The RCBS Uniflow Powder Measure III is a precision reloading tool built for handloaders who demand consistency across every single round. If you're loading rifle or pistol ammunition and tired of worrying whether your powder charges are truly uniform, this metering device cuts through the variables with tight manufacturing tolerances and a design that eliminates common dispensing errors. The Uniflow III represents RCBS's most refined take on their proven Uniflow platform—faster setup, easier cleanup, and most importantly, charge-to-charge repeatability that lets you focus on making ammunition rather than second-guessing your measure.
What sets the Uniflow III apart is its flexibility and build quality. A single metering cylinder and rotor handle everything from light pistol loads (as low as 0.5 grains) all the way up to heavy rifle charges (up to 95 grains), so you don't need multiple measures sitting on your bench. Switching between different powder types or charge weights on the same powder is quick—no need to empty the hopper each time. The NG-resistant anti-static hopper threads on and off for painless cleaning, and it's sized to hold half a pound of extruded powder or one-third pound of flake powder, so you'll load longer between refills.
Accuracy matters in reloading, and the Uniflow III backs up its claims with precision-machined reference surfaces and tolerances tight enough to deliver 0.1 to 0.3 grain consistency. That said, like any quality powder measure, it works best paired with an accurate powder scale for your initial setup and periodic checks during a loading session. This measure is not suitable for black powder.
| Measure Range | 0.5–95 grains |
| Accuracy | 0.1–0.3 grain |
| Hopper Material | NG-resistant anti-static |
| Hopper Capacity (Extruded Powder) | 0.5 lb |
| Hopper Capacity (Flake Powder) | 0.33 lb |
| Hopper Design | Threaded for quick removal and cleaning |
| Compatibility | Not for use with black powder |
Yes. One metering cylinder and rotor handle the full range from 0.5 grains (light pistol loads) to 95 grains (heavy rifle charges), so you don't need separate measures for different cartridges.
If you're staying with the same powder type but switching charge weights, you can change the measure without emptying the hopper. When moving to a different powder, you'll want to empty it first to avoid mixing.
The measure delivers 0.1 to 0.3 grain consistency across charges. RCBS recommends using it with an accurate powder scale to set your initial charge and to spot-check charges periodically during a loading run, which is standard best practice for any reloading setup.
No. The Uniflow III is not designed for black powder reloading.
