Abstract

Metallic solid projectile for practice cartridges, in particular for use on preferably police shooting ranges, wherein the solid projectile comprises a front-side ogival portion and a cylinder portion for holding the solid projectile in a cartridge case and defines a projectile length in the axial direction, wherein the ogival portion has an ogival wall and a rotationally symmetrical ogival cavity circumferentially bounded by the ogival wall, wherein it is provided that a fully cylindrical stem portion of the solid projectile extends in the axial direction over less than 45% of the projectile length.

Claims (17)

1. A metallic solid projectile for practice cartridges, comprising a ogival portion at a front side and a cylinder portion for holding the solid projectile in a cartridge case,

the ogival portion having an ogival wall and a rotationally symmetrical ogival cavity circumferentially bounded by the ogival wall,

wherein

starting from a bottom of the ogival cavity, a shaft extends into the cylinder portion, which shaft forms a microchannel having an opening width smaller than 1 mm, and a deformation cavity.

2. The metallic solid projectile according to claim 1 , wherein the ogival wall has an ogival wall thickness and the solid projectile forms an annular deformation sleeve wall in the cylinder portion in the axial direction at least in sections, which has a deformation sleeve wall thickness which is greater than the ogival wall thickness.

3. The metallic solid projectile according to claim 1 , wherein the solid projectile has an opening at the front side which opens into the ogival cavity and has an inner opening diameter which is greater than 0.5 mm.

4. The metallic solid projectile according to claim 1 , wherein the cylinder portion extends in the axial direction over less than 3 mm and/or a calotte is recessed at the rear end of the solid projectile.

5. The metallic solid projectile according to claim 1 , wherein an inner contour surrounding the ogival cavity is completely rounded in the axial direction.

6. The solid projectile according to claim 2 , wherein the ogival wall thickness is less than half of a radius of the solid projectile and/or the deformation sleeve wall thickness is less than or equal to the radius of the solid projectile.

7. The projectile according to claim 1 , wherein the cylinder portion comprises a stem portion extending from the rear side of the projectile to a bottom of the ogival cavity that has a length in the axial direction from the rear side of the projectile to the bottom of the ogival cavity that is less than 45% of the projectile length.

8. The solid projectile according to claim 1 , wherein the shaft extends from a bottom of the ogival cavity through the cylinder portion to a rear end of the projectile opposite the front side or to a calotte recessed at the rear end of the solid projectile.

9. The metallic solid projectile according to claim 1 , wherein the solid projectile is blunt at the front side.

10. The metallic solid projectile according to claim 1 , wherein the deformation cavity is shaped at least in sections to be cylindrical and/or at least in sections to be conical with a taper at the front side or at least in sections conical in shape with a frontal taper and/or heart-shaped.

11. The metallic solid projectile according to claim 1 , wherein the microchannel has a capillary shape with microscopic opening width and a clear width between the opposing microchannel inner sides less than 10 μm.

12. The metallic solid projectile according to claim 2 , wherein the opening at the front side has an inner opening diameter which is greater than 1.0 mm.

13. The metallic solid projectile according to claim 2 , wherein the opening at the front side has an inner opening diameter which is smaller than 3 mm.

14. The metallic solid projectile according to claim 2 , wherein the opening at the front side has an inner opening diameter which is smaller than 1.5 mm.
