CFE BLK is a new Spherical powder from Hodgdon, specifically formulated for the 300 AAC Blackout cartridge. This new powder provides full function of AR-type rifles throughout the range of bullet weights, and is perfect for those subsonic reduced loads. In addition to being the perfect solution for the .300 Blackout, it performs beautifully in many smaller capacity cartridges, in particular, varmint 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 7.62X39mm Russian cartridge. This fine powder meters like a dream and leaves no copper residue, extending accuracy for longer shooting periods, and making clean-up quick and easy. It is truly a remarkable new propellant!
