Accurate 11FS

Accurate 11FS

Accurate 11FS is a double-base, flash-suppressed spherical powder designed to deliver full-power performance in magnum handguns and select small-capacity rifle cartridges. Developed with tactical and defensive shooters in mind, this high-energy propellant incorporates a flash suppressant that dramatically reduces muzzle signature in low-light conditions. This makes it especially useful in personal defense situations, where preserving night vision can be the difference between target acquisition and hesitation. It’s an ideal choice for concealed carry loads, home defense, or low-light competitive stages.

In magnum handgun cartridges like .357 Magnum, .41 Magnum, and .44 Magnum, Accurate 11FS delivers exceptional velocity with consistent pressure curves. This makes it well-suited for reloaders aiming to produce hard-hitting, clean-burning rounds with tight standard deviations. Whether you’re shooting a large-frame revolver for hunting or personal defense, 11FS ensures excellent terminal performance and reliability. It also provides full case fill and reliable ignition, key factors in maintaining uniformity in high-powered pistol loads.

What sets Accurate 11FS apart is its excellent performance in modern rifle cartridges such as the .300 AAC Blackout. When paired with lighter bullets, 11FS generates impressive velocities while maintaining pressure control—helping maximize downrange performance. For reloaders seeking top-tier ballistic results in .300 BLK platforms, especially when using super-sonic projectiles, this powder is a standout option. It cycles reliably in semi-automatic platforms while offering improved flash control and consistent velocities across temperature ranges.

The spherical grain structure of Accurate 11FS ensures smooth metering, making it perfect for progressive reloading presses. Its versatility across handgun and rifle platforms gives reloaders the freedom to streamline their bench setups without sacrificing performance or consistency. Made in the USA, Accurate 11FS stands out as a powerful and practical powder for a wide range of shooting needs.

Available in 1 lb. and 8 lb. containers.
