The problem early-on when smokeless first came into use was that folks were loading their shells with smokeless powder to black powder specs or recipes. In those days black powder was measured in drams and to use smokeless powder it must be measured in a 'dram equivalent' which was/is a measurement determined by the combustion and resultant pressures generated by each. If smokeless powder was measured simply in drams you would have pressures far too great for the durability of the guns of the day.
