Shooters have been familiar with the Hodgdon H4350 Extreme Extruded propellant and its blazing speed for a number of years. During that time period, Hodgdon has modernized H4350 powder by reducing the size of the grains to make metering it easier and by rendering it immune to the effects of extreme hot and cold conditions. Within the WSM family of calibers, the H4350 is the best option (270, 7mm, 30, 325).H4350 powder is the common component used in a wide variety of cartridges, including the 243 Winchester, the 6mm Remington, the 270 Winchester, the 338 Winchester Magnum, and many more. It is unrivaled in performance for magnums firing bullets of light to moderate weight.
The Extreme line of powders was developed with high-volume shooters in mind; they feature a powder that meters exceptionally well with auto-disk type powder measures, allowing for maximum performance and precision. The innovation was made to provide the high-volume shooter an edge in the market. These spherical propellants are more efficient because they produce consistent speed and pressure, move smoothly through their operations, and are easy to measure.
Smokeless Powder Cautionary Note:
Never shoot higher than what is recommended in the reloading manual.
Do not combine powders of different brands or origins.
Always use Black Powder or a Black Powder replacement, and never any smokeless powder.
