Looking for some expertise in measuring black powder? I was wondering, if you measure powder with a tube that has the grain markings on it, do you tap the tube and let the powder settle and then read the powder measurement? Or would the actual powder size be the measurement when the powder is initially poured and unsettled? I understand that as long as I'm consistent it probably won't matter, but I would like to know how many grains I am actually shooting. Would like to know if anybody has ever compared these two methods for measuring powder? Any insight would be appreciated. Thanks.
