    • PROBLEM TO BE SOLVED: To raise the trajectory performance while maintaining the external form capable of being charged into a gun used currently, by forming the rear of a bullet in the shape of a hemisphere continuous from the front of the bullet. SOLUTION: A bullet 1 is made in egg form out of a conical front 11 made by a slow parabola, and a hemispherical rear 12 continuous from this, and this is set with an explosive shell 2 charged with a required quantity of bursting charge 21. When the bullet 1 breaks away from the explosive shell 2 and is discharged from the muzzle, the air positioned a little apart from the bullet 1 flows along the upper part of the front 11 of the bullet, and also turns to the rear 12 of the bullet, and flows while narrowing the rear flow 150, with the position slid to rearward from a largest-diameter part 13, and reduces pressure resistance. Accordingly, the bullet flies in stable posture, and also this can raise the trajectory distance.
