Hodgdon Powder, H322 – 8 lbs
This Extreme series powder has likely won more benchrest matches than all other propellants combined. H322 provides match-grade accuracy in small- and medium-capacity cartridges like the 223 Remington, 6mm PPC and the 7mm TCU. As a fine extruded powder, it flows through powder measures with superb accuracy. Check your reloading manual or go to a powder manufactures website for load data.
