I got a pretty good powder measure, some kind of RCBS .Using stick type powder I never trust it. Nothing to do with the powder measure but rather the way the kernals fall into the powder hopper. You can fill the hopper and then bump it a couple time and make the weight change. Not for me, I weight every load with stick powder. Ball powder measure's much better and once I get the thing set I throw 10 loads and weight them. They need to come out real close to ten time's one charge or I don't just throw them. Flake powder is in it's own world. Only reason to weight it is to set the measure! I don't weight handgun loads other than to set the powder measure.
