Abstract: The invention relates to a method for expanding a bullet and to a bullet for implementing the method. The bullet comprises a cylindrical body and a conically convergent point. A cavity filled at least partly with a filling agent is arranged to extend from the point towards the base of the bullet. When such a bullet hits and penetrates a target, force action is directed to the bullet to turn the point of the bullet towards the direction opposite to the direction of travel of the bullet. To slow this, the filling agent is extended outside the cavity in the area of the bullet point. As the bullet with such a cap moves on in the target, the filling agent slowly presses into the cavity guided by the sealing surface releasing the point of the bullet.
