ABSTRACT:
A collapsible bullet is provided which rapidly expands upon impact and possesses excellent penetration characteristics. The bullet includes at least two separate parts which form an integrated unit, i.e., a nose part having a central bore therethrough and a base or rear part which includes a central collapse column that projects through the opening in the nose part. The distal end of the collapse column is peened over to help hold the parts together. After initial impact by the leading end of the nose part, successive impacts are produced by the rear part, and any intermediate parts, as these parts are driven into the nose part, thereby causing an outward expansion of the nose part and possible complete penetration of the nose part by the rear part or parts.
