Abstract
Projectile device that being applicable to those used in compressed air shotguns of the so-called "diabolo" type, is essentially characterized in that a double circular perimeter guide is made at the head of the projectile, delimiting a housing between them, which provides better retention of the air of impulsion, improving also the conditions of aim.
