Interesting they used 30gr. per dram, while a dram is actually 27.3gr.

Daryl:
The reason for using 30 grains per dram is that 'modern' black powder (especially Goex!) is around 10 percent less 'powerful' than the original stuff more than a century ago. That's progress!

Using 30 grains per dram will achieve 'proper' regulating velocities in most black-powder doubles. This was explained elsewhere in Frank's article I believe.
