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.

A projectile for fire arms formed in such a way that it includes a front portion of essentially convex axial cross-section that via a transition transforms into a rear portion of essentially cylindrical radial cross-section, which rear portion acts as a power belt for the projectile.

A projectile includes: (a) a cured, toughened polymer resin; and (b) a particulate filler distributed through the resin, the filler having a density greater than a density of the resin, wherein the projectile has average density less than the density of lead.

A projectile includes a head, a tail, and an interface that interconnects the head and tail. Multiple sections of the interface are deformed by being compressed radially inwardly into respective annular recesses formed between the interface and the head and tail during manufacturing or by rifling when the projectile is fired. The amount of deformation is controlled by the depth of each of the annular recesses. In all embodiments, annular ridges formed in the head, the tail, or both, define the longitudinal extent of the annular recesses. The interface includes an annular obturation region and has a beveled open leading end to facilitate insertion of the head and tail into the interface.

An intercept device for flying objects made of a light-weight, packable structure made of a pliable, tear resistant material that can be expanded to a large web-like structure by means of a deployment device, into the path of a flying weapon. To capture, hold and reduce the velocity of intercepted flying objects, activatable resistance bodies are incorporated into uniformly distributed masses that are connected to the perimeter of the web like structure. Contractable sections of the web, made of cable-like structures, connected to perimeter masses, act as drawstrings upon collision with flying object. This causes closure of the web around the flying object as a result of the mass's inertia and added resistance from deployable resistance structures that place tension on drawstring structures of the web. The flying object is subsequently captured within the web, held secure and it's velocity rapidly reduced.

A large caliber, frangible, training projectile imitates, for training purposes, the corresponding tactical projectile.

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.

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.

A reusable paint dispersing grenade of the type employed in paint ball games is constructed in such a manner as to avoid the use of any combustible materials, and also to avoid the requirement for access to a source of compressed air for operation. The paint grenade of the invention has a hollow, fluid-tight casing defining an enclosed cavity that is divided internally into a marking paint chamber, a first propellant component chamber, and a second propellant component chamber. The propellant component chambers are each filled separately with propellant components, but remain isolated from each other until the paint dispersing grenade is used. At that time the propellant components chemically react with each other in a noncombustible manner to produce a quantity of gas under pressure. The expanding gas produced by the chemical reaction builds to a pressure sufficient to break a paint seal in the casing or a gas seal initially separating the gas from the paint, whereupon the gas under pressure forces the paint out through one or more paint expulsion ports. The device may be recharged with marking paint and the chemically reactive propellant components any number of times.
