RCBS ChargeMaster Supreme Digital Powder Scale and Dispenser - Precision Reloading Tool

The RCBS ChargeMaster Supreme is a digital powder scale and dispenser built for reloaders who want speed without sacrificing accuracy. If you're tired of slow, finicky powder measures or the tedium of hand-weighing every charge, this combination unit handles both functions—and does it fast. It measures powder to 0.1-grain precision, dispenses at up to two grains per second, and connects to your phone via Bluetooth so you can monitor and control charges from the app. It's the kind of upgrade that transforms your loading bench from a chore into something you actually look forward to.

What sets the ChargeMaster Supreme apart is the proprietary Powder Learn Process, which learns your specific powder's flow characteristics and adjusts dispensing on the fly to hit your target charge weight consistently. The 16-segment LCD touchscreen is responsive and clear, the 1500-grain load cell capacity handles most rifle and shotgun loads, and the 50 memory slots let you store your favorite recipes. A powder hopper drain alarm (patent pending) gives you a heads-up before you run dry mid-session, and you can disable the beep if you're reloading in a shared space. An optional external battery pack is available if you want to unplug from the bench entirely.

Reloaders often debate speed versus precision—the ChargeMaster Supreme is one of the few tools that doesn't force you to choose. Whether you're volume-loading for competition, fine-tuning hunting rounds, or experimenting with new loads, this scale-dispenser combo handles the math and the grunt work, so you can focus on consistency and technique.
