Accurate No. 11FS is a fast-burning, double-base spherical propellant developed specifically for full-power loads in magnum handguns and smaller-capacity rifle cartridges. Tailored for self-defense and tactical applications, this high-performance powder includes a flash suppressant that significantly reduces visible muzzle flash-particularly critical in low-light scenarios. Optimized for use in .300 AAC Blackout, No. 11FS delivers exceptional velocities with lighter bullets, making it a top-tier choice for shooters looking to stretch effective range and energy retention. Proudly made in the USA, this propellant provides consistent ignition, clean burn characteristics and premium performance for modern defensive and sporting loads.
