Frangible ammunition |
摘要 |
A frangible projectile (1) is provided which has a conical nose (5) with an included angle in the range 40-41 degrees. The conical nose (5) has a forward end (9) which is blunt. The projectile is made from a mixture of a metal powder and a thermoplastic resin of nylon 11. The metal is about 80% by weight and the projectile has a specific gravity in the range 2.35 to 5.7. The projectile exhibits desired ballistic characteristics for distances up to about 150 m and can disintegrate on impact with solid objects. In addition a projectile made according to the preferred embodiment and fitted in a 5.56 mmx45 mm military cartridge case (equivalent to a 0.223 inch Remmington case) charged with a propellant such as type AR2207 (by ADI Ltd.) in the range of 25-26 grains, exhibits particularly suitable characteristics for use in firing ranges.
