Composite decoppering additive for a propellant

Abstract

There is provided a decoppering agent that is added to a propellant charge to remove copper from the rifling of the internal bore of a gun barrel. The decoppering agent consists essentially of a lead-free pulverized additive dispersed in a combustible binder. One suitable decoppering agent is pulverized bismuth metal, dispersed in a nitrocellulose binder. The bismuth metal either vaporizes or liquifies when the propellant charge is ignited and either embrittles or dissolves the copper deposits facilitating removal.
