US12474145 - Projectile and caseless cartridge

A caseless cartridge including a projectile. A bullet is positioned on a leading end of the projectile and sized to exit a firearm through a barrel of the firearm. An ignition housing is positioned on a trailing end of the projectile opposite the leading end. An ignition source is positioned within the ignition housing. A hollow shaft extends between the bullet and the ignition housing and joins the bullet to the ignition housing. A plurality of ignition ports extend through a wall of the shaft and through the ignition housing. An interior of the shaft is fluidly coupled to an interior of the ignition housing. The ignition source is configured to ignite a propellant through the plurality of ignition ports in response to an activation of the firearm. When the firearm is activated, each component of the caseless cartridge is either consumed or discharged from the firearm through the barrel.
