High accuracy projectile

A projectile having improved accuracy when fired over long ranges is formed from a monolithic block of a copper alloy. Proceeding from a nose to a heel of the projectile, is a fore portion with arcuate side walls, a body portion of substantially constant cross-sectional area that minimally contacts a rifled gun barrel, a drive band having a diameter effective to seal propellant gases and an aft portion that continuously decreases in diameter terminating at the heel. A cylindrical bore extends from an opened end at the nose to a closed end proximate to a transition plane between the fore portion and the body portion.

Lead free reduced ricochet limited penetration projectile

A frangible projectile with a specific gravity similar to a lead projectile. The projectile comprises 34-94%, by weight, binder. The binder comprises poly ether block amide resin. The projectile further comprises 6-66%, by weight, ballast. The ballast comprises at least one member selected from a group consisting of tungsten, tungsten carbide, molybdenum, tantalum, ferro-tungsten, copper, bismuth, iron, steel, brass, aluminum bronze, beryllium copper, tin, aluminum, titanium, zinc, nickel silver alloy, cupronickel and nickel. The projectile can be prepared with a particularly preferred specific gravity of 5-14 and more preferably 11-11.5.

Longitudinally sectioned firearms projectiles

The present invention relates to longitudinally sectioned bullets and more particularly pertains to a projectile structured to be discharged from a firearm and comprising at least two separable longitudinal body sections and at least one binding element that holds the at least two longitudinal body sections together, such as before impact with a target. Said projectile is thus capable of controlled fragmentation against a soft target. Said projectile is adapted to also contain at least one supplemental payload deliverable to a target.

Large caliber frangible projectile

A large caliber, frangible, training projectile imitates, for training purposes, the corresponding tactical projectile. To enable fragmentation of the training projectile at impact, some embodiments of the frangible projectile are partially or entirely made of a material with a lower yield strength than the material used in the counterpart tactical projectile. Some embodiments of the frangible projectile may include portions that are sectioned, welded, or provided with stress risers. Some embodiments of the frangible projectile may include high density particles suspended in a weaker medium. The fragmentation methods may be applied to the overall mass of the projectile, or to a portion of the projectile.

Projectile

ActiveUS8893621B1Superior flight stability characteristicHighly effectiveAmmunition projectilesTraining ammunitionEngineeringBearing surface
A projectile comprised of an ogive section, a bearing surface section and a boattail section. A cavity is formed inside the projectile from an aperture on the aft end of the boattail section and forward to about the transition point (shoulder) between the ogive section and bearing surface section. The cavity is centered about the centerline of the projectile and open on the aft end of the projectile.

Muzzleloading firearm projectile

A muzzle loading firearm projectile is disclosed that is composed of a multi diameter, hollow base solid copper bullet, the rear cavity filled with a material of low-density, and a gas pressure seal that separates the bullet from the powder charge. The majority of the bullet shank has a diameter less than the bore diameter of the firearm barrel to allow for ease of loading and alignment of the barrel and bullet axis; a narrow ring of material larger than the barrel bore diameter but less than the groove diameter is located at the junction of the bullet shank and nose profile that centers the bullet in the barrel and positively positions the bullet over the powder charge regardless of orientation of the firearm. The low-density material filling the rear cavity of the bullet acts as an expansion medium when impacted by the rear gas seal during the firing process causing the hollow shank of the bullet to expand and lock into the barrel rifling.

Ammunition articles comprising light-curable moisture-preventative sealant and method of manufacturing same

A process for manufacturing an ammunition article, including: (a) providing a cartridge including a projectile disposed in a casing and presenting a joint between the projectile and the casing; (b) applying to the joint a sealingly effective amount of a light-curable sealant composition; and (c) exposing the applied sealant composition to curingly effective light. The resulting ammunition article is sealed at the projectile / casing joint against moisture incursion, and such article is amenable to high-speed, high-volume production by the method of the invention.

Aerially Deployed Illumination System

An aerially deployed illumination system is provided which may be remotely operated or preprogrammed to illuminate a designated target, such as a geographic area, vehicle, or personnel. In particular, a remotely controlled UAV having an illumination system disposed thereon is provided, the illumination system comprised of a concentrated light source and light movement apparatus operable to rapidly scan the target with the light source, thereby providing an illusion of a large area of illumination. Preferably, a line is created from the light source, the line being rapidly moved over the target in specific patterns and at specific frequencies. The system may further include a plurality of UAV's capable of ad hoc networking, so as to illuminate both large areas, as well as stationary and moving targets. In addition, the UAV's having an illumination system disposed thereon may be disposed within a projectile, the projectile tube or gun launched, and the UAV ejected from the projectile over a designated target, thereby enabling quick delivery of the UAV to an area of interest.
