CFE BLK Powder — Burn Rate, Substitutes & Typical Cartridges

About this powder

CFE BLK was purpose-built for the .300 Blackout cartridge, a round that spans a wide range of bullet weights and velocities from 220-gr subsonic to 110-gr supersonic. CFE BLK handles both ends of that spectrum reliably while reducing copper fouling — making it ideal for suppressed .300 BLK builds.
