Accurate Nitro 100 NF is a premier, fast-burning, double-base propellant specifically engineered for high-performance shotshell and handgun applications. The “NF” in its name stands for “New Formulation,” signifying a significant redesign by Western Powders (now under the Hodgdon brand) to improve upon the original Nitro 100’s physical characteristics and metering consistency. Historically, this powder was developed for the competitive clay target shooter, where it quickly became a staple for 12-gauge target loads due to its exceptionally clean-burning nature and consistent pressure curves.
In the modern reloading market, Accurate Nitro 100 NF has transitioned successfully into the handgun arena, particularly for shooters seeking low-recoil target ammunition. It occupies a space at the very top of the burn rate chart, making it one of the fastest powders available to the public. This extreme burn speed allows reloaders to achieve standard target velocities with very small charge weights, offering a high degree of economy per pound of propellant. Whether used in a classic 45 ACP target pistol or a 38 Special revolver, Accurate Nitro 100 NF provides a unique combination of high energy and physical “fluffiness” that aids in case volume occupancy.

Powder Description & Technical Profile
Accurate Nitro 100 NF is a double-base propellant, meaning it utilizes both nitrocellulose and nitroglycerin as its primary energy sources. The inclusion of nitroglycerin increases the energy density of the powder, allowing it to maintain reliable ignition and consistent burn characteristics even at the lower pressures typical of target ammunition. The physical shape of Accurate Nitro 100 NF is a flattened spherical (sometimes referred to as a “thin flake”) geometry. This specific shape was the core of the “NF” redesign, as the older version was a more traditional flake that occasionally suffered from inconsistent flow in small-diameter powder measures.
The physical density of Accurate Nitro 100 NF is relatively low, giving it a high-volume “fluffy” characteristic. This is a critical technical advantage for handgun reloaders. Cartridges like the 45 ACP and 38 Special have large internal case volumes; using a very dense, fast-burning powder can result in a tiny charge that is difficult to detect visually during a powder check. Accurate Nitro 100 NF occupies more space for its weight than many of its competitors, making it easier to identify double-charges or under-charges at the loading bench.

Technical Characteristics
The technical profile of Accurate Nitro 100 NF is defined by its ability to reach peak pressure rapidly. This makes it highly efficient in 12-gauge target shells where the shot column must be accelerated quickly within a short pressure duration.
| Feature | Specification |
| Manufacturer | Accurate (Hodgdon) |
| Powder Type | Double-Base |
| Grain Shape | Flattened Spherical / Thin Flake |
| Base Type | Nitroglycerin / Nitrocellulose |
| Relative Burn Rate Category | Ultra-Fast |
| Density (g/cc) | 0.525 – 0.550 |
| Primary Use | 12-gauge, 45 ACP, 38 Special |
The bulk density of Accurate Nitro 100 NF typically ranges around 0.525 to 0.550 g/cc. This is significantly lower than more modern spherical powders like Accurate No. 2, which often exceed 0.700 g/cc. For the reloader, this means that while Accurate Nitro 100 NF is fast, it fills the case more effectively than its chemical burn rate might suggest.
Temperature Stability & Burn Rate Analysis
In the hierarchy of propellants, Accurate Nitro 100 NF is positioned in the “fastest of the fast” category. Its burn rate is comparable to Hodgdon Clays and Alliant Bullseye. This speed is achieved through a combination of its high nitroglycerin content and a very high surface-area-to-volume ratio in the grain geometry. Because it burns so quickly, the pressure peak occurs very early in the firing cycle, usually while the projectile is still within the first few inches of the barrel.
Temperature stability for Accurate Nitro 100 NF is noteworthy for a double-base fast powder. While double-base powders are traditionally more sensitive to extreme heat than single-base powders like Hodgdon Clays, the “NF” formulation has proven to be remarkably consistent across standard competitive shooting environments. It is significantly more stable in varied temperatures than older “hot-burning” powders like Hodgdon Titegroup, which can exhibit pressure spikes in high-heat conditions. However, like all fast powders, Accurate Nitro 100 NF should be worked up carefully if the intended use is in extreme climates.
Powder Comparison
When selecting Accurate Nitro 100 NF, reloaders generally compare it against other industry standards used for target and low-pressure loads.
| Powder | Relative Burn Rate | Density | Primary Cartridges |
| Accurate Nitro 100 NF | Ultra-Fast | 0.550 | 45 ACP, 38 Special |
| Alliant Bullseye | Similar | 0.480 | 45 ACP, 9mm Luger |
| Hodgdon Titegroup | Slightly Slower | 0.730 | 9mm Luger, 40 SW |
| Hodgdon Clays | Similar | 0.420 | 12-gauge, 45 ACP |
Compared to Alliant Bullseye, Accurate Nitro 100 NF tends to burn cleaner and leave less “sooty” residue on the firearm. Against Hodgdon Titegroup, it offers a significantly better case-fill volume, which is a major safety advantage in large-capacity handgun cases. While Hodgdon Clays is often considered the benchmark for cleanliness, Accurate Nitro 100 NF often provides more consistent velocities in cartridges with larger primer-to-powder gaps due to its double-base energy.
Performance, Metering & Equipment
The “NF” formulation was specifically designed to solve the metering issues of the original Nitro 100. The new flattened spherical grains are small enough to flow through the narrow apertures of precision powder measures without bridging. When using a high-quality volumetric measure like the Lyman Brass Smith Powder Measure, Accurate Nitro 100 NF typically drops with a variance of less than 0.1 grains.
For those using progressive reloading presses such as the Dillon XL 750, the light weight of Accurate Nitro 100 NF means it is less prone to “spilling” out of the case during the indexing of the shell plate compared to heavier, more fluid spherical powders. On a single-stage press like the RCBS Rock Chucker Supreme, the “fluffy” nature of the powder makes it easy to spot discrepancies in the powder column height during a batch-loading process. It is highly recommended to use a Frankford Arsenal Powder Trickler when working at the maximum charge weight, as even a 0.2-grain overcharge can significantly increase pressure in this burn rate class.
Recommended Cartridges and Applications
While primarily a shotshell powder, Accurate Nitro 100 NF has a dedicated following in several handgun calibers where target accuracy and low recoil are the primary goals.
| Cartridge | Primary Application |
| 45 ACP | Bullseye Target & Low Recoil Plinking |
| 38 Special | Target Wadcutter & CAS Loads |
| 9mm Luger | Minor Power Factor Competition |
| 44 Special | Low-Velocity Cowboy Action |
| 12-gauge | 7/8 oz & 1 oz Clay Target Loads |
| 45-70 Government | Ultra-Light Gallery/Plinking Loads |
In the 45 ACP, Accurate Nitro 100 NF is exceptional with lead or coated semi-wadcutter bullets. It provides enough gas volume to cycle most standard recoil springs while keeping the muzzle flip to an absolute minimum. In the 38 Special, it is a top choice for 148-grain hollow-base wadcutters, providing the soft, consistent “push” required for extreme accuracy at 25 and 50 yards.
Bullets
The ultra-fast burn rate of Accurate Nitro 100 NF makes it most compatible with standard-weight or lightweight bullets for a given caliber. Heavy-for-caliber bullets should be avoided as they increase the dwell time and can lead to dangerous pressure spikes with such a fast propellant.
| Bullet Model | Weight Range | Recommended Application |
| Sierra Sports Master | 185 grain | 45 ACP Target |
| Hornady Interlock | 158 grain | 38 Special Lead SWC |
| Speer TNT | 115 grain | 9mm Luger Plinking |
| Barnes TSX | 110 grain | 357 Magnum (Low-Velocity Only) |
When loading for the 45 ACP, a 185-grain or 200-grain lead bullet is the ideal companion for Accurate Nitro 100 NF. The soft lead engages the rifling easily, and the fast powder ensures a complete burn before the bullet leaves the barrel, keeping the firearm’s internal components remarkably clean.
Primers
Because Accurate Nitro 100 NF is so easy to ignite and burns at relatively low pressures, there is rarely a need for magnum primers. Standard primers provide a more than adequate flame front for this propellant. However, consistency is key for target accuracy, so selecting a primer with a reputation for low standard deviations is paramount.
Recommended Primers for Accurate Nitro 100 NF:
- CCI 300 (Large Pistol) – The standard for 45 ACP.
- Federal 100 (Small Pistol) – Exceptional sensitivity for 38 Special revolvers.
- Winchester WSP (Small Pistol) – Versatile choice for 9mm Luger target loads.
- CCI 500 (Small Pistol) – Clean-burning and reliable for general use.
- Federal 150 (Large Pistol) – Preferred by many Bullseye competitors for its soft cup.
- Remington 9-1/2 (Large Rifle) – Only for ultra-light 45-70 Government loads.
- Sellier & Bellot V360157 (Small Pistol) – A cost-effective option for high-volume loading.
- Winchester WLP (Large Pistol) – Designed for both standard and magnum ignition; very consistent.
In the 45 ACP, the CCI 300 is often the “go-to” primer for Accurate Nitro 100 NF, as its cup hardness is well-matched to the firing pin strikes of 1911-style pistols. For 38 Special revolvers with lightened trigger pulls, the Federal 100 is the industry standard for ensuring 100 percent ignition reliability.
Conclusion & Expert Verdict
Accurate Nitro 100 NF is a testament to the idea that some of the best handgun powders actually start their lives in a shotgun shell. By prioritizing a clean burn and high energy density, Western Powders created a propellant that serves the most demanding competitive shooters in two different disciplines. While it lacks the versatility to load high-velocity magnum rounds or heavy-rifle cartridges, it is not designed for those roles. It is a specialist powder, and within its specialty – low-pressure target loads – it is arguably one of the best performers on the market.
For the reloader who values cleanliness and economy, Accurate Nitro 100 NF is difficult to beat. A single pound of this powder can produce over 1,700 rounds of 45 ACP target ammunition, assuming a 4.0-grain charge. This level of efficiency, combined with the safety benefit of its high-volume grain structure, makes it a top-tier choice for both novice and expert handloaders. If your goal is a soft-shooting, accurate, and clean-running firearm, Accurate Nitro 100 NF should be a permanent fixture on your reloading bench.
Expert Pro Tip: When loading Accurate Nitro 100 NF for the 45 ACP, pay close attention to your crimp. Because this powder is so fast, the bullet starts moving almost instantly upon ignition. A consistent taper crimp of 0.469-0.471 inches ensures that the bullet is held firmly enough to allow for uniform pressure build-up before the bullet releases from the case mouth, which is the secret to achieving single-digit velocity standard deviations.
