  • a cylindrical iron blank 200 is provided which has predetermined dimensions, for example an axial length of just under 30 millimeters, in particular 28.55 millimeters, and a diameter of less than 5 millimeters, in particular approximately 4.7 millimeters .
  • An intermediate 100 according to the invention (FIG. 8) is first formed from the iron blank 200, in particular formed, preferably cold formed.
  • a concavely tapering front section 105 is formed on the front side, preferably by forming, in particular cold forming.
  • the pre-pressed body 101 produced in this way is then processed further to form a full bullet 1 according to the invention, which is shown in FIG. 9.
  • the iron blank 200 was also processed in such a way that the intermediate 100 according to FIG. 8 has experienced an increase in diameter of approximately 15% and a reduction in length of approximately 5%, so that the intermediate 100, for example, has a length of 27.09 millimeters and a diameter of 5% .4 millimeters.
  • the finished full floor 1 according to FIG. 9 was shortened again by about 9% starting from the intermediate 100, the diameter having increased again by about 5%, so that the Full story, for example, has a length of 24.7 millimeters and a maximum outside diameter D a , max of 5.66 millimeters.
  • the 5.56 mm solid bullet 1 has a mass of 3.88 g. In relation to the originally provided iron blank made of CioC material, this means an overall diameter increase of about 20% and an overall length reduction of about 13.5%.
