What I meant was the volume of 40 grains of 3F seemed to weigh in closer to the digital scale 40 grains of weight. 3F Taped down settled and topped off was heavier on the digital scale.
I for one will be using the digital scale from now on for smack on consistency.
Probably not a big deal with BP, but fun for a perfectionist like me
I have run volume / weight tests on different powders and granulation sizes using the Lyman 55 and B&M measures.
Interestingly, they have been regulated with an earlier black powder that has the same density as Swiss.
In other words, when the Lyman measure is set at "40" and the B&M is set for 40 grs. they dispense:
...Swiss 1 1/2 - 40.0 grs
.......Swiss 2F - 40.0 grs
.......Swiss 3F - 39.5 grs.
Schuetzen 2F - 37.0 grs
Schuetzen 3F - 37.2 grs
.........KIK 2F - 36.0 grs
.......Goex 2F - 36.0 grs
.......Goex 3F - 35.8 grs.
.........KIK 3F - 35.4 grs
Of course different lots of powder can vary a bit from one to the other.
Those values are from the ones I have on hand.
