Just as the name implies Hodgdon Extreme Benchmark Rifle Powder is an extruded propellant designed to deliver precision when reloading cartridges. This powder is the ideal choice for benchrest as well as small varmint cartridges including the 6mm BR .223 Remington 6mm PPC and .22 PPC; it also offers outstanding performance for the .204 Ruger and .308 Winchester with light match bullets.Metering is easy because of the small granules and due to the way the powder flows through progressive presses it has become a preferred option for serious competitive shooters.
