eurenco in Belgium. Its double-base chemistry, consisting of both nitrocellulose and nitroglycerin, provides a high energy density that allows reloaders to achieve impressive velocities even in cases with limited capacity. The physical geometry is characterized by extremely small, uniform kernels that flow with the fluidity of fine sand.
The Expert “Feel”
Reloaders typically describe the experience of using Ramshot X-Terminator as “effortless.” In the press, it drops with such consistency that many competitive shooters bypass individual charge weighing in favor of high-speed volumetric throws. In the rifle, Ramshot X-Terminator is noted for its sharp, efficient ignition. It reaches peak pressure quickly, making it an excellent match for shorter barrels often found on modern tactical rifles and carbines. The recoil impulse is generally described as a “crisp snap,” providing the feedback necessary for rapid follow-up shots.
Pros & Cons
- Pros:
- Industry-leading metering accuracy in progressive and automated presses.
- Extremely clean burning, significantly reducing the interval between barrel cleanings.
- Optimized for light-to-medium weight bullets in high-velocity cartridges.
- Highly effective in straight-wall cases like the 45-70 Government.
- Cons:
- Slightly more temperature-sensitive than the Hodgdon Extreme line.
- May produce more muzzle flash than specialized low-flash propellants in very short barrels.

Temperature Stability & Burn Rate Analysis
While Ramshot X-Terminator is a double-base spherical powder—a category historically known for temperature sensitivity—it utilizes modern deterrent coatings that make it remarkably stable compared to older ball powders like Winchester 748. In technical ballistics testing, Ramshot X-Terminator has shown a total velocity spread of approximately 65 FPS across a massive 150-degree Fahrenheit range.
Specifically, between 0 degrees and 80 degrees Fahrenheit, the shift is negligible, often staying within single digits for total FPS variance. As temperatures climb above 90 degrees Fahrenheit, reloaders may see a more pronounced increase in pressure. For most varmint hunting scenarios, which occur in moderate-to-high heat, the powder remains predictable, provided the load was developed with a reasonable safety margin.
Stability Benchmark Comparison
| Powder Name | Stability Level | Tech Category |
| Ramshot X-Terminator | High | Double-Base Spherical |
| Hodgdon Benchmark | Extreme | Insensitive Extruded |
| Hodgdon H335 | Moderate | Standard Spherical |
Powder Comparison
Ramshot X-Terminator competes in the highly contested “223-class” burn rate window. It is often evaluated against both spherical and extruded alternatives.
- Accurate 2230: This is the closest sibling. Historically, Accurate 2230 and Ramshot X-Terminator were the exact same Belgian propellant sold under different labels. While current manufacturing may vary between Florida and Belgium, their load data remains virtually identical.
- Hodgdon H335: The legendary ball powder standard for 55-grain bullets. Ramshot X-Terminator is often preferred for being cleaner burning and slightly more stable across varying climates.
- Hodgdon Benchmark: An extruded competitor that offers superior temperature stability. While Benchmark is more “insensitive,” Ramshot X-Terminator wins on metering speed and ease of use in progressive loaders.
- IMR 8208 XBR: A premium extruded powder known for match-grade consistency. 8208 XBR is slightly slower in burn rate and generally better for heavier bullets, while Ramshot X-Terminator excels with the 40-55 grain projectiles.

Performance, Metering & Equipment
Metering Consistency
The fine spherical grains of Ramshot X-Terminator allow it to flow through equipment like the RCBS Uniflow Powder Measure 3 with nearly perfect accuracy. Deviations of more than 0.1 grains are rare. For high-volume reloading, this allows the user to trust their volumetric settings over long sessions. If ultra-precision is required for long-range varminting, using an RCBS MatchMaster Digital Powder Scale & Dispenser will provide kernel-level accuracy, though the physical properties of the powder make this less necessary than with traditional stick powders.
Fouling and Cleanliness
Ramshot X-Terminator is frequently praised for its “clean burning” nature. It leaves behind a minimal amount of soft, easily removable carbon residue. This is a critical technical advantage for high-volume varmint hunters who may fire 300-500 rounds in a single afternoon. Reduced fouling means accuracy is maintained throughout the day without the need for frequent field cleaning.
Recommended Cartridges and Applications
While the 223 Remington is the primary theater for Ramshot X-Terminator, its technical efficiency extends to several other specialized calibers.
| Cartridge | Primary Application |
| 223 Remington | 40-55 grain high-volume varminting |
| 222 Remington | Precision target and varmint loads |
| 17 Remington | Maximum velocity small-bore hunting |
| 204 Ruger | Flat-shooting predator control |
| 308 Winchester | Efficient light-bullet (110-125 grain) loads |
| 6.5 Grendel | Fast-burning loads for shorter barrels |
| 45-70 Government | High-velocity lever-action hunting loads |
| 6mm ARC | Competitive target and varminting |
Bullets
Ramshot X-Terminator performs optimally when paired with projectiles designed for high-velocity expansion or match-grade stability in small-capacity cases.

Primers
Consistent ignition is paramount for spherical powders to ensure uniform pressure build-up. While Ramshot X-Terminator is easy to ignite, selecting a high-quality primer will minimize extreme spreads in muzzle velocity.
- CCI No. 400: The standard small rifle primer choice for most 223 Remington loads.
- Federal GM205M: Match-grade small rifle primer for the ultimate in shot-to-shot consistency.
- CCI No. 450: A magnum small rifle primer often recommended to ensure complete ignition of dense ball powders.
- Remington 7-1-2: Known for a harder cup, making it suitable for high-pressure tactical loads.
- CCI No. 41: Military-spec primer designed to prevent slam-fires in semi-auto rifles like the AR-15.
- Winchester WSR: A high-energy small rifle primer that provides a hot flame for spherical propellants.
- Fiocchi Small Rifle Magnum: An excellent international option for ensuring ignition in colder climates.
- RWS No. 4033: Premium European primer for benchrest-level precision in the 222 Remington.
- Sellier-Bellot V361617: A reliable, consistent choice for high-volume reloading projects.
Expert Verdict
Ramshot X-Terminator remains one of the most technically sound choices for the reloader who values efficiency and cleanliness. Its unique positioning as a powder that can handle the extreme pressures of the 17 Remington while also being a top performer in the massive 45-70 Government case is a testament to its engineering. While it may not offer the extreme temperature “blanket” of some extruded powders, its superior metering and cleaning benefits make it an indispensable tool for high-volume shooters.
For those loading on progressive presses, Ramshot X-Terminator is perhaps the most “user-friendly” rifle powder on the market today.
Expert Pro Tip: When loading Ramshot X-Terminator for semi-automatic rifles like the AR-15, use a Frankford Arsenal Powder Trickler to find your initial accuracy node, then trust your volumetric measure for the bulk production. For the best accuracy results with ball powders, ensure you are utilizing a consistent neck tension of at least 0.002 inches. This prevents the bullet from shifting during the sharp ignition cycle, ensuring a uniform start to the pressure curve.
