Yes, and I think the cartridge case was formed after it was primed and the compressed charge of BP was put into the case. Seems a dangerous loading practice.
Conventional thinking is that there should be no airspace in black powder cartridges, but I’ve found no detrimental effects with a moderate amount of air space. I load the .577-450 Martini Henry with 85 gr Fg and seat the 500 gr bullet so it is close to the rifling which leaves a lot of air space. IIRC, the solid drawn case holds about 120 gr Fg which is a stout load with a 500 gr bullet.
