The RCBS Little Dandy Powder Rotor #1 (part number 86001) is a fixed-volume metering rotor built for the RCBS Little Dandy Powder Measure, a hand- or bench-operated tool that throws precise smokeless-powder charges by volume rather than by weight. Each of the 28 available rotor numbers meters a different fixed volume, and rotor #1 is one of those interchangeable sizes. Reloaders who load the same recipe over and over rely on a dedicated rotor like this one to skip re-adjusting a powder measure between range sessions. It drops straight into any Little Dandy body without tools.

Key Specifications

• interchangeable with all 28 Little Dandy rotor sizes so it drops into any Little Dandy Powder Measure body without modification.
• meters powder strictly by volume, not by weight giving repeatable charges once a rotor is matched to a load.
• built exclusively for the RCBS Little Dandy Powder Measure and is not a fit for other RCBS or competitor powder measures.
• requires no re-calibration when swapped in or out so changing loads is as fast as changing rotors.
• compatible with standard smokeless reloading powders covering the propellants most bench and progressive reloaders already stock.
• ships at approximately 0.3 lb light enough that a full set stores easily in a range bag or bench drawer.

Frequently Asked Questions

What does the rotor number mean? Each Little Dandy rotor is a fixed metering volume; RCBS publishes a rotor chart matching each numbered rotor to specific powder/charge combinations, so confirm rotor #1 against that chart for your intended load before loading.

Will this rotor fit my Little Dandy Powder Measure? Yes. All 28 Little Dandy rotor sizes, including #1, are interchangeable in every Little Dandy Powder Measure body RCBS has produced.
