Drew, reading the above article leads me to the conclusion that some blame can be laid at the door of the powder manufacturers.
Knowing the entrenched mind set of the dram with no regard to the dram equivalent, it could therefore be argued that to make a powder of double the density of black, at that time, might be irresponsible.
These days we have ADI making Trail Boss powder in the shape of donuts to give bulk to the load & thereby make double charging (at least in a rifle case) near on impossible.
O.M
