An extruded powder in Hodgdon’s Extreme series, it is probably safe to say more big-game animals have been taken by handloaders with H4831 than any other powder.
Bruce “B.E.” Hodgdon was the first to introduce this popular propellant in 1950 and, since that time, it has become a favorite for cartridges like the 270 Winchester, 25-06 Remington, 280 Remington and 300 Winchester Magnum.
For H4831SC, this Extreme extruded powder is the exact ballistic copy of H4831. Physically, it has a shorter grain size which earned it the “SC” designation for “short cut.” The shorter, more compact kernels allow the powder to flow through the powder measures more smoothly, helping to alleviate the constant cutting of granules. With the smoother flow characteristics comes more uniform charge weights, while the individual grains orient more compactly, creating better loading density.
As an Extreme extruded propellant, it shares the fine quality of insensitivity to hot and cold temperatures, as well as superb uniformity from lot to lot.
