Expanding and/or partially fragmenting bullet

Abstract

The present invention relates to a deformation and/or partial fragmentation projectile comprising a jacket and a two-part core arranged within the jacket and having a projectile front-sided core part and a projectile rear-sided core part, the core being attached to the jacket such that the projectile rear-sided core part is more strongly attached to the jacket than the projectile front-sided core part.

1 . A deformation and/or partial fragmentation projectile comprising a jacket and a two-part core arranged inside the jacket and having a projectile front-sided core part and a projectile rear-sided core part, wherein the core is fastened to the jacket such that that the projectile rear-sided core part is fastened more strongly to the jacket than the projectile front-sided core part. 
     
     
         2 . The deformation and/or partial fragmentation projectile according to  claim 1 , wherein the projectile front-sided core part is attached to the jacket such that that upon impact of the projectile with a target, the projectile front-sided core part can detach from the jacket, and/or the rear core part is secured to the jacket such that upon impact of the projectile with a target, the rear core part remains secured to the jacket. 
     
     
         3 . Deformation and/or partial fragmentation projectile according to  claim 1 , wherein the projectile rear core part is at least 5% stronger, preferably at least 10%, 15%, 20%, 25% or at least 30% stronger, attached to the jacket than the projectile front core part. 
     
     
         4 . Deformation and/or partial fragmentation projectile according to  claim 1 , wherein the projectile rear-sided core part is/are made of lead and/or the projectile front-sided core part is/are made of lead and/or tin. 
     
     
         5 . Deformation and/or partial fragmentation projectile, in particular according to  claim 1 , comprising a jacket and a two-part core arranged inside the jacket and fastened thereto, with a projectile front-sided core part and a projectile rear-sided core part, wherein a connection technique for attaching the projectile front-sided core part to the jacket differs at least in sections from a connection technique for attaching the projectile rear-sided core part to the jacket. 
     
     
         6 . Deformation and/or partial dismantling projectile according to  claim 5 , wherein the connection technology for fastening the projectile front-sided core part and the connection technology for fastening the projectile rear-sided core part to the jacket are based, at least in sections, on different physical principles of action, wherein in particular the core part at the rear of the projectile is fastened to the jacket by a material fit, preferably soldered and/or welded and/or glued to the jacket, and/or the projectile front-sided core part is fastened to the jacket by a form fit and/or force fit. 
     
     
         7 . Deformation and/or partial fragmentation projectile according to  claim 5 , wherein the projectile rear-sided core part is attached to the jacket by means of fusion brazing or diffusion brazing. 
     
     
         8 . Deformation and/or partial fragmentation projectile according to  claim 5 , wherein an outer circumferential surface of the projectile rear-sided core part facing the jacket is joined, in particular to more than 5%, preferably to 100% of a total outer circumferential surface of the projectile rear-sided core part, to a jacket inner surface by material bonding, preferably by brazing. 
     
     
         9 . A deformation and/or partial fragmentation projectile according to  claim 5 , wherein the projectile front-side core part is frictionally secured to the jacket, in particular is pressed into the jacket and/or is clamped in the jacket, and/or is secured to the jacket with the formation of an interference fit, wherein in particular a radial interference between projectile front-side core part and jacket is in the range from 0.001 mm to 0.01 mm. 
     
     
         10 . A deformation and/or partial fragmentation projectile, in particular a hunting projectile, in particular according to  claim 1 , comprising a jacket and a two-part core arranged inside the jacket, preferably made of lead and/or tin, wherein a projectile rear-sided core part is soldered to the adjacent jacket and a projectile front-sided core part is substantially unsoldered, preferably pressed in, with respect to the surrounding jacket. 
     
     
         11 . A method of manufacturing a deformation and/or partial fragmentation projectile formed according to  claim 1 .
