Hodgdon Powder offers one of the largest selections of quality smokeless propellants for rifle reloading. These powders are very popular with high power and long-range shooters, varmint hunters, and benchrest shooters.
Hodgdon's exclusive line of extruded rifle powders was developed to give shooters consistent performance load after load, in ever the most extreme heat and cold.
H4198 is outstanding in cartridges like the 222 Remington, 444 Marlin, and the 7.62x39.
