Patent ID: 7484459

Claim:
An ammunition projectile ( 10 , 20 ), for a firearm, having diminished penetration into a soft medium, said projectile ( 10 , 20 ) comprising a nose ( 11 , 21 ) and a cap ( 12 , 22 ), said nose ( 11 , 21 ) forming a leading end of the projectile and being essentially conical in shape and comprising at least two indentations ( 14 , 24 ), each respective indentation being disposed in an external surface of the nose and essentially symmetrically in relation to a respective longitudinal axial plane coincident with a central longitudinal axis of said projectile and bisecting the respective indentation, each indentation having a curved profile from a first edge to a second edge symmetrical with respect to one of the respective central longitudinal axis of the projectiie and the respective longitudinal axial plane, a trailing portion and a leading portion of each of the at least two indentations ( 14 , 24 ) is curved and a portion of each opposed sidewall of each of the at least two indentations is straight and connects the leading portion and the trailing portion and the portion of each opposed sidewall tapers away from one another upon extending from the leading portion to the trailing portion of the indentation so that said projectile, during trajectory of the projectile through air, is sufficiently slowed so as to diminish penetration of said projectile into a soft medium without significantly altering a trajectory precision of said projectile.
