Accurate No. 9 Smokeless Gun Powder

Accurate No. 9 (often labeled as AA 9) is a high-energy, double-base 9 powder designed for reloaders who demand superior performance in magnum pistol and heavy revolver cartridges (9 powder​). As part of the Accurate Powders family, this propellant offers consistent ignition, predictable pressure curves, and reliable velocities, making it ideal for competitive shooters, hunters, and handgun enthusiasts alike.

Known for its versatility, Accurate No. 9 delivers top velocities while maintaining safe pressures across a wide range of high-performance handgun cartridges, including .357 Magnum, .41 Magnum, and 10mm Auto. It’s also an excellent option for 300 9 subsonic loads, where controlled burn rates and clean combustion are essential for smooth cycling and consistent accuracy. Its fine-grain spherical design ensures superb metering, which is particularly valuable when loading on progressive presses for high-volume production.

For reloaders practicing accurate reloading techniques, the benefits of AA 9 are clear: consistent lot-to-lot performance, easy flow through powder measures, and dependable ignition even under varied environmental conditions. Accurate No. 9 also excels in maintaining uniform velocities across temperature ranges, which helps maintain point-of-impact consistency — a crucial factor for precision pistol and carbine shooters.

While 4350 powder is often discussed in the context of mid-to-large rifle cartridges, it’s helpful to recognize how these two powders occupy different performance niches. Accurate No. 9 is optimized for magnum handgun and some specialty carbine loads, whereas 4350 caters to larger case capacities and slower burn requirements. Understanding burn rate relationships allows reloaders to make informed powder selections based on bullet weight, case volume, and pressure goals.

Safety remains paramount: always refer to published load data for AA 9 or Accurate No. 9 before beginning any reloading project. Start at recommended minimums and work up carefully, observing pressure signs as you go. Consistency in components—brass, primers, and bullet seating depth—will help maximize the inherent precision of this powder.

In summary, Accurate No. 9 is a high-performance 9 powder that bridges power and precision. Whether you’re loading magnum revolvers, subsonic 300 9 rounds, or full-power pistol cartridges, AA 9 offers the reliability, accuracy, and clean burn that define a professional-grade accurate reloading experience.
