Blackhorn 209 has been specifically designed as a high-performance, low-residue propellant for modern in-line muzzleloaders with sealed ignition systems using standard 209 shotgun primers. It's an excellent black powder cartridge propellant and is much less hygroscopic than other black powder substitutes. No anti-seize grease on breech plug threads is required when using Blackhorn 209. It's engineered to consistently shoot at higher velocities and with greater accuracy than any other muzzleloading powder. Its uniform size provides reliable and superior ballistics and unbeatable precision. It boasts extremely low residue without swabbing between shots and easy breech plug removal, cleaning up with ordinary solvents. It requires no special priming, is unaffected by temperature or humidity, and has an extended shelf life. A powder measure can be used for Blackhorn 209 - a unique feature of Blackhorn 209.
