The problem I've had with flake or the small fine powders and some of the electronic digital scales or electronic dispensers like the Chargemaster is that powder is so light many of those scales can't measure the tiny changes as it's trickling the last little bit in and will go along adding adding adding registering no change on the scale then all of a sudden register it but then it's to late and you're over your target weight and typically that type of powder is used in small cases where a 1/10th or two over is a pretty significant difference. I had this problem trying to use my Chargemasters for loading 17 Hornet ammo. I have a A&D FX120 scale that is quite a bit higher quality then any of my other dig. electronic scales or dispensers and it will consistently pick up even the very slightest change in weight with that tiny flake or ball powder. Unfortunately, they cost quite a bit more but they are a much higher quality scale.
