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.

Claims

1. An improved firearm projectile comprising:

a) a cylindrical central section having an outer surface;

b) a trailing section in axial alignment with the central section and being integrally formed with the central section and projecting rearwardly therefrom; and

c) a leading section in axial alignment with the central section comprising an axially aligned ogive base segment and a conic segment, the conic segment being integral with the ogive base segment of the leading section and extending forwardly therefrom, the base segment of the leading section being integral with the central section and extending forwardly therefrom, the conic section having a conical surface defined by an apex angle relative to the axis of the leading section being in the range of 20°

-40°

of arc.

3. An improved firearm projectile as defined claim 1 wherein the axial length of the conic segment is approximately 15-20% of the total axial length of the leading section.

2. (canceled)

4. (canceled)

5. An improved firearm projectile comprising:

a) a cylindrical central section having an outer surface;

b) a trailing section in axial alignment with the central section and being integrally formed with the central section and projecting rearwardly therefrom; and

c) a leading section in axial alignment with the central section comprising an axially aligned secant ogive base segment and a conic segment, the conic segment being integral with the secant ogive base segment and extending forwardly therefrom, the conic segment having a conical surface defined by an apex angle in the range of 20°

-40°

of arc relative to the axis of the leading section, the axial length of the conic segment being in the range of 15-20% of the total axial length of the leading section.

6. A method for manufacturing an improved firearm projectile comprising:

a) providing a die block having an upper cylindrical bore and a lower cylindrical bore in axial communication with one another;

b) providing a deformable projectile core having a cylindrical central section integral with a curved leading section extending forwardly from the central section;

c) providing a projectile seating element having an upper axial seating bore adapted to be slidably engaged within the lower cylindrical bore of the die block;

d) positioning the deformable projectile core within the seating bore of the projectile seating element;

e) providing a die piece adapted to be slidably engaged within the upper cylindrical bore of the die block, the die piece having an axially aligned conical receiving surface disposed in the lower end thereof;

f) positioning the die piece within the upper cylindrical bore until the conical receiving surface of the die piece is in engagement with the curved leading section of the deformable projectile core; and

g) deforming the curved leading section of the projectile core until the upper portion of the leading section of the projectile core into a conic section defining the conical receiving surface of the die piece.

7. An improved firearm projectile manufactured by the method of claim 6.
