No. 11FS is intended for full-power loads in magnum handguns and smaller capacity rifle cartridges. 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.
Warnings from the Manufacturer:
- Do not exceed the loads displayed in the reloaders guide.
- Never mix any two powders regardless of type, brand, or source.
- Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
