The bottle of blackpowder provides 87.5 shot of 80g volume.

The bottle of blackhorn provides 78 shots of 80g volume.


Another thing one may consider is each shot of 56 (weighed) grain Blackhorn will provide more energy to the bullet than each shot of 80 grain (weighed) black powder. One could actually use less Blackhorn, to get the same bullet energy.
