High density, double base, ball propellant similar to Accurate No. 9 is most suitable for .44 Magnum. This propellant gives excellent velocities for the pressures generated and with less flash than other comparable powders. It is intended for use in large capacity handgun cartridges (.357, .41, .44 Magnum and .454 Casull). It is also suitable for some small rifle cartridges (.25-20 Winchester, .30 M1 Carbine) and the .410 shotgun. It is the best with heavier bullets in most calibers.
