DRAM REFERENCE for FFg (2F) per 1975 Lyman Black Powder Handbook
One Dram = 27.34 grains of 2F black powder
2 dram (volume) of 2F = 54.68 grains/11 grains per dram equivalent for Smokeless Diamond = almost 5 Dram Eq.
BUT the early Bulk Smokeless 42 gr. / 3 dram ("E.C." and "Schultze" = 14 grains/dram)
COULD be loaded volumetrically equivalent to 82 grain / 3 Dram black powderSO Smokeless Diamond 11 grains/dram
if loaded volumetrically COULD be about 1.27 X the 14 grains/dram Bulk powders by volume.
So 2 dram volumetrically might be about 28 grains Smokeless Diamond or about 2 1/2 Dr. Eq.
And I'm only guessing and have no clue
