Volumetric Units are NOT the same as weight in grains. Blackhorn is used by volume and therefore the charge is a measurement by volume. A volume charge is measured with a standard black powder measure. It is not weighed and a setting of 100 does not mean that you have 100 grains by weight, not even black powder.
