Shooters World  AR Plus provides additional cleanliness and flash suppression for AR platforms chambered in popular bottlenecked cartridges. As with our other spherical propellants AR-Plus flows like water through a volumetric charger. Loaders will see no more than 1/10th of a grain of variation in charge weight from a powder drop. This has been tested in Dillon RCBS Lee Hornady Hollywood and Lyman chargers.
