Varget is an extruded propellant in the Hodgdon line of Extreme series of powders. Varget features small, extruded grains for uniform metering, is insensitive to hot and cold temperatures and produces higher energy for improved velocities over other powders in its burning-speed class.

H4831SC is an extremely extruded powder that is an identical replica of H4831 in terms of ballistics. Because of its smaller grain size, it was given the label "SC" for "short cut." The shorter, more compact kernels allow the powder to flow more freely through the powder measures, reducing the need for granule cutting. More consistent charge weights result from the smoother flow characteristics, whereas individual grains orient more compactly, resulting in higher loading density.

This was an unnamed spherical rifle propellant when Bruce “B.E.” Hodgdon first used it.

All other propellants together have likely lost to this Extreme series powder.
