This accurate-metering, extruded rigle powder has super-short grains designed expressly for match, varmint, and AR-style sniper rifle cartridges. Ideally suited for .223 Remington/5.56mm NATO, .308 Winchester/7.62mm NATO, and 6mm PPC. IMR 8208 XBR is insensitive to temperature change to deliver max velocities and tack driving accuracy. Clearly the choice for competition and the varmint hunter's dream powder.
