RCBSChargeMaster Link Powder Dispenser, Bluetooth Compatible Gun Powder Dispenser with 0.1 Grain Accuracy and 2000-Grain Capacity Touchscreen Display

Works as advertised. The quick and easy way to produce powder drops. Unit is easy to use and drops the exact amount requested time after tim.

I was conflicted about buying this. Some YouTube video reviews claim it is way less accurate (+/- .2 grains or worse) and much slower than others. Not my experience at all.I ran tests of ten charges of 24.0 and 48.0 Varget which is a small kernel “stick” powder that can be a problem in mechanical measures. Then ten charges of 25.5 gn H335 which is a fine grain ball powder. In all cases most charges were +/- .05 gr as verified on my balance beam RCBS 10-10 scale (basically between the .1 gn markings on the scale). A couple would be dead on and usuall one at both extremes +/- .1 gr.This is following the manual instructions to let it warm up 20 minutes when first powered on. Then to calibrate it, and recalibrate every time it is turned of and back on for less than 20 minutes, for instance when I emptied the hopper or moved its position. This is a simple two minute process. The scale has a bubble level and adjustable feet.Very easy to use. For manual dispensing just make sure it is zeroed with the pan on it, then use the touch screen numeric pad to enter your charge weight, and press the green Go button. It will rapidly trickle up to about half a grain of the charge weight then slow way down to trickle a couple of kernels of Varget or several ball grains of H335 at a time to edge up to the charge weight. It took 17 seconds for the 25.5 and 21 seconds for a 50.0 charge weight.This is at least as good but I think slightly better than my trusty RCBS Uniflow mechanical measure. And considering on the mechanical I would recycle charges that hung up on the sticks (every five or six throws) it is about as fast and much less frustrating.Stick powders have been the best for me for precision match loads but the most troublesome to get accurate charge weights. Either tedious manual trickling or frequent hang ups and recycles with the mechanical measure.The Bluetooth link and app were super easy to set up. Connected easily and stayed connected. You can run the calibration and charging from the app or keypad. They both keep track of number of charges thrown so you can compare at the end if you missed any cases or double charged any.This ChargeMaster Link is fantastic. There may be other good brands as well. But this entry level auto dispenser from RCBS is a dream. If you have problems you either got a lemon so contact RCBS. Or you need to let it warm up or turn on and off and calibrate when moving it. Or you have issues with static or electronic interference. I did use Blaster Graphite Dry Lubricant spray on a cotton swab to lube the trickler tube first. It unscrews from the scale.

a huge timesaver! how did i live so long without one of these auto-tricklers? the RCBS ChargeMaster Link is a great value. ii’s very repeatable and appears to be accurate - it matches my calibration weights perfectly in the range of 2-50 grains. easy to use, easy to calibrate. i like the features of blue tooth and being able to select auto vs manual mode. haven’t needed grams capability, just use it in grains for powder. emptying out powder at the end of a session is fast & easy. it’s plastic so i’m not sure about long-term durability, thus the 4 stars. but with care i expect to last years. it has the ability to display to 2 decimal points (it does this in calibration mode). i wish it would display actual charge weights to same 2 decimal points but only shows 1. nothing in documentation on how to change it. have used it for a few hundred loads already and very satisfied with it so far!RCBS customer service via email was pretty good. sent them a question on the need for the “wind cover” and got a response in a couple days. will be asking them about display update for 2 decimals next.

Saves a lot of time in reloading. Weighs the power out fast and accurate.

This powder measures to the exact grain. Very few times over

It was delivered quickly and packaged securely with much plastic wrap. It’s accurate and not heavy. Great instruction easy to understand.

This works good but as with all scales under $500 it drifts and simple needs to be recalibrated.... It's a real time saver with powders that can't be thrown out of a powder dispenser.... It normally drops the charge on the money but accuracy is only within a tenth of a grain like most scales.... I double check each charge with a separate digital scale and it's rarely off , the system works good and really speeds things up compared to the trickle up method... I highly suggest wiping it down before each use with a dryer sheet to remove static electricity.... Static electricity is what causes most problems with any digital scale... Even leaving the dryer sheet in the powder hopper when storing the unit... Keeping static electricity off the unit will stop misreads and drifting on any digital scale or at least keep them to a minimum.... I don't use the blue tooth function... System works good and saves a lot of time with tough powders... Can only imagine how good it would be with an easy to use powder...

This is the coolest thing I have bought for reloading in a long time. It is super accurate dispensing powder. The first time I used it, I would check each charge on an independent scale and it was always within .1 grains. I need accuracy for what I am doing, and am SO happy with this!
