I am using the above powder measurer, and so far have been weighing out every dispensed load. I have the screw adjuster set to dispense light, then I trickle in until the balance hits my required weight. At the weekend I needed 70+ rounds for a competition so I tried to reload on volume rather than weight but couldn't seem to get a consistent volume dispensed. I am loading 41 grains of H4350, I keep the hopper at a reasonably consistent level and have what I believe is a consistent 'throw' - i.e. a tap at the top and bottom of each throw to hopefully be consistent in the amount dropped into the drum. I am using the standard adjustment screw, not the micrometer adjuster.
