Abrégé

A projectile 1 for ammunition is diclosed, said projectile 1 comprising an outer profile geometry on an ogive-shaped impact end portion 5 thereof, said outer profile geometry comprising two or more notches 2 extending in at least one of (i) an axial, (ii) parallel or (iii) slightly inclined orientation relative to a dissecting axis 3 extending longitudinally through said impact end portion 5 of said projectile 1, wherein each notch 2 (a) comprises notch surface portions 4,7 so as to increase (i) an overall outer surface area of said ogive end portion 5 of projectile 1, and (ii) a given length of an outer surface periphery Sp extending along a line within a plane normal to said dissecting axis 3, and (b) is surrounded by an outer side surface 51 of said ogive- shaped impact end portion 5 of said projectile 1. In other words, the presence of the two or more notches 2 increases a length of an outer surface periphery Sp extending along a line within a plane normal to said dissecting axis 3 relative to the same outer surface periphery Sp extending within the same plane normal to said dissecting axis 3 when a notch is not present.
