Hodgdon - H4831
H4831 is an extruded powder in Hodgdon’s Extreme series and 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 supplier 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 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.
