Abstract
A primer composition with reduced toxicity suited for reduced-energy ammunition comprises bismuth (III) oxide as the principal oxidizer and contains a portion of propellant composition mixed therein. This composition may also be used in a cartridge which is otherwise substantially free of any other propellant compound and preferably produces a residue which is substantially free of toxic substances.
Claims19
A primer composition for use in reduced-energy ammunition primer cup comprising:
- a) a percussion initiated, shock-sensitive primary explosive,
- b) a combustible fuel,
- c) an oxidizer
- characterized by the use of bismuth(III) oxide as the oxidizer and the presence of a further propellant composition mixed with the balance of the primer composition to form the final primer mixture.
