    • PROBLEM TO BE SOLVED: To provide a ballistic mortar testing device having a small damage of a liner, requiring little labor necessary for calibration, and almost dispensing with liner exchange.
      SOLUTION: In this ballistic mortar testing device, the liner 6 in the mortar 1 is formed from a metal material having a tensile strength and an elongation satisfying following expressions (1)-(3), when expressing the tensile strength (N/mm
      2 ) by X, and the elongation (%) of the metal material by Y; expression (1): X≥750, expression (2): Y≥10, expression (3): Y≤-0.07X+140.
