I'm kinda new to this, but based on WoodWise's comment above, I think some are confused on the volume measurement. The volume measurement represents a weight equivalent of black powder. The various black powder substitutes are designed to give similar performance to black powder if the same volume is used and since these substitutes are less dense than black powder, equivalent volumes will weight less. If you measure the volume equivalent of 100 gr. using T7 in your brass and then weightit, it will weight less than 100 gr. If you weigh out 150 gr. of T7, for example, and use this charge rather than the volume equivalent of 150 gr, you will likely be exceeding the maximum recommended charge.

So there wouldn't be anything wrong with weighing the charges, but you would have to compensate for the lower density (weight/volume)of the powder your using.

I just wanted to write this out for my own understanding, so feel free to correct me or state it more clearly.
