Note though that whether a 42 grain, 36 grain, 33 grain or other all those powders listed as "Bulk" were intended to load a 3 dram equivalent load with a 3 dram Black Powder Dipper. When things went out the window though was when folks loaded Infallible, Ballistite or other dense powders with a bulk dipper.
A 3 dram dipper full of Infallible was not the equivalent of a 3 dram dipper full of either Schultz or New Shultz. The 3 dram dipper full of Schultz would weigh 42 grains while the same dipper full of New Shultz would only weigh 36 grains, but they were both 3 dram equivalent.
A 1913 LAC catalog list 24 grains of Infallible as a 3 dram equivalent load. Heaviest load listed ion 12 ga was 28 grains for a 3˝ dram Equiv. A 3 dram bulk dipper full of Infallible would have weighed about 48 grains. (This derived from the settings from an old Lyman Handbook for setting the #5 powder measure) Note also that Black Powder burns at virtually the same speed regardless of conditions, not so with Smokeless. Double charging with Black is not near as Catastrophic as Double Charging Smokeless.
