  • Patent number: 8561542
    Abstract: The invention includes a number of shotgun shells having colored projectiles. When each shooter in a party of shooters utilize shotgun shells which have a projectiles of a color which is uniquely distinctive to that shooter then one is able to determine, by post-shooting inspection of an animate or inanimate target which was fired at by multiple shooters of said party, which of said shooters actually struck the target, how many times and at what place on said target The invention is therefore useful in accurately crediting each shooter for the accuracy of their shooting.

  • Patent number: 7073425
    Abstract: A shot pellet that, has an inner core of a material such tungsten carbide, that is coated with a layer of bismuth. This coating is molecularly bonded to the tungsten carbide and is not an alloy. The unique properties of the shot pellet allow its density to be tailored. Under this process, the effective density of the pellet can be made to be identical to lead for direct replacement in current lead loading formulations. Additionally, the density can be made to be lower than lead for shotguns requiring low barrel pressures, or higher than lead for enhanced energy transfer while maintaining the other advantages of the instant invention.

  • Patent number: 5760331
    Abstract: A projectile, such as a bullet, is made by combining two different metals in proportions calculated to achieve a desired density, without using lead. A base constituent, made of a material having density greater than lead, is combined with a binder constituent having less density. The binder constituent is malleable and ductile metallic phase material that forms projectile shapes when subjected to a consolidation force, such as compression. The metal constituents can be selected, rationed, and consolidated to achieve desired frangibility characteristics.

  • Patent number: 5747724
    Abstract: The invention relates to shot pellets for hunting in wet marshlands or corresponding wet areas. The shot has an inner core of copper or copper alloy and an outer layer of silver or silver alloy. No heavy metal will leach from the shot into the environmental surroundings, and the shot has no toxic effect on birds, even should they ingest a considerable quantity of shot. The shot is produced by granulating copper or copper alloy electrochemically to obtain shot cores, whereafter at least one layer is applied thereto. The outer layer always consists of silver or a silver alloy.

  • Patent number: 5528988
    Abstract: The invention relates to shot pellets for hunting wild game, particularly birds on wet marshlands. The pellets are also suitable for clay pigeon shooting on organized skeet ranges. The shot pellets have an inner core comprised of lead or lead alloy, and an outer layer of silver or silver alloy. The shot pellets are not influenced, or only slightly influenced by a strong hydrochloric acid environment, therewith greatly eliminating the risk of lead leaching from the pellets. The shot pellets are produced by coating shot pellet cores of lead or lead alloy electrochemically with at least one layer, wherein the outermost layer is always comprised of silver or a silver alloy.

  • Patent number: 5095831
    Abstract: A shotgun shell loaded with steel shot utilizes a number of magnetized steel pellets intermixed in the load in order to form clusters of pellets as the load is discharged from the shell to thereby improve the shot pattern of relatively lightweight steel shot, steel being less dense than lead. The magnetized steel pellets may be either randomly mixed throughout the load or concentrated in one or more areas of the load. If concentrated in the middle of the load, a much larger cluster of shot is believed to be expelled from the gun barrel upon discharge of the shell. A Teflon.TM. or the like coating may be applied to the steel shot, or lubricants included in the load in order to lubricate the inside of the barrel and reduce any increased tendency of the magnetized shot to wear or abrate the barrel as the shot is discharged therefrom.

  • Patent number: 4949645
    Abstract: High density materials, e.g. for fishing weights or pellets or shot as ammunition, are composed of a material comprising high-density metal particles in particular tungsten-containing particles, in a settable or hardenable polymeric matrix providing a composite material of stable configuration. Fishing weights may be produced in known forms, or as flexible tubing to be cut to size by the user, or as a hinged pair of body parts which can be closed together to grip a line between them and to be reopened. For pellets or shot similar materials comprising a polymeric matrix can be provided, or such products can be pressed directly from a tungsten alloy. These products all offer particular advantages of non-toxicity, and the fishing weights can be given the ability to be re-used many times.
