If you like doing your own reloading with your traditional magnums like the 357 Mag and 44 Remington Mag, Accurate No. 9 is the powder for you. It has fantastic metering, exceptional accuracy, and phenomenal economy per load. This powder performs remarkably well in the 357 Sig and 10mm Auto, but can also be used in larger magnums like the 460 and 500 S&W. Accurate No. 9 is a clean burner, and one of the most economic powders out there.
