Thermoset Polymer Guide Band for Projectiles
First Claim
1. A projectile, comprising:
- a leading end formed by a tip having an ogive configuration;
a trailing end formed by a frusto-conical base;
a cylindrical mid-section interconnecting said tip and said frusto-conical base to one another;
said cylindrical mid-section having a diameter less than a diameter of said tip at a trailing end of said tip and less than a diameter of said frusto-conical base at a leading end of said frusto-conical base;
a first annular shoulder formed where a trailing end of said tip meets a leading end of said cylindrical mid-section;
a second annular shoulder formed where a trailing end of said cylindrical mid-section meets a leading end of said frusto-conical base;
a metallic band having a trailing end disposed in abutting relation to said second annular shoulder;
a third annular shoulder formed where a leading end of said metallic band meets said cylindrical mid-section; and
a thermoset polymer guide band having a trailing end disposed in abutting relation to said third annular shoulder and a leading end disposed in abutting relation to said first annular shoulder said thermoset polymer guide band comforming to the shape and size of said cylindrical mid-section.

Abstract
A projectile includes a leading end formed by a tip having an ogive configuration, a trailing end formed by a frusto-conical base, and a cylindrical mid-section interconnecting the tip and the base. A first annular shoulder is formed where the tip meets the cylindrical mid-section and a second annular shoulder is formed where the mid-section meets the base. A metallic band abuts the second annular shoulder and a third annular shoulder is formed where the metallic band meets the cylindrical mid-section. A trailing end of a thermoset polymer guide band abuts the third annular shoulder and a leading end abuts the first annular shoulder. The thermoset polymer guide band conforms to the shape and size of the cylindrical mid-section. The thermoset polymer guide band may be impregnated with barrel treatment chemicals so that the barrel is cleaned and lubricated when the projectile is fired.
