Definitions
- the invention relates to a small-caliber full floor.
- Small caliber bullets are usually made of lead and lead alloys produced, for example, by cutting pieces into pieces cut from a lead wire Matrices are deformed to projectiles.
- Small bore shooting is a sport that is carried out both outdoors and in halls.
- the shooting of Lead bullets produce gases containing lead dust that are harmful to health. Therefore, when shooting in halls, special regulations regarding the Ventilation must be observed.
- the for Lead residues of the projectiles which are harmful to the environment, are collected and disposed of become.
- the measures required when firing lead bullets Protection of people and the environment is complex and expensive.
- a projectile which is made of zinc or Zinc alloys is made.
- the Kem enclosed with a coat tailored to this purpose. For example, if you don't want the story to disassemble, the core is with one Enclosed copper sheath.
- the projectile core is for practice purposes enclosed in a plastic jacket, preferably made of nylon. The rear surface of the The bullet is straight and is only encompassed by the coat at the edge.
- a small-caliber bullet made of a lead-free material is proposed according to the invention, the density of which is> 5 g / cm 3. Because of its density, such a material has sufficient trajectory stability. When firing, there are no toxic pencils and when firing outdoors, the bullet remains do not have to be collected as they do not contaminate the environment.
- the metals tin or zinc or alloys of these two materials belong as particularly suitable materials, which are suitable both in terms of their hardness, their density and their harmlessness to the environment.
- Tin has a density of about 7.2 g / cm 3 and zinc of about 7.3 g / cm 3 .
- the material can also be a plastic, preferably a Thermoplastic that can easily be molded into a projectile by injection molding. Plastics that rot in nature are particularly advantageous. These bullets are eliminated naturally, so that no time-consuming collection is required is required.
- Lead is compared to the materials mentioned for the projectile according to the invention usually softer. Therefore, the deformation of the rear floor causes a good eyebrows.
- Soft lead has a Vickers hardness of around 5 HV. The Vickers hardness of tin is also around 5 HV, while the hardness of pure zinc is 35 HV is.
- depth and Diameter can be matched to the material used. This The depression generally has the shape of a spherical cap. Only an optimal eyelid results a precise shot. The indentation of a storey from the rear lead-free material is therefore usually much more pronounced than in a lead bullet.
- the depression can be hard Make up materials up to 65% of the length of the sleeve holder. This is in the Usually about 3 mm long.
- the sleeve receptacle of the projectile has a sleeve insertion groove on. This is the only way a pinch with a fixed projectile seat and a high Tool life can be achieved. The pinching causes a uniform projectile pull-out force. This has a positive effect on the precision of the Shot and thus on the accuracy.
- the figure shows a small-caliber full floor 1 according to the invention, here from one Zinc alloy, on an enlarged scale.
- the sleeve receptacle 2 has the following differences: by one in the hard Zinc material to achieve optimal lids penetrates the deepening in the form of a Dome 3 from the rear 4 deep into the sleeve receptacle 2. This will make the remaining walls of the sleeve receptacle 2, in particular in the area of the tail 4, thin and therefore light even with zinc as a harder material than lead deformable.
- the calotte 3 From the rear 4 of the floor 1 to the pole 5 of the calotte 3, which on the Axis 6 of the projectile lies, the calotte 3 extends over a depth 7 into the Shell receptacle 2 of the projectile.
- the depth is 7 in the present Embodiment 65% of the total length 8 of the sleeve receptacle 2.
- the sleeve receptacle 2 a sleeve feed groove 10.
- the sleeve edge 11 is in this sleeve insertion groove 10 indented, which causes a sleeve pinch with a fixed projectile seat.
