The Uniflow-III Powder Measure is the pinnacle of accuracy from RCBS. This innovative tool ensures consistently precise powder charges with every use. Thanks to its exacting tolerances, powder flows smoothly from the measuring cylinder into the case, eliminating the risks of overloading due to clogs. What's more, the UPM-III allows for seamless transitions between different charges of the same powder without the need to empty the hopper. The NG resistant, anti-static threaded hopper is designed for easy handling and maintenance. It can hold up to half a pound of extruded powder or one-third pound of flake powder. A standout feature of the UPM-III is its versatility: one metering cylinder and rotor can handle charges ranging from 0.5 grains to 95 grains, suitable for both rifle and pistol. Cleaning is a breeze, thanks to the threaded hopper that allows for quick disassembly. Please note that the UPM-III should always be used with an accurate powder scale for initial charge settings and periodic checks during use. It is not compatible with Black Powder.
