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.

This composition achieves above 90% biodegradation in soil in much less than two years, together with high impact resistance, lower moisture absorption (with the associated advantages of greater dimensional stability, lower production costs and better and safer ballistics), compatibility with existing injection and production processes, and lower production costs owing to its greater fluidity.

An anti-equipment cartridge is provided, comprising: a shotshell cartridge adapted to be fired from a firearm; and powder included in the cartridge configured to fire pellets at a velocity sufficient to generate force upon impact to destroy or compromise a target.
