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.
H1000 is perfect for highly overbored cartridges like the 7mm Remington Magnum, 7mm STW and 30-378 Weatherby. Great heavy bullet performance in cartridges such as 6mm-284, 257 Weatherby and 270 Winchester.
