Benefits of technology

The present invention provides a molded metal ammunition projectile with a rounded or blended shape at the nose, a cylindrical bearing surface, and optionally cannelures or other features. The metal composition can include stainless steel, brass, ceramic alloys, copper / cobalt / nickel / custom alloys, tungsten, tungsten carbide, or aluminum. The projectile can be a full metal jacket, expanding full metal jacket, spritzer, jacketed spritzer, armor piercing, or armor piercing incendiary. The base can have a flat or boattail shape. The metal composition can include specific amounts of various elements such as nickel, chromium, molybdenum, cobalt, niobium, titanium, aluminum, or vanadium. The invention provides a molded metal ammunition projectile with improved performance and reliability.

Problems solved by technology

Shortcomings of the known methods of producing projectiles for ammunition include the limitation of materials that can be used to form projectiles and the lengthy time for manufacturing.

Embodiment Construction

[0037]While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.

[0038]As used herein the term “shell,”“bullet” and “projectile” are used interchangeably and denote a projectile that is positioned in an ammunition cartridge until it is expelled from a gun, rifle, or the like and propelled by detonation of a powdered chemical propellant or other propellant that may be non-powdered, solid, gaseous or gelatin. And includes payload-carrying projectiles contains shot, an explosive or other filling, though modern usage sometimes includes large solid projectiles properly termed shot (AP, APCR, APCNR, APDS, APFSDS and proof shot).

Abstract

The present invention provides a molded metal ammunition projectile comprising: a metal composition injected into a molded to form a projectile comprising a nose extending essentially symmetrically to a shoulder; an essentially cylindrical bearing surface extending from the shoulder to a base.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]None.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates in general to the field of ammunition, specifically to compositions of matter and methods of making metal projectiles by metal injection molding.STATEMENT OF FEDERALLY FUNDED RESEARCH[0003]None.INCORPORATION-BY-REFERENCE OF MATERIALS FILED ON COMPACT DISC[0004]None.BACKGROUND OF THE INVENTION[0005]Without limiting the scope of the invention, its background is described in connection with projectiles made by injection molding for use in ammunition. Conventional ammunition projectiles for rifles and machine guns, as well as larger caliber weapons, are made from brass or lead that are machined, cast, molded or coated.[0006]For example, U.S. Patent Application Publication No. 2003 / 0101891 entitled, “Jacketed bullet and methods of making the same” discloses a jacketed firearms projectile having a jacket thickness less than approximately 0.025 inches thick are described, w...
