This spherical propellant is designed expressly for the 300 Remington AAC Blackout cartridge and meters very accurately.

CFE BLK contains our Copper Fouling Eraser ingredient, originally used in military propellant, which greatly deters copper fouling and contributes to longer periods of top accuracy with less barrel cleaning time.

It provides full function in modern sporting rifles throughout a range of bullet weights and is perfect for subsonic loads. In addition to being outstanding in the 300 Blackout, it performs well in many smaller capacity cartridges such as the 17 Hornet, 17 Ackley Hornet, 218 Bee, 221 Fireball and many more. It also yields top performance in the 6.8 Remington SPC and the 7.62X39 mm Russian cartridge.
