Firearms projectile having jacket runner
First Claim
1. A small munitions projectile for a firearm having a barrel with a primary bore of a certain diameter, the projectile comprising:
- a bullet having a longitudinal axis and a maximum diameter, the bullet comprising a tapered front section, a cylindrical middle section having a certain diameter and an axial length, and an end section, the middle section having opposed top and bottom portions and a cylindrical recessed receiving portion intermediate the top and bottom portions, the recessed receiving portion having a diameter less than the middle section diameter, and an elongated ring-shaped jacket runner formed from a resilient, shape-retaining material, the jacket runner securely positioned co-axially around the bullet adjacent the recessed receiving portion, the jacket runner having an inner diameter slightly less than or equal to the recessed receiving portion diameter, and an outer diameter greater than the diameter of the middle section, and wherein the maximum diameter of the bullet is less than the primary bore diameter of the firearm, and the outer diameter of the jacket runner is greater than the primary bore diameter of the firearm.

Abstract
A projectile for small munitions is provided having a bullet with an integral jacket runner formed from a resilient, shape-retaining material. The projectile comprises a bullet having a tapered front section, a cylindrical middle section and a tapered end section. The middle section includes a recessed retaining portion over which the resilient jacket runner is securely positioned or formed. The maximum diameter of the bullet is less than the primary bore diameter of the firearm barrel, and the outer diameter of the jacket runner when positioned around the bullet, is slightly greater than the primary bore diameter, whereby rifling in the barrel scores the jacket runner and not the bullet, and imparts spin to the jacket runner during firing and hence to the bullet which is integral therewith, achieving enhanced gas checking efficiency, accuracy and velocity. The integral jacket runner remains on the bullet after firing and downrange to its ultimate destination. High speed production of this projectile can be achieved due to the resiliency or elastic memory of the jacket runner.

16. A process for making a small munitions projectile including a bullet having a longitudinal axis, a front section, a middle section having an axial length and including a top portion and a bottom portion, and an end section, the bullet including a maximum diameter, and a jacket runner positioned therearound intermediate the top portion and the bottom portion, said process comprising:
-
forming a bullet having a cylindrical recessed receiving portion intermediate the top portion and bottom portion of the middle section, the recessed receiving portion having a diameter less than the maximum diameter of the bullet;
forming an elongated ring-shaped jacket runner from a resilient, shape-retaining material, the jacket having an outer diameter, and an inner diameter less than or equal to the diameter of the recessed receiving portion;
stretching the jacket runner for passing over the maximum diameter of the bullet;
positioning the jacket runner over the recessed receiving portion;
allowing the jacket runner to return essentially to its original size and shape, wherein the outer diameter of the jacket runner is greater than the maximum diameter of the bullet; and
securing the jacket runner onto the recessed receiving portion, wherein the jacket runner is adapted to remain integral with the bullet even subsequent to firing it from a firearm. - View Dependent Claims (17, 18, 19, 20)

21. A process for making a small munitions projectile including a bullet having a longitudinal axis, a front section, a middle section including a top portion and a bottom portion, and an end section, the bullet including a maximum diameter, and a jacket runner positioned therearound, said process comprising:
-
forming a bullet having a cylindrical recessed receiving portion intermediate the top portion and bottom portion of the middle section, the recessed receiving portion having a diameter less than the maximum diameter of the bullet;
forming an elongated ring-shaped jacket runner around the recessed receiving portion, the jacket runner formed from a resilient, shape-retaining synthetic material, and having an outer diameter, and an inner diameter less than or equal to the diameter of the recessed receiving portion; and
securing the jacket runner onto the recessed receiving portion, wherein the jacket runner is adapted to remain integral with the bullet even subsequent to firing it from a firearm. - View Dependent Claims (22, 23, 24, 25)
