Every single container of Alliant Smokeless Powder is supported by a century’s worth of manufacturing knowledge as well as the most stringent quality control techniques that are currently available on the market. In a ballistics laboratory, the material’s chemical composition, grain shape and size, and overall density are subjected to ongoing testing and inspection. This helps ensure the material’s uniformity.
There is a new powder option available on the market called AR-Comp from Alliant Powder. This powder may be used for reloading AR-style rifles as well as other types of rifles. Alliant AR Comp, manufactured by Alliant, is the perfect powder for individuals who enjoy shooting classic rifles in addition to those who engage in fast-action, high-volume AR shooting. Alliant AR Comp is an ignition system that was designed exclusively for AR-style rifles and works very well with heavy 223 and 308 competition bullets. It provides high performance ignition each and every time.
Do not go above the loads listed in the reloaders guide.
Mixing two powders, regardless of type, brand, or source, is never a good idea.
Never substitute any smokeless powder for black powder or any substitute for black powder.
