RE: weighing blackpowder charge ?
I have to " weigh in" with eldequello' s method. I' ve tried weighing charges and found them less accurate than using my volume measure.
A consistent method like eldequello' s is the sure fire way to consistent accuracy.
BTW...........I only tap my neasure twice when using 777 because it is cut finer & compresses more easily than black or Pyro.
