As the name implies, this Extreme Extruded propellant was developed for precision cartridges. As such, it is ideally suited for benchrest and small varmint cartridges like the 6mm PPC, 22 PPC, 6mm BR, 223 Rem. and 222 Rem. Additionally, it performs superbly in the 204 Ruger and with light match bullets in 308 Winchester. With small, easy metering granules, competitive-shooting reloaders will love how it flows through progressive presses.
