Compared to my previous experiences with less refined dispensers that would drift or develop mechanical quirks, this RCBS unit represents a significant leap forward in reliability and user experience. Its performance consistently matches or exceeds my expectations for a device in its class.

First Use Experience

I set up the RCBS Chargemaster Supreme Electronic Powder Dispenser on my main workbench, dedicating a clean, stable surface for its operation. Initial testing involved standard Hodgdon Varget, a popular extruded rifle powder known for its metering characteristics. The unit warmed up quickly, and the initial charges were dispensed with impressive speed and accuracy, consistently landing within +/- 0.1 grains of my target. I then moved to a finer ball powder, Alliant Unique, which metered even faster and with tighter consistency.

The Bluetooth connectivity and accompanying app were straightforward to pair, offering a convenient way to manage multiple powder profiles. I found myself creating profiles for each of my frequently loaded cartridges, saving precious time during longer loading sessions. The audible beep that signals the completion of a charge can be disabled, a feature I appreciated during late-night loading sessions. The patent-pending powder hopper drain alarm is a thoughtful addition, providing an audible alert should the hopper be accidentally tipped or emptied.

Extended Use & Reliability

Over several months, the RCBS Chargemaster Supreme Electronic Powder Dispenser has become an indispensable part of my reloading process. I’ve loaded hundreds, if not thousands, of rounds with it, and its accuracy has remained remarkably consistent. The proprietary Powder Learn Process, which calibrates the unit to the specific density and flow of different powders, is particularly effective. It genuinely seemed to improve the dispensing of some more challenging extruded powders after running this process.

The unit’s housing feels solid, and the dispensing mechanism operates smoothly. I have not encountered any sticky situations or significant powder spills, thanks in part to the well-designed hopper and tray. Cleaning is simple; a quick wipe-down of the tray and a brush through the dispensing chute is usually sufficient. The scale’s sensitivity has not diminished, and it continues to provide precise readings with each operation. This reliable performance has greatly enhanced my reloading efficiency and confidence in my handloads.
