Powder Description & Technical Profile
Alliant Reloder TS 11 is a modern, extruded powder featuring a single-base composition. The “TS” designation stands for Temperature Stable, highlighting the core engineering philosophy behind its development. Unlike older propellant designs that may experience significant pressure spikes in high heat or velocity drops in the cold, Alliant Reloder TS 11 utilizes advanced decoppering additives to maintain barrel cleanliness while providing a remarkably flat temperature-to-velocity curve.
The physical geometry consists of small, uniform kernels. This specific grain size is intentional, designed to bridge the gap between the high energy of larger extruded powders and the easy flow of spherical powders. In terms of the expert “feel,” shooters often describe the pressure curve of Alliant Reloder TS 11 as a progressive push rather than a sharp spike, allowing for high muzzle velocities without reaching the overpressure thresholds too early in the load development process.
Pros & Cons
- Pro: Industry-leading thermal stability ensures your zero remains constant in all seasons.
- Pro: Integrated decoppering agent reduces maintenance intervals and preserves accuracy.
- Pro: Optimized for high-density loads in 223 Remington and 6mm ARC.
- Con: As a specialized extruded grain, it may require a trickler for the most precise charge weights.
- Con: Availability can be limited due to high demand in the precision community.
Technical Characteristics

| Burn Rate Category | Medium-Fast Rifle |
| Shape | Small Extruded Stick |
| Coating | Graphite with Decoppering Additive |
Temperature Stability & Burn Rate Analysis
The primary market position of Alliant Reloder TS 11 is to compete directly with the “Extreme” line of propellants. In internal testing and reloader consensus, Alliant Reloder TS 11 exhibits a variation of less than 0.5 FPS per degree Fahrenheit. This level of stability is crucial when a match starts in the cool morning and ends in the midday sun.
Stability Table
| Powder | Stability Rating | Sensitivity (FPS Variation) |
| Alliant Reloder TS 11 | Ultra-Stable | 0.3-0.5 FPS per Degree |
| Hodgdon Varget | Stable | 0.5-0.8 FPS per Degree |
| Alliant Reloder 15 | Sensitive | 1.2-1.8 FPS per Degree |
Powder Comparison
To understand where Alliant Reloder TS 11 fits, it must be compared against its most frequent competitors. It sits in a “sweet spot” for small-to-medium cases where Hodgdon Varget might be too slow and Hodgdon H322 too fast.
| Powder | Burn Rate | Density | Primary Cartridges |
| Hodgdon H322 | Faster | 0.895 | 223 Remington, 6mm PPC |
| Benchmark | Slightly Faster | 0.910 | 223 Remington, 204 Ruger |
| Alliant Reloder TS 11 | Subject | 0.940 | 223 Remington, 6mm ARC |
| Hodgdon Varget | Slower | 0.865 | 308 Winchester, 6.5 Creedmoor |
| Alliant Reloder 15 | Slower | 0.935 | 308 Winchester, 22-250 Remington |
Performance, Metering & Equipment
While Alliant Reloder TS 11 is an extruded powder, its kernel size is specifically miniaturized to improve metering. In high-volume progressive presses, it maintains a consistency of +/- 0.1 grains, which is exceptional for a stick powder. However, for maximum precision, using a high-end scale like the RCBS Chargemaster Lite or the Lyman Gen6 Compact Powder System is recommended.
Fouling with Alliant Reloder TS 11 is noticeably lower than legacy propellants. The decoppering agent works by chemically reacting with copper residue in the bore, preventing the buildup of “copper wash” that can degrade accuracy over a long string of fire. This makes it an ideal choice for high-volume varmint hunters who do not want to clean their rifles every 20 rounds.
Recommended Cartridges and Applications
Alliant Reloder TS 11 excels in cartridges with a high expansion ratio or those used in AR-15 platforms where port pressure is a concern.
| Cartridge | Primary Application |
| 223 Remington | Service Rifle & Varmint Hunting |
| 224 Valkyrie | Long Range Precision |
| 6mm ARC | Precision Rifle Series (PRS) |
| 22-250 Remington | High Velocity Varmint |
| 30-30 Winchester | Lever Action Hunting |
Bullets
The burn rate of Alliant Reloder TS 11 is optimized for mid-to-heavyweight bullets in small-bore calibers.
| Bullet Manufacturer | Model | Recommended Weight |
| Sierra Bullets | MatchKing | 69-77 Grains |
| Hornady | ELD Match | 73-88 Grains |
| Nosler | Custom Competition | 69-77 Grains |
| Berger Bullets | VLD Target | 70-80 Grains |

Expert Verdict
Alliant Reloder TS 11 represents the next generation of propellant technology. By combining the legendary energy of the Alliant Reloder series with modern temperature stability and decoppering additives, it provides a versatile solution for the modern marksman. Whether you are competing in a PRS gas-gun division or hunting coyotes in the freezing winter, Alliant Reloder TS 11 delivers the peace of mind that your point of impact will remain true.
Expert Pro Tip: When loading Alliant Reloder TS 11 in high-density cases like the 223 Remington with 77-grain bullets, use a long drop tube to settle the kernels. This allows for a more consistent case fill and prevents the compression from affecting bullet seating depth or neck tension.
