Seems like a good use for small primer cases.

I noticed that as well. Seems like a grease cookie underneath the slug would at least leave some lube for subsequent shots. Small primer cases bored out for a percussion cap carrier like the other video shows should work dandy. Although I don't know how the extractor groove would affect the placement of the pin. Makes me wish I had a chance to play some with the idea.
