The RCBS quick change powder measure offers the ability to go from light pistol to magnum rifle charges quickly. The QCPM features metering assemblies that change out with the pull of a pin. Extra metering assemblies can be purchased to have them preset for your favorite smokeless powder charges. The drain attachment empties the powder hopper without the need to remove it from the stand or press. The quick change parts can be used to upgrade uniflow powder measures to this system.
