This Extreme Extruded propellant has gone through some changes since
its inception, all the time maintaining the same important burning speed of the past. The
kernels were shortened for improved metering and necessary elements were added to make
it extremely insensitive to hot/cold temperatures. H4198 is outstanding in cartridges like the
222 Remington, 444 Marlin and 7.62 x 39.
