Abstract
A method for producing a base piece for receiving a primer for a multi-part cartridge case may include producing (e.g., by deforming) an extraction groove for engagement by a firearm ejector. The production of the extraction groove may be before a receptacle for a case jacket of the multi-part cartridge case for receiving a projectile is produced, such as by deforming. A tool arrangement for producing a base piece may be used to produce the base piece.
