ABSTRACT:
A cartridge shaped barrel insert is described that can be used as the barrel of a pistol and as a rimfire cartridge insert for a large bore weapon. The cartridge insert includes an internal secondary firing pin that can be actuated to fire a rimfire cartridge by a hammer on the pistol frame or by the usual hammer and center fire mechanism of a large bore weapon. A resilient pad within the insert yieldably urges the secondary firing pin away from the breech end of the barrel. A cap can be placed over the bullet of the rimfire cartridge to match the bore of a large bore center-fire weapon. When the cartridge is fired, the rimfire bullet and cap will be driven by expanding gases along the weapon barrel, with the barrel bore guiding the cap and bullet in the same manner as a conventional large bore bullet.
