I have had a Chargemnaster LITE for about 3 years or so. VERY reliable and very accurate. The other day, I was loading multiply-sized loads to do a ladder test for my Cowoby Action Shooting, and because of the low power loads used, and the fact that I am using the same cartridges in both the rifle and the revolvers, the loading required loading 3.2g, 3.4g, 3.6g, 3.8g, 4.0g, and 4.2g. I am loading on a Dillon XL750, and I needed to change the amount of powder every 20 rounds.I was amazed at how well that Lite supported this task.
It was SO consistent that when I was trying to set the Dillon powder dispenser to 3.2g, I needed only a very few changes to the adjustment screw on the Dillon to dial it in and get CONSISTENT weights on the Lite. In fact, once I had the 3.2g dialed in, I dropped in one charge from the Dillon after another, without removing the previous charges, reasoning that sooner or later the accumulating total would "miss a beat" and be "off' by a tenth or more. But that did not happen. The total on the scale read EXACTLY 3.2g, then 6.4g, then 9.6g, etc. until i finished at exactly 32.0g.
During the process of setting up each individual weight after that, the consistency of the Lite made it easy to see after just a few charges at each trial weight, exactly what direction I need to go (more weight or less), and how MUCH more or less, because I could see what I call "the incremental creep" after just a few drops at the current trial weight.
What I mean is that when trying for 3.4g, when I got to the point where the Lite displayed 3.4g, I kept adding subsequent drops from the Dillon to the pan by removing the pan from the platen, adding the powder just dropped, replacing the pan on the platen, and reading the new cumulative total weight. If after 4 "3.4g" charges were in the pan, the pan displayed "13.5g instead of the expected "13.6g", I knew that I was very close to a true 3.4g, but just a little low. In fact, probably (13.6-13.5)/4 = 0.025g low. (I say "probably" because you cannot truly expect that 13.5g to be EXACTLY 13.5, as the 0.1 scale resolution means it could be merely closer to 13.5 than to 13.6., and that's just the display resolution. There is obviously also some actual "scale" error since this is not a costly "laboratory" scale.
So I would make a very slight adjustment to the Dillon adjustment screw, and try again to do 4 or 5 drops. Once I got to the point where the sequential reads were 3.4, then 6.8, then 10.2, then 13.6, I KNEW I was VERY close to the perfect 3.4g I wanted.
Using this technique allowed me to attain better final accuracy than merely stopping the first time the scale "rounded" to display "3.4g".
I am impressed by the Chargemaster Lite. The Link, with its Bluetooth capability probably offers some extra features. Like maybe the ability to accumulate the actual readings on your bLuetooth equipped laptop so that you have an exact record of every charge you loaded. If you then assemble your cartridges and load your ammo box in the same order was you drop the charges, you have a solid record of what you are actually shooting for each individual round.
