Benefits of technology

This patent is about a new projectile design for firearms that improves its aerodynamic efficiency. The projectile has a cylindrical central section that comes into full contact with the firearm's barrel rifling and a leading section that is conical in shape. The conical section has a reduced area, which reduces aerodynamic drag and improves the projectile's stability. The new design is inexpensive and easy to make. Overall, this new projectile design enhances external ballistics, improves aerodynamic stability, and reduces the area of the projectile's meplat, resulting in a more efficient and accurate firearm.

Problems solved by technology

This configuration can adversely affects the aerodynamic efficiency of the projectile.

Embodiment Construction

.

[0021]The present invention design for the improvement of a projectile for a firearm can be best understood by initial reference to FIGS. 2a and 2b which illustrate prior art projectile designs employing a tangent ogive design and a secant ogive design, respectively. The design of a bullet or projectile for firearms must solve two basic problems. Firstly, while the projectile is in the barrel of a firearm, it must form a seal with the firearm's bore. The projectile must also engage the barrel rifling without damaging or excessively fouling the firearms bore, and, without distorting the projectile which could reduce accuracy. The interactions between the projectile and the bore of the firearm is generally referred to as “internal ballistics.” The present invention relates to the principles affecting the projectile once it leaves the barrel of the firearm, this being generally referred to as “external ballistics.” The geometry of a bullet or projectile can be broken down into symmetr...

Abstract

A solid projectile for a firearm having a central cylindrical section defining a bearing surface and an integral, coaxial leading section tapered into a uniform conical surface, the apex at the distal end thereof projecting to a point or apex. The apex angle of the conical surface of the leading section of the projectile is within the range of 20°-40° of arc.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention generally relates to projectiles intended to be fired from firearms, and more particularly to a projectile that includes a specially contoured leading section that is designed to enhance the aerodynamic properties of the projectile and the method of manufacturing the projectile.2. Description of the Prior Art[0002]The prior art discloses many attempts to improve the basic design of projectiles intended for use with firearms. With the interest that exists in the field of sport target shooting and with the interest of outdoorsmen, hunters and the like, substantial attention has been given to enhance the external ballistics of the projectile through the design of bullets that yield greater accuracy and range. In addition to accuracy and range, concern has been paid to increasing the velocity of a projectile or a bullet for a given charge. Increasing the velocity of the projectile as well as reducing the dra...
