摘要： A cartridge for a firearm has a bullet that defines an internal chamber. The chamber has a broader top portion than a lower portion. The bullet further defines a channel passage leading out of the top end of the bullet. The bullet contains an arrowhead slidable engaged within the channel passage. A shaft is connected to the arrowhead and passes down from the arrowhead into the lower portion of the chamber. A thrust plate is connected to the shaft end in the chamber. The thrust plate is spring metal and when the cartridge is fired, the thrust plate rises pushing the arrowhead so that it extends from the leading end of the bullet. When the thrust plate rises to the second portion of the chamber, it springs open to prevent subsequent downward motion of the thrust plate and consequently prevents subsequent retraction of the arrowhead during flight and after impact.
