Description
The RCBS MatchMaster is the top of the RCBS electronic dispenser lineup, and it earns that spot by being both fast and seriously precise. The heart of it is a patent-pending dual-tube system: a large tube does the heavy lifting to get you close, then a small tube trickles in the final kernels for a dialed-in charge. In Standard Mode most charges drop in under 20 seconds with 0.10-grain accuracy, and in Match Mode the pharmaceutical-grade strain-gauge scale tightens that down to 0.04 grains, which is roughly one or two kernels of an extruded powder like H4350.
What Sets the MatchMaster Apart at the Bench
Speed is the headline here. A single MatchMaster in Standard Mode can keep pace with three ChargeMaster units, and a tuned setup will throw 38.5 grains of H4350 in under 7 seconds in Match Mode. Four programmable dispense speeds let you match the behavior of flake, ball, or extruded powders, so you can shave time off a session without sacrificing consistency. Independent testing against lab-grade analytical scales has repeatedly confirmed the unit holds tight, with standard deviations well under its advertised spec and minimal drift.
Dialing In the MatchMaster for Your Loads
The touch-screen interface keeps setup simple. You set your target weight and let the machine run. The Bluetooth app expands things further: it carries pre-configured powder profiles, lets you fine-tune each tube's behavior with sliders, stores load data including photos of group sizes and velocities, and can manage up to 8 units at once if you ever expand your bench. The improved quick-drain feature uses a flexible tube to empty the 1lb hopper from the bottom, so swapping between powders is quick and you avoid cross-contamination between batches.
For long-range and competition handloaders, consistent powder charges are the single biggest lever over group size, and the MatchMaster removes most of the human error from that step. It's a reliable, repeatable workhorse for anyone chasing match-grade loads.

Frequently Asked Questions
How accurate is the RCBS MatchMaster in Match Mode?
RCBS rates the MatchMaster at 0.04-grain accuracy in Match Mode and 0.10 grains in Standard Mode, using pharmaceutical-grade strain-gauge scale components. That 0.04 figure works out to roughly one or two kernels of an extruded powder like H4350. Independent tests against lab-grade analytical scales have shown the unit often performs even tighter than its published spec with very little drift.
How fast does the MatchMaster dispense powder?
In Standard Mode most charges drop in under 20 seconds, and a single unit can keep pace with three ChargeMaster dispensers. A tuned MatchMaster will throw 38.5 grains of H4350 in under 7 seconds in Match Mode. Match Mode trickles more carefully for maximum precision, so it runs a bit slower than Standard, but you can fine-tune the dispense speeds to suit your powder.
Does the MatchMaster work with the RCBS app?
Yes. The MatchMaster connects over Bluetooth to the RCBS app, which includes pre-configured powder profiles, lets you fine-tune each tube's dispense behavior, and stores load details including photos of group sizes and velocities. The app can also manage up to 8 units at once if you run multiple dispensers on your bench.
How do you change powders in the MatchMaster?
The MatchMaster uses an improved quick-drain feature with a flexible tube that empties the 1lb hopper from the bottom. This lets you swap from one powder to another quickly and helps prevent cross-contamination between batches. The unit gives an audible alert when the drain is open so you don't accidentally leave it that way during a session.
