Case | plastic, light green |
Primer | percussion, flat, brass, battery cup crimp |

Notes | Brass primer holder. Cases were linked with clear plastic tape. The rate of fire for the gun was too high for a reciprocating firing pin. The groove in the case head allowed a fixed firing pin to fire the round as it passed through the action. |
