Teilmantelmantel with lead core The invention is a Teilmantelgeschoß for big game. There are known such projectiles whose front part is deformable, while the rear part is a compact mass, which does not deform when impacting on the game body, but acts like an anvil on the front projectile part. As a result, the projectile mass of the front projectile part at the moment of impact suddenly brought to fragmentation, whereby the cross-sectional load drops sharply, while the rear non-deformable part of the projectile mass takes its full coat-like way, which is the hydrodynamic effect detrimental.
There are also fragmentation projectiles are known whose floor mass is indeed deformable, but this process takes place due to high airspeed and interaction with a hollow point in the projectile head, ie the whole projectile mass splinters on impact such that here the Ouerschnittsbelastung suddenly drops, which makes a depth effect impossible ,
Disassembly projectiles are also known whose projectile mass is divided from the outset into several projectiles, which are held together only by the projectile jacket. Upon impact on the game body they are released due to rupture of the projectile shell. However, the projectile only has the character of the bullet shot, eliminating the hydrodynamic depth effect. The known deformation projectiles, in contrast to the aforementioned projectile structures, their projectile mass in the course of the deformation process by splinters. As a result, the projectile mass remains as long as possible, ie the decrease in the cross-sectional load is gradual, whereby a certain depth effect is ensured. Hunting projectiles of this type have the disadvantage that their construction for all caliber remains the same, so that the different or caliber-related deformation resistance is not taken into account. With medium and thicker calibers, this has the consequence that the limited cutting load available for the deformation process also makes only part of the projectile mass effective. So the cost of bullet mass is in the opposite proportion to their effect.
This deficiency is remedied by the game of deer according to the invention and thereby achieves an improvement of the rifle shot with a view to rapid and pain-free Zurstreckebringen of the game.
The drawing illustrates an embodiment of the new big game bullet in view, partly in the vertical center section.
The projectile consists in the main of the lead core and this enclosing coat of Tombak or other suitable material. The tip i of the lead core is not enclosed by the mantle, it is exposed. The rear cylindrical part 2 of the projectile represents the guide caliber. The cylindrical part 3 which precedes this forms the projectile head. He is of smaller diameter than the lead caliber. The diameter of the projectile head can be adapted to the specific purpose of use (strength of the game) in accordance with the guide caliber. Thus, in the course of the deformation process, projectile energy is saved due to reduction of the deformation resistance of the projectile mass from the cross-sectional difference of the guide caliber and the projectile head, which benefits the deformation of the projectile mass of the head as well as the deformation of the guide caliber and its depth effect. The weight ratio of the projectile head to the guide caliber can be 1: 5 to 5: i.
The transition of the two caliber into each other forms a truncated cone 4, which serves for pressure transmission. The jacket 5 of the projectile is thin-walled in the guide caliber, so deliberately undersized. In the vicinity of its bottom he is reinforced by an inner annular bead 6, at which in the screw passage in the opposite direction to the sleeve twist inner reinforcing ribs 7 join. This gives the jacket stability and is in a sense yielding. By this particular kind of reinforcement of the shell when tearing the projectile on the game body, the tearing of the length and premature ejection of Bleikerns are prevented from the torn coat. The depth effect of the projectile can be adapted to the respective intended use by tuning the shell reinforcement.
The interaction of thin-walled and jacket reinforcement in the guide caliber allows by pressure transmission of the two caliber each other and by cutting the Mantelwandung by the trains deformation of the guide caliber already at its front edge, in contrast to the ordinary cylinder projectile, which only after the first third an upset his Projectile column learns. As a result, projectile energy for the deformation process can be saved and projectile mass for the hydrodynamic depth effect and the penetration of the game body in sufficient storey remainder obtained.
In contrast to the known projectile structures, which basically represent only gradations in the fragmentation character, which is dispensed with hydrodynamic depth effect on the assumption that the projectile fragments should be given to the main value, the invention builds on the idea of hydrodynamic depth effect.
