This double-base spherical propellant was developed with an eye toward personal defense and incorporates a flash-suppressant that substantially reduces muzzle signature in low light conditions. In the .300 Blackout, No. 11FS is capable of extremely high velocities with lighter bullets, making it the best propellant choice for shooters looking to maximize downrange performance Firearms, trailers, and some accessories are only available for purchase in stores.
