Also made in center fire I’ll post a photo of those later.
The one on the right should have a blue paper cup 7.46mm high with 0.74mm thick walls. A least mine came that way. My 16 bore, like yours did not come with a cup.
These are vertically-seamed brass bodies with paper covers, not drawn brass bodies. The CF shells are also made that way.
I’m not sure which way the cup should go but as the bullets are hollow based, but I think the cup should go mouth down to prevent the powder filling the bullet base. But like I said i don’t know for sure.
Other than that bit of whatever I have no further help.
Aaron, this type of cartridge and bullet was designed by Alfred Eugéne Courtier. After being loaded with the powder charge, a special gas check and then a thin fiber wad was placed before the bullet, and according to the manufacturer it could be reloaded up to 4 or 5 times.
