Bullet with increased effective range

机译:有效范围增加的子弹

摘要

The present invention relates to a bullet with an increased effective range. The bullet includes a front end portion (10) having a hemispherical shape, a recess portion (20) connected to a rear end of the front end portion (10) and having a curved surface that is recessed inward, an inclined portion (30) connected to a rear end of the recess portion (20) and inclined at a predetermined angle (A) with respect to a horizontal line, a stepped portion (40) connected to a rear end of the inclined portion (30) and inclined at a predetermined angle (A′) with respect to the horizontal line, and fluid inducing grooves formed from the rear to a rear end surface of the bullet (1). Thus, when the bullet passes through underwater, super cavitation may be more effectively generated and maintained for even longer to significantly increase the effective range of the bullet.
