Abstract
The present invention relates to a bullet including an air-guiding recess, comprising: a head 20; and a tail 30 disposed behind the head 20, and including an odd number of air-guiding recesses 32 formed so as to be curved in the bottom and outer circumferential surfaces thereof. The air-guiding recess 32 is characterized by having a sloped bottom that increases in depth while progressing to the bottom surface of the tail 30. 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.
