Claims6
Projectile for fire arms, the projectile comprising:
- a front portion of convex axial cross-section over the full axial length thereof that, via a transition portion, transforms into a rear portion of cylindrical radial cross-section, which rear portion acts as a power belt for the projectile, the front portion consisting of:
- an acute portion, the entirety of which having a curved axial cross-section and extending from a front point of the projectile to an area where the front portion has a maximum diameter;
- and
- an intermediate portion, the entirety of which having a curved axial cross-section and extending from the area where the front portion has the maximum diameter to the transition portion, the transition portion extending to the rear portion,
- wherein the transition portion has a curved axial cross-section, and
- wherein the rear portion has a diameter that is equal to the maximum diameter.
