A projectile, consisting of a ductile material, wherein the projectile has a structure dimensioned and shaped in such a way that, after being fired into a gelatinous mass the projectile hits into and is caught, being stuck in it is deformed in such a way that at least two prongs radially bent outwards and bent back in the projectile longitudinal direction from a cylindrical, solid base end section are formed, wherein two other identically or similarly shaped teeth protruding from the base end section are formed between the at least two bent-back prongs, wherein the radial extension of the at least two teeth is less than that of the at least two prongs, wherein the base end section has a deformation-side central recess, from which the at least two prongs and the at least two teeth are radially bent outwards.
