Have you tried reloading with any of the commercially manufactured black powder products for comparison (or are they even available to you)? I know how the manufacturers measure THEIR various granulations, but I do not know how YOU would, except with a magnifier and a "bigger than/less than" comparison. If your black powder had exactly the same formulation as the commercial stuff, and your granulation was larger, it would lead me to expect lower velocities from it, for it will tend to be slower-burning, and less of it may be put in the case...
