Revolutionary Blackhorn 209 propellant is redefining the term accuracy in muzzleloaders. When used as directed, this high-performance powder consistently shoots with higher velocities and greater accuracy than other propellants. It's engineered to eliminate swabbing and cleaning between shots. When compared with volume equivalents, Blackhorn 209 is ballistically superior to other muzzleloading propellants. Blackhorn 209 has the industry's lowest standard deviations and a low pressure-to-velocity ratio for precise performance every time. Blackhorn 209 is recommended for high-performance muzzleloaders with 209 primer ignition systems where the primer is TOTALLY enclosed. Not for use with any special muzzleloading primers, #11, musket or high-powered rifle primers. This powder is not suitable for sidelock muzzleloaders. Unaffected by changes in humidity or temperature. Cleans with regular centerfire or shotgun solvents. Per 10-oz. bottle.
