Hodgdon CFE BLK powder was purpose-built for subsonic 300 AAC Blackout ammunition and has since proven effective across a family of intermediate cartridges demanding clean ignition, consistent metering, and fouling mitigation. CFE BLK is a spherical propellant incorporating Hodgdon’s Copper Fouling Eraser formula, which chemically inhibits copper deposition in the bore. The spherical geometry flows freely through powder measures, reducing charge-weight variation during high-volume handloading sessions. For reloaders building subsonic 300 Blackout, 17 Hornet, 221 Fireball, 6.8 Remington SPC, or 7.62x39mm rounds, CFE BLK delivers repeatable velocities with minimal flash signature.
Load Profile
CFE BLK is optimized for cartridges operating in the intermediate pressure window — roughly 40,000 to 55,000 psi — where subsonic and moderate-velocity loads benefit from progressive burn characteristics. In 300 Blackout, charge weights typically range from 9.0 to 11.5 grains under 220-grain subsonic bullets, yielding velocities between 950 and 1,050 fps from a 16-inch barrel. The powder’s spherical shape and density allow precise metering in progressive presses, critical when assembling match-grade or suppressed ammunition where consistency directly impacts point-of-impact repeatability. Hodgdon publishes load data in the annual reloading manual and online at hodgdonreloading.com; always cross-reference published min/max charges before working up loads.

CFE BLK is sold in 1-pound and 8-pound canisters; HazMat shipping fees apply to all orders containing smokeless powder. Review our gun powder category for compatible primers, brass, and projectiles.
Safe Handling & Compliance
Smokeless powder is classified as a flammable solid (UN 0161 or UN 0509) and must be stored in a cool, dry location away from heat sources, open flame, and incompatible materials. Federal law does not restrict powder purchases to licensed dealers, but many states impose quantity limits, storage requirements, or sales-tax exemptions for reloading components — verify current state and local regulations before ordering. All powder sales are final; Tatted Tacticals ships via ground service only, and HazMat fees are non-refundable.
- Never exceed maximum published charges — consult Hodgdon’s current load data for your specific cartridge, bullet weight, primer, and case combination.
- Never mix powders — CFE BLK must not be combined with any other propellant, regardless of brand or type.
- Store powder in original containers with intact labels — lot numbers and manufacturing dates are critical for traceability and safety recalls.
