Wow.
Finally saw one of those from a commercial maker.
I have print material that speaks of those cartridges, I have a really, really beautiful shotgun that was made for this kind of cartridge.
The neat thing about my shotgun is that it's a breechloading percussion gun that fires through the side of the cartridge near the base.
The gun is set up for a ramrod which would likely take care to clear any of the wire and paper that was left at the breech end after firing.
Also, my gun takes a slightly larger than 20b cartridge.
That 18b cartridge might be just right.
The whole load column was wrapped in paper, with the shot inside it's own paper cup.
The breech loaders fired a hot percussion cap through the side of the case.
My gun very much resembles a pinfire gun with it's big hammer shoes that reach a bit forward to hit the nipples.
How exciting!
