    為何擊中目標後還能燃燒 ?

    This is 2 questions here.......

    1.) What is the different of an incendiary bullet?

    Traditional Full Metal Jacket (FMJ) Bullet have a fully jacket metal projectile, usually a copper wrap around with a lead projectile. When the bullet travel though air, fiction burn off the copper and thus allow the lead projectile to penetrate the target realtively intact.

    Incendiary bullet also have copper wrapping, instead of warpping a lead projectile, they were wrapped around a hollow point projectile. With the hollow point filled with inflammable fuel or explosive material. The copper protected the projectile from fiction though air and allow the projectile to enter target intact.

    Actually, ideally, an incendiary bullet will ONLY START BURNING WHEN THEY IMPACT THE TARGET.

    When an incendiary projectilt hit a target, the content of the hollow point expand with high pressure (Imagint how large the pressure are when the bullet hit something travelling with 1000 meter per second

    This ignite the explosive content inside the projectile and start burning, and it will keep burning until the material are all gone and there are no fuel left. The theory is similar to how a bullet fire, when the hammer hit the primer.

    Cos of this nature, an incendiary bullet will have a minimum distance to take effect, under that distance, the projectile will not burn and it will be just like a normal FMJ, with less power..
