| 20110259232 | Thermoset Polymer Guide Band for Projectiles - 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. | 10-27-2011 |
| 20110259231 | Drag Effect Trajectory Enhanced Projectile - A projectile includes a cartridge and a hollow bullet. A propellant fills the cartridge and the hollow bullet to increase the velocity of the bullet when fired. The hollow bullet has a flattened leading end and an annular ring is secured to the flattened leading end in the center of the flat region. The flattened leading end and the annular ring move a center of pressure forwardly so that a center of pressure is forward of a center of gravity of the bullet when the bullet is in flight. In a second embodiment, a plurality of circumferentially spaced apart slits is formed in a trailing end of the hollow bullet, creating a plurality of circumferentially spaced apart fins that flare radially outwardly upon impact with a soft target. | 10-27-2011 |
| 20110155016 | Synchronized Spin Multi-Component Projectile - A projectile includes a leading part formed by a tip and a tip base that form a first annular shoulder where they meet. A trailing part of the projectile is formed by a base having a frusto-conical trailing end and a cylindrical leading end of truncate extent that forms a tail drive. A second annular shoulder is formed where a cylindrical rod meets the tail drive. A flat trailing end of the tip base and a flat leading end of the cylindrical rod abut one another when the projectile is assembled. A cylindrical interface has a leading extent abutting the first annular shoulder and a trailing end abutting the second annular shoulder. The tail drive and the trailing extent of the cylindrical interface are the only parts of the projectile that engage gun barrel rifling when the projectile is positioned in a gun barrel. | 06-30-2011 |
| 20110155014 | Multi-Component Projectile Rotational Interlock - A projectile has a leading part, a trailing part and a cylindrical interface that interconnects the leading and trailing parts. A non-round aperture having a predetermined longitudinal extent is formed in the trailing end of the leading part and a non-round peg having a predetermined longitudinal extent substantially equal to the predetermined longitudinal extent of the non-round aperture is formed in the leading end of the trailing part. The non-round peg is slideably inserted within the non-round aperture when the leading end of the cylindrical interface abuts the trailing end of the leading part and the trailing end of the cylindrical interface abuts the leading end of the trailing part so that the leading and trailing parts of the projectile rotate conjointly with one another when the projectile is rotating about its axis of rotation. | 06-30-2011 |
| 20100224095 | Reduced Friction Projectile - A projectile includes a leading part formed by a tip, a tip base, and a leading rod. A trailing part includes a main base, a truncate base, and a trailing rod. A leading end of a cylindrical interface abuts an annular shoulder where the tip meets the tip base and a trailing end abuts an annular shoulder where the main base meets the truncate base. The tip base and the truncate base respectively support the leading and trailing ends of the cylindrical interface. A medial extent of the cylindrical interface is unsupported by the leading and trailing rods and is deformed radially inwardly by lands in a barrel when the projectile is fired. The leading and trailing ends of the cylindrical interface maintain contact with the lands and the medial extent does not, reducing friction between the projectile and the barrel without sacrificing spin of the projectile. | 09-09-2010 |
