This new spherical propellant was designed expressly for the 300 Remington AAC Blackout cartridge. It provides full function of AR type rifles throughout the range of bullet weights, and is perfect for those sub-sonic reduced loads. In addition to being outstanding in the 300 Blackout, it performs beautifully in many smaller capacity cartridges, in particular, varmint specials 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. 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!
