Hoot4570,
The bullet seater seems to be for 9.3x70R, rather than 9.3x72R, I wonder if the other devices are to limit bullet seating depth to adapt the seater for 72 mm cases. I noted the ammo box end indicates the cartridges were the "D" version with 15gram J ( hunting ?) bullet. If the two devices are closed at the end, maybe they are powder measures.
