Projectile tip

Abstract

A projectile includes a body having rotationally axial symmetry; and a meplat at a tip end of the body. The meplat includes a flat portion defined by a plane that intersects the projectile perpendicularly with respect to a central axis through a lengthwise direction of extension of the projectile, and a chamfered portion defined by a chamfer cut extending from an outer perimeter of the flat portion toward an outer surface of the body.

What is claimed is: 
     
         1 . A projectile, comprising:
 a body having rotationally axial symmetry; and   a meplat at a tip end of the body, the meplat including:
 a flat portion defined by a plane that intersects the projectile perpendicularly with respect to a central axis through a lengthwise direction of extension of the projectile, and 
 a chamfered portion defined by a chamfer cut extending from an outer perimeter of the flat portion toward an outer surface of the body. 
   
     
     
         2 . The projectile according to  claim 1 , wherein the projectile is a bullet of a predetermined caliber. 
     
     
         3 . The projectile according to  claim 2 , wherein a diameter dimension of the flat portion is based on the predetermined caliber of the bullet. 
     
     
         4 . The projectile according to  claim 3 , wherein the diameter dimension of the flat portion ranges from about 0.35 mm to about 0.7 mm. 
     
     
         5 . The projectile according to  claim 3 , wherein the diameter dimension of the flat portion ranges from about 0.35 mm to about 0.45 mm. 
     
     
         6 . The projectile according to  claim 3 , wherein the diameter dimension of the flat portion is 0.4 mm. 
     
     
         7 . The projectile according to  claim 2 , wherein an angle of the chamfer cut is based on the predetermined caliber of the bullet. 
     
     
         8 . The projectile according to  claim 7 , wherein the angle of the chamfer cut ranges from about 51 degrees to about 53 degrees. 
     
     
         9 . The projectile according to  claim 7 , wherein the angle of the chamfer cut is 52.5 degrees. 
     
     
         10 . The projectile according to  claim 2 , wherein a depth of the chamfer cut is based on the predetermined caliber of the bullet. 
     
     
         11 . The projectile according to  claim 10 , wherein the depth of the chamfer cut ranges from about 0.1 mm to about 0.3 mm. 
     
     
         12 . The projectile according to  claim 10 , wherein the depth of the chamfer cut is 0.1 mm. 
     
     
         13 . A bullet, comprising:
 a body having rotationally axial symmetry; and   a meplat at a tip end of the body, the meplat including:
 a flat portion defined by a plane that intersects the projectile perpendicularly with respect to a central axis through a lengthwise direction of extension of the projectile, a diameter dimension of the flat portion being based on a predetermined caliber of the bullet, and 
 a chamfered portion extending from the flat portion. 
   
     
     
         14 . The bullet according to  claim 13 , wherein the diameter dimension of the flat portion ranges from about 0.35 mm to about 0.7 mm. 
     
     
         15 . The bullet according to  claim 13 , wherein the diameter dimension of the flat portion ranges from about 0.35 mm to about 0.45 mm. 
     
     
         16 . The bullet according to  claim 13 , wherein the diameter dimension of the flat portion is 0.4 mm. 
     
     
         17 . A bullet, comprising:
 a body having rotationally axial symmetry; and   a meplat at a tip end of the body, the meplat including:
 a flat portion, and 
 a chamfered portion extending from an outer perimeter of the flat portion toward an outer surface of the body, the chamfered portion having a depth and a cut angle that are each based on a predetermined caliber of the bullet. 
   
     
     
         18 . The bullet according to  claim 17 , wherein the cut angle of the chamfered portion ranges from about 51 degrees to about 53 degrees. 
     
     
         19 . The bullet according to  claim 17 , wherein the cut angle of the chamfered portion is 52.5 degrees. 
     
     
         20 . The bullet according to  claim 17 , wherein the depth of the chamfered portion ranges from about 0.1 mm to about 0.3 mm.
