Abstract
The present invention relates to a bullet including an air-guiding recess, comprising: a head; and a taildisposed behind the head, and including an odd number of air-guiding recessesformed so as to be curved in the bottom and outer circumferential surfaces thereof. The air-guiding recessis characterized by having a sloped bottom that increases in depth while progressing to the bottom surface of the tail. Accordingly, vortex is prevented from being generated at the rear side of the bullet, so as to significantly increase the effective range thereof and simultaneously improve accuracy when shooting same.
