For the Firebird to function, the bullet must first penetrate through the front face of the target. The target must be adhered to a solid flat surface such as plywood, etc.

Reasons for Firebird not to function include:

  • Shooting the target through the rear surface first
  • Target has been improperly stored (damp)
  • Target has not been stuck against a smooth solid surface
  • Bullet has insufficient energy to create detonation
  • Target has not been hit by bullet!
