Projectile, in particular deformation and/or partial fragmentation projectile, and method for producing a projectile

The invention relates to a projectile, in particular a deformation and/or partial fragmentation projectile, comprising a substantially cylindrical projectile tail; a nose-side projectile head which adjoins the projectile tail and comprises a substantially central opening that opens into a cavity extending axially from the projectile head in the direction of the projectile tail, preferably into the projectile tail, said cavity having a cavity base and being delimited by a wall; and a tear-off groove which is introduced into the wall and at least partly encircles the cavity and which is arranged at a distance of at least 10% of the longitudinal extension of the cavity from the cavity base and has a radial depth of at least 10% of the caliber diameter and/or at least 30% of the radial wall thickness of the wall surrounding the cavity.
