PROBLEM TO BE SOLVED: To provide an ammunition including a bullet and a cartridge that enable abnormal increasing of inner pressure of the cartridge to be restricted.SOLUTION: A bullet 10 comprises: a first fitting segment 13 fitted at an extremity end cylinder 21 of a cartridge 20 to tightly close the inside of the cartridge 20; a second fitting segment 14 stored at the base end side in the cartridge 20 from the extremity end cylinder 21 and fitted to the extremity end cylinder 21 when the bullet 10 passes through the extremity end cylinder 21; and a communicating shaft segment 15 for communicating between the first fitting segment 13 and the second fitting segment 14. This communicating shaft segment 15 is extended from an outer circumferential surface of the first fitting segment 13 to the rear side to have a longer clearance 17 than an axial length of the extremity end cylinder 21 between it and an annular communicating surface 16 communicated with the outer circumferential surface of the second fitting segment 14. |
