It has been found that the processing, in particular movement and / or displacement, of iron material causes a change in the hardness of the bullet.

- intermediate 100 and full floor 1 are made of iron material, in particular a CioC Saar steel with a carbon content of more than 0.05%.
- the decisive advantage of the material used is its improved environmental compatibility compared to the bullet materials used up to now, such as lead in particular.
- Fig. 1 an exemplary embodiment of the full projectile 1 according to the invention is shown in side view.
- a direction of flight F is indicated schematically by an arrow and points to the right in FIG. 1.
- the terms bow, bow side, front or front side and stern, stern side or rear side are to be understood.
- full floors 1 according to the invention can be divided into three main sections: a floor bend 3; an adjoining guide band 5; and a projectile tail 7 adjoining the guide band 5.
- the projectile bow has an essentially ogive-like shape and tapers in Direction of flight F with the formation of an ogive 9 to a frontal, flat end face 11 pointing in the direction of flight F, unlike standard known full storeys in which the ogive 9 opens into a projectile tip, which is realized, for example, by reshaping, the flat end face 11 is through Cutting the ogive 9 to length. It has been found that the ogive area flattened in this way and the resulting flat end face 11 have a positive effect on the outer ballistics of the full floor 1 and that significantly lower forces are required in the manufacture of the bow-side ogive, which can be realized, for example, by reshaping.
- the ogive 9 opens at the rear into the guide band 5.
- a curvature of the ogive 9 decreases continuously so that immediately before a transition 13 into the guide band 5, the projectile bow 3 approximates at least a cylindrical shape.

- the guide band 5 defines a maximum outside diameter D a, max of the full storey 1.
- the transition 13 from the guide band 5 to the projectile nose 3 is formed by an external contour recess at which an external diameter D a of the full projectile 1 is suddenly reduced.
- the circumferential outer contour recess is indicated schematically in FIG. 1 by the visible edge identified by the reference number 15.
- the outer contour recess 15 can ensure that essentially only the guide band 5 engages in the pull profile of the gun barrel 15. This is illustrated below with reference to FIGS. 4 to 6.
- the rear guide strip 5 is also radially separated from the projectile tail 7 adjoining the rear.
- a transition 17 from the projectile tail 7 into the guide band 5 is formed by an outer contour projection on which an outer diameter D a of the Full story l continuously enlarged. This is illustrated by the two visible edges 19, 21, which are axially spaced from one another in the longitudinal direction of the storey, between which the outer contour of the full storey 1 widens continuously in the radial direction in the direction of the guide belt 5.
- an inclination angle can with respect to possess an oriented in the longitudinal extension of the full projectile 1 projectile longitudinal axis in the range of io ° to 90 °, as shown in FIG. 1 of the transition 17 in the range of 15 0 is 45 0 while at the junction 13 a 90 0 - outer contour projection is formed by Geunterbug 3 in the guide strip. 5 Furthermore, a radial depth of the outer contour projection or the outer contour recess, which is to be dimensioned transversely to the longitudinal axis of the projectile, is less than 0.5 mm, in particular approximately 0.2 mm.
- the rear outer contour projection from the bullet tail 7 into the guide band 5 has the technical effect of so-called breathing of the gun barrel 15 Gas pressure generates an elastic widening of the firearm barrel 15, as a result of which the full projectile 1 glides more gently within the firearm barrel 15. This means that the press-through resistance is increasingly reduced. It was found that the resulting gases press into the outer contour of the rear contour in the area of the transition 17 and the gun barrel 15 and thus expand the barrel radially elastically, so that there is less abrasion between the gun barrel 15 and the bullet 1.
- the projectile rear has a cylindrical rear section 23 directly adjoining the guide band 5 or the transition 17.
- the cylindrical rear section 23 is adjoined by a projectile base 27 which opens into a floor 25 and tapers concavely in the direction of the floor 25 at least in sections.

It has been found that by providing an intermediate 100 with a concavely tapering front section 105, the forces necessary for forming can be reduced. This made it possible to improve the ballistics of the full floor 1. Deformations on the material, in particular on the iron blank and / or on the intermediate 100, result in local changes in hardness, which have a negative effect on the ballistics. This determined relationship is explained with reference to FIGS. 7 to 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%.
