Abstract: A packing case (1) for a large-caliber cartridge (2), having a thin-walled cartridge case (3) and a projectile (4), which protrudes at least partially out of the front of the cartridge casing (3), and has at its outer circumference an annular stop groove (5), with the packing case (1) including an outer case (6) and an inner case (7) that comprises at least two partial cases disposed one behind the other. To enable the cartridge to be easily secured in the packing case and subsequently removed, at least two spring-loaded stop elements (19) that can pivot toward the projectile (4) and have guide elements (21) are provided. The stop elements extend with a form-fit into the stop groove (5) of the projectile (4) and are supported at the rear against a partial case (11) of the inner case (7).
