As for one measuring different than the other. Probably - but this is due to grain size. For example, 80 grains of FFFg by volume will weigh more than 80 gr of FFg by volume simply because the grains are finer and there will be less air space.
Hope this helps
This is what I was wondering about. I know the flakes or pellets are different sizes so I was wondering, for example, how 90 grains of Pyrodex would be compared to 90 grains of BH209. Like Schultz would say, "I know nothing!"
