Abstract
The present invention provides compositions and methods for the coating and/or ballistics conditioning of firearm projectiles and firearm components including gun barrels, firearm chambers, fully assembled cartridges, shot gun shells, shotgun wads, shot capsules and sabots with molybdenum disulfide. The composition comprises powdered molybdenum disulfide suspended in a carrier comprising a volatile solvent and a binder selected from cellulosic-, alkyd- and acrylic-resins. Methods for the conditioning of firearm bores by the formation of a hardened layer comprising a product of the reaction or interaction of molybdenum disulfide with materials in the barrel bore are also disclosed.
Claims39
A composition for ballistic conditioning of firearms, firearm components, and firearm projectiles consisting essentially of a suspension of from 10-100% by weight of powdered molybdenum disulfide and from 0-90% by weight of a solid lubricant selected from graphite and boron nitride in a carrier comprising a volatile solvent and a binder selected from the group consisting of quick-drying cellulosic, alkyd, and acrylic resins, and mixtures thereof.
A method for producing ballistic conditioning copper-clad bullets comprising applying a molybdenum disulfide composition to sheet copper prior to forming said copper sheeting into jackets for said bullets.
Firearm projectiles having a coating of a composition comprising molybdenum disulfide in a binder selected from cellulosic-, alkyd- or acrylic-based resins.
A method of ballistically conditioning the bore of the barrel of a firearm comprising applying to said bore a coating of a composition comprising powdered molybdenum disulfide in a carrier comprising a volatile solvent and a binder selected from the group consisting of quick-drying cellulosic, alkyd, and acrylic resins, and mixtures thereof and thereafter heating said barrel to a temperature sufficient to cause the molybdenum disulfide to react with components of the barrel to form a hardened layer on the surface of said bore.
A firearm having a barrel with a coating on the bore thereof, said coating comprising powdered molybdenum disulfide and a binder selected from a cellulosic-, alkyd- or acrylic-resin.
