    Wind currents can mess with your readings. Go to your local Dollar Store and pick up a clear storage tub and place it over your scale while measuring your charges.

    I have a Lyman scale and dispenser also I set mine 1.0 grain light and use a trickier on a different scale every single charge . And zero the trickler scale every 3-4 charges. Yeah it may take an extra little bit but my powder weights are spot on every case. I’ve checked them multiple times on a beam scale and so far it’s the most accurate way I’ve found. Generally the dispenser scale will throw about a tenth heavy just because it is try to get shut down and an extra grain or so falls out . But trickling up to my desired charge is very consistent.

    They say cry once but I didn't want to cry that hard when I looked at the A&D. I went to a Gem pro 250 seems to be really good. I’m sure one day I’ll do the 120 as they look like a really nice scale set up but I’ll also have to buy wife diamonds when I do so I have to save for a while.

    A bit of a basic question but are you calibrating the scale with a check weight every time you turn it on? Any time the scale is turned on, bumped or moved it needs to be recalibrated. I also have weighed my pan and make sure it reads the correct weight when it's placed on the scale, before I zero it. It will also read the same weight (as a minus) when the pan is removed.

    Just one more thing to check!

    I have a RCBS Rangemaster E-2000 that I have been using for over 5 years for several thousand rounds without any problems whatsoever. There is no doubt digital scales are different to use and you cannot use same techniques from beam scale to powder scale to get same result. They just operate differently. First lesson I learned is digital scales are not balance beams relative to instant weigh changes so you cannot expect to see the same response BUT you can get fast results if you develop your own methodology to see the trickle powder changes. Some may think tedious but once I started to get accustom to how I was using it, the process became easier and faster.

    Calibration was easy and fast for the unit I have and would hold calibration through 50 rounds without any problem at all. I was initially checking every 10 rounds with balance beam and was dead on every single time just to be sure. I also would weigh calibration weights close to the powder weight I was using and they were also dead on every single time. One way to monitor the calibration was to observe the minus tare weight of the pan that shows when you remove the pan. If it returned same minus number, you are essentially still calibrated to the zero of the pan. I never really saw any calibration changes using this scale. Maybe just lucky or the room I load in.

    Here's the rub to get accurate final powder weights that I came up with that works for me. Once I trickled in powder to be around couple tenths below the desired weight, I would tilt the pan to allow the scale to cycle back to the minus tare weight of the pan which is instantaneous and return pan to scale. This assures you have the correct final weight on the scale so you can trickle in the remaining tenths for final weight. After each trickle, remove pan as above and return to scale which will immediately record the slightest powder change. If you don't remove scale, it takes forever to see a change and in fact you will likely blow by your final desired weight. Once you get knack for the added slight trickle powder change, the process speeds up immensely. You actually develop a sense for how much you need to add to get to final weight so the time gets shorter each time you use the scale.

    Yes they are sensitive to temperature, light (incandescent or fluorescent) and drafts. I am lucky since I have a room in basement that cuts everything off so it isn't bothered by any extraneous interference.

    I wanted to really get the most accurate weight possible (remember the scale takes the closes weight to the tenth) and test thru my chronograph. I weighed the charge to 0.1 below the desired weight and used a tweezer to drop one extruded granule at a time into the pan, raising the pan and resetting after each added granule. I could actually see the change from the 0.1 weight below the desired weight change to the weight by one granule added. OK, how many are laughing? I went to range and the results were interesting to say the least. The average velocity was consistent and the ES was generally 10 or less and the SD was 5 or less. This test was done with RL-16 load for .270. Tedious is understatement but is how I weigh loads now with extruded powder. I actually started to laugh at this when I was loading my .243 and it was ball powder. Yep, passed on trying it there.

    Best suggestion I can make is to develop a process to weigh on the digital scale that gives you the fastest and most accurate response to powder being added to the pan. I would bet it is far different from how you used your balance beam scale.

    This is pretty much how I reload all the time. I want my charges as close to each other as possible. I'm never looking for a faster way to reload, only more accurate. It probably is overkill but I seem to get good results doing it this way.
