The present invention relates to an innovative hollow bullet design, which fundamentally diverges from conventional solid bullet configurations. This design encompasses a brass casing, gun powder, a plastic wad, and a distinctively structured nozzled projectile. The nozzled projectile features a hollow portion that starts wider at the proximal end and narrows towards the distal end, ingeniously manipulating airflow to enhance kinetic energy during flight. This unique aerodynamic efficiency potentially increases impact force and stability over extended distances. The bullet maintains standard size and weight, ensuring compatibility with existing firearms, and offers significant improvements in performance for both civilian and military applications.
