Why is it that Hodgdon has load data, charge in grains weight, on smokeless powder labels but does not even mention the fact on BP subs they offer, that BP charges are given in a volume not weight or any conversion data?
I understand there are charts out there and if one has "real" BP they can make their own measure at that point but it seems a simple, "charge weight of pyrodex X 1.28 = BP charge weight/assumed volume grain charge" or something similar, would be nice.
Seems better than weighing out a 70 grain charge of say Pyrodex and thinking your exact when the BP volume equivalent is 90 grains.
