You are debating the RCBS ChargeMaster Link and need to know if the 0.1-grain accuracy actually holds up or if it is just marketing. This review checks the specs, app workflow, and owner reports to give you a straight answer on reliability.
In short: The ChargeMaster Link delivers true 0.1-grain precision on extruded powders when calibrated correctly. It adds Bluetooth data logging that simplifies load building but requires a stable mobile app connection for full features.

Combines RCBS reliability with Bluetooth data logging to eliminate manual transcription errors.
Lets you double-check every charge on a separate scale to catch static or bridging issues.
Small-capacity scales offer faster response and higher resolution for sub-0.1 grain adjustments.
Who it is for (and who should skip it)
The RCBS ChargeMaster Link is built for reloaders who load in batches of 20 to 50 rounds and want to track data without using paper logs. If you shoot competitive match rifles where every 0.5-grain variance matters, this unit is the correct tool. The other half of this decision is rcbs rebel press in canada.
It suits hand-loaders who work with extruded and spherical powders that flow consistently. The internal software manages the dispensing speed to match the powder characteristics.
Skip this device if you primarily load with fine flake powders. These types often cause static buildup or bridging in the hopper, which no amount of software can fully resolve.
It is also not the right fit if you lack a stable mobile connection. The Bluetooth features require a phone or tablet nearby, which adds a layer of complexity to a simple bench setup. If you prefer a fully standalone mechanical unit, look at older models without connectivity.
Pro tip: If you do not want to rely on Wi-Fi or Bluetooth, check if the unit supports standalone operation for basic dispensing.
The Bluetooth connection lets you save every charge to a digital log, replacing messy notebook entries.

What stands out about the accuracy specs
The scale uses a 2,000-grain capacity load cell with 0.1-grain resolution. This means the machine can distinguish between a 10.0 and 10.1-grain charge.
Owner experience reports show that on extruded powders, the device holds charges within a tight 0.1-grain band after proper calibration. It is not a zero-deviation tool; some variance is normal. If that sounds like your bench, read up on hornady lock and load powder dispenser reviews next.
The touchscreen interface displays the target charge and actual dispensed weight. You see the number before you commit the powder to the case, which prevents errors. The LCD is backlit, making it easy to read in low-light benches.
The drawbacks and setup hurdles
The mobile app is the main friction point. While the dispenser works standalone, accessing the full data logging and customization features requires a paired device. App updates can occasionally change the user interface.
Flake powders and light spherical loads often need manual pre-heating of the hopper to prevent static. Without this, the powder may stick to the walls and result in under-weights.
The unit is heavier than manual dispensers. It requires a solid, non-vibrating bench surface. Placing it on a soft mat or near a vibrating press can throw off the scale readings. The hopper size is standard, so you must refill it for large batches. You cannot just keep adding powder indefinitely.
Safety first: Always verify the powder charge with a second scale before seating the primer. Do not rely solely on the dispenser's internal display.
Setup and use tips for consistent results
Start by calibrating with the included weight. Place the scale on a hard surface away from air conditioning vents. Vibration and air drafts cause drift.
When switching powders, run the hopper empty first. Residual powder from a previous load can mix with the new type and alter the weight distribution.
Use the “slow” dispensing mode for the final 0.5 grains of any charge. This reduces the shock to the load cell and improves precision on small loads.
- Keep the hopper lid closed to prevent dust from entering the mechanism.
- Wipe the dispensing nozzle weekly to prevent clumping.
- Update the app to the latest version to ensure Bluetooth stability.
- Ensure your case is dry and clean before dispensing to avoid static attraction.
If you load in a cold environment, allow the unit to reach room temperature before starting. Electronic components can drift when cold, leading to inaccurate readings.
Alternatives worth a look
If you prefer a simpler unit without app integration, the RCBS ChargeMaster Supreme offers the same mechanical core with fewer digital features.
For those who want to verify every charge manually, the Frankford Arsenal DS-750 is a compact digital scale. It offers 0.1-grain accuracy on a 750-grain capacity, perfect for checking the dispenser’s output.
The DS-750 is battery-powered and lightweight, making it ideal for field verification or traveling to the range with your reloads. It fits easily in a pocket or small bag. Use it as a cross-check tool rather than a primary dispenser. We cover redding t7 stability and speed in a guide of its own.
Pro tip: Use the scale's tare function to zero it out with the empty case, so you only weigh the powder.
Acts as an independent check on your charges, catching any static or dispensing errors before you assemble the round.

The bottom line
The RCBS ChargeMaster Link is the top choice for reloaders who want data-driven precision and do not mind the app learning curve. It accurately dispenses extruded powders and saves significant time on batch loading. The next step is to buy a separate digital scale to independently verify your charges.

Frequently asked questions
Can the ChargeMaster Link dispense flake powders?
It can, but you will likely encounter static buildup. Most users find that pre-heating the hopper or using a static eliminator is necessary. Fine flake powders are not recommended for automated dispensing due to inconsistent flow.
How do I calibrate the RCBS ChargeMaster Link?
Use the included calibration weight. Place it on the platform, select the calibration mode in the settings, and let the machine adjust. Repeat this process whenever you move the unit or notice drift in your charge weights.
Is the ChargeMaster Link better than the Supreme?
The Link adds Bluetooth connectivity and advanced app features. The Supreme is simpler and more affordable. Choose the Link if you want digital logging; choose the Supreme if you want reliable dispensing without the extra tech.
Where to buy the RCBS ChargeMaster Link in Canada?
It is available through major online retailers like Amazon Canada and local gun shops carrying RCBS gear. Check your local firearms retailer for in-store demo units before buying online.
What is the best reloading book for accuracy?
Consider the “Reloading Handbook” by RCBS or “Conway’s Complete Reloading Handbook.” They cover the principles of consistency that complement a precision scale like the ChargeMaster Link.
