A base part for producing a cartridge case, the base part comprising:
- a case base for receiving a primer cap, said case base having a circumferential extractor recess formed therein on an outer circumference of the base part, said circumferential extractor recess having a polygon geometry being formed from a closed traverse in cross section, said case base having a cylindrical portion adjacent said circumferential extractor recess.
A method for producing a cartridge case having a cylindrical case with a case opening formed therein for receiving a propellant charge and a projectile, and also a base part opposite the case opening with a case base for receiving a primer cap, the method comprises the following steps of:
- supplying a base body for producing the cartridge case;
- producing a circumferential extractor recess on an outer circumference of the base body in a form of a polygon geometry forming a closed traverse in cross section.
A method for producing a base part for a cartridge case having a case base for receiving a primer cap, the method comprises the following steps of:
- supplying a cylindrical base body for producing the base part;
- and
- producing a circumferential extractor recess on an outer circumference of the cylindrical base body in a form of a polygon geometry forming a closed traverse in cross section.
