Wouldn't modifying dippers lead to measurement errors?They are graduated for volume so they are powder specific altering the volume could cause the weight to change unpredictably and render them practically useless.
Come again? A dipper is a dipper. If you modify it, it is still a dipper, just a different volume dipper. Why would the charge weight change unpredictably if you use a dipper that has been trimmed down a few thousandths vs the same dipper in stock form?
There is a disconnect somewhere, I am not sure what you are trying to say.
