For any type of reloading project, Hodgdon Powder has the broadest assortment of high-quality smokeless propellants available.
Since its origin, the Hodgdon H4198 Extreme Extruded propellant has undergone a few modifications, but it has always managed to keep its crucial burning speed the same as it was in the past. The kernels were trimmed so that the metering would be more accurate, and the appropriate ingredients were added so that it would be particularly insensitive to hot and cold conditions. Hodgdon H4198 performs exceptionally well with a variety of cartridges, including the 222 Remington, 444 Marlin, and 7.62 x 39.
Caution: The loads that are listed in the reloaders guide should not be exceeded at any time while using smokeless powder.
Never, ever mix any powders, regardless of the type, brand, or origin of any powder.
Never attempt to use smokeless powder as a substitute for black powder or any other form of black powder alternative.
