摘要： THE DISCLOSURE RELATES TO CARTRIDGES FOR GUNS COMPOSED OF A STEEL CARTRIDGE SLEEVE HAVING A TEFLON OR NYLON, ETC., JACKET THEREAROUND TO PREVENT EXCESSIVE FRITION. IN ONE EMBODIMENT OF THE DISCLOSURE, THE SLEEVE IS CLOSED AT THE FRONT END BY A NYLON TOP CAP AND A MAIM CHARGE IS POSITIONED IMMEDIATELY BEHIND THE TOP CAP AND WITHIN THE STEEL SLEEVE. AT THE REAR PORTION OF THE STEEL SLEEVE, THERE IS SPOSITIONED A NYLON END CAP WHICH IS SECURED WITHIN THE SLEDGE, THE END CAP INCLUDING A NEGATIVE ELECTRICAL CONTACT PASSING FROM THE OUTER PORTION THEREOF INTO THE MAIN BODY OF THE SLEEVE AND A POSITIVE ELECTRICAL CONTACT ALSO PASSING THERETHROUGH INTO THE INNER PORTION OF THE SLEEVE. WITHIN THE SLEEVE IS POSITIONED A GLASS OR PLASTIC CAPSULE WHICH ENCLOSES AN EXPLOSIVE COMPOSITION POSITIONED BETWEEN THE POSITIVE AND NEGATIVE CONTACTS. THE CARTRIDGE IS DESIGNED TO CAUSE AN EXPLOSION UPON THE PLACEMENT OF THE VOLTAGE ACROSS THE POSITIVE AND NEGATIVE CONTACTS TO PROJECT THE NYLON TOP CAP OUTWARDLY, THE SPENT SHELL BEING RETAINED IN THE GUN BARREL AND NOT UNDERGOING ANY MOVEMENT.

A SECOND EMBODIMENT OF THE DISCLOSURE SETS FORTH A CARTRIDGE HAVING A TWO-PART SLEEVE AND A STEEL DISC THEREBETWEEN, ONLY THE FORWARD PORTION OF THE SLEEVE BEING PROJECTED UPON EXPLOSIVE WITHIN THE CARTRIDGE, THE OTHER PORTION BEING RETAINED WITHIN THE BARREL OF THE GUN. A THIRD EMBODIMENT OF THE DISCLOSURE SETS FORTH AN ARMOR PIERCING PROJECTILE UNIT WHEREIN A LEADING PROJECTILE IS FOLLOWED BY AN EXPLOSIVE TRAILING PROJECTILE, THE LEADING PROJECTILE PROVIDING AN OPENING FOR THE TRAILING PROJECTILE TO PASS THROUGH AND PROVIDE AN EXPLOSIVE DUE TO INERTIAL IMPACT. AN END CAP, WHICH IS PRROVIDED AS IN PRIOR EMBODIMENTS, FORMS THE WELL KNOWN "DUM-DUM" PROJECTILE AND DROPS FROM THE FLIGHT PATH OF THE OTHER TWO PROJECTILES.
