The RCBS Uniflow Powder Measure is constructed from iron and steel, it consistently throws accurate charges from 5 grains of Bullseye to 110 grains of 4350 load after load. Ball, Flake and extruded powder pours uniformly from the cylinder into the brass, eliminating the hazards of overloads caused by clogging and charges are easily changed without emptying the powder hopper. There is a numbered measuring screw for reference to find a given charge at a later date. The precision ground surfaces of the measuring cylinder allow it to fit precisely into the honed main casting. The included stand plate is drilled for mounting to a reloading bench or to a press under a reloading die lock ring. The RCBS Uniflow Powder Measure is compatible with standard powder stands. The measure also feature standard 7/8"-14 threads that will fit powder through expanding dies and presses that feature standard threads. Two powder drops tubes for 22 caliber and up are included.
