Unless somebody specifically says that the charge is weighed assume that it's measured by volume. By volume, is the only correct way of referencing black powder substitutes and it avoids confusion ... unless otherwise stated.

When I tested weighing BH209, ten charges measured by volume in a clear TC powder measure set at 105 grains, averaged 77.3 grains when weighed on an RCBS scale.

So ... using those results your weighed charge of 75 grains equals 101.9 grains by volume (in my clear TC powder measure).

Here's what Western Powder says about weighing charges of BH209 in their FAQ's.

5. Can I weigh my charges?

Yes. If you prefer to weigh charges, you can convert the volume load recommendations into weighed grains by multiplying the volume load by 0.7. Example: 100 units by volume x 0.7 = 70 grains by weight. 110 volume charge x 0.7 = 77 grains by weight.
