The RCBS ChargeMaster Supreme takes everything RCBS learned from decades of building powder dispensers and rolls it into a single bench unit that handles the measuring step for you. It reads to 0.1-grain accuracy off a medical-grade load cell, stores up to 50 charge recipes, and keeps a 1,500-grain load cell capacity so you can run through a loading session without constantly topping off the hopper. Set your charge weight on the 16-segment LCD touchscreen, hit go, and let it do the work.
The standout here is the proprietary Powder Learn Process. Instead of dispensing every powder the same way, the Supreme throws a few test charges, figures out how your specific propellant flows through the tube, and then dials in its dispensing to that behavior. The payoff is speed. Reloaders running it report it will drop a charge in under 10 seconds once Powder Learn finishes, and it handles stick powders especially well. It's a genuine step up from the old ChargeMaster 1500 in both pace and consistency.
Bluetooth connectivity pairs the dispenser with the free RCBS app on your phone or tablet, so you can watch powder readouts, auto-dispense, and control the charge without leaning over the unit. It's a nice touch when you've got a progressive rhythm going. You can also disable the audible beep if you'd rather load in quiet.
Little details show RCBS thought this one through. There's a patent-pending powder hopper drain alarm so you don't walk away with the drain open and dump propellant on the floor, plus a side drain spout for quick powder swaps between loads. The CE-approved universal power supply runs on multiple voltages, and an optional external battery pack adds portability if you want to take it away from the bench. For precision rifle work in calibers like 308 Winchester, 6.5 Creedmoor, and 30-06 Springfield, this is one of the most capable dispensers in its class.
It's rated to +/- 0.1-grain accuracy using a medical-grade load cell. Reloaders checking charges against lab-grade balances consistently confirm it holds that spec once the unit is warmed up and calibrated. For most precision rifle and handgun loading, that's right where you want to be.
Powder Learn throws a series of test charges so the dispenser can learn how your specific powder flows through the tube, then optimizes its dispensing speed to match. The result is faster, more consistent charges, often dropping a load in under 10 seconds. It noticeably improves first-charge accuracy compared to running the default profile.
It handles stick and extruded powders especially well and runs smoothly across common propellants. Very fine ball powders can be trickier to meter precisely, which is true of most electronic dispensers, so some reloaders verify those charges or trickle the last bit. Running Powder Learn for each propellant helps it adapt to whatever you're using.
No, the app is optional. You can run the ChargeMaster Supreme entirely from the 16-segment LCD touchscreen on the unit itself. The Bluetooth app just adds remote monitoring and control, and yes, the audible beep can be disabled if you prefer to work quietly.
