The most accurate Uniflow ever made.
The RCBS Uniflow-III Powder Measure sets a new standard for precision in reloading. Engineered with exacting tight tolerances, it delivers consistently accurate charges—reload after reload—without the risk of clogging or overcharges. Its redesigned measuring system allows one metering cylinder and rotor to throw charges for both rifle and pistol, covering a wide range from 0.5 to 95 grains with 0.1–0.3 grain accuracy.

The NG-resistant, anti-static hopper holds up to half a pound of extruded powder or a third of a pound of flake powder, and its threaded design makes disassembly fast and simple for easy cleaning. Whether you’re loading precision rifle rounds or handgun cartridges, the Uniflow III is the most reliable, versatile, and accurate powder measure RCBS has ever built.

Note: Always use with a reliable powder scale to set and periodically check charges. Not for use with black powder.
