Abstract
The invention provides an explosive round that produces fragments propelled by jetting effect, the round consisting in a firing head, an explosive charge, a fragment generating wall in direct contact with the explosive, which wall has a set of indentations extending towards the inside of the round and into the explosive, so that each indentation constitutes a shaped charge, wherein the indentations of the fragment-generating portion are in the form of caps extending inside the explosive, each cap presenting a surrounding base having a diameter comprised between 2.5 mm and 5.5 mm and a wall thickness comprised between 0.5 mm and 0.8 mm, so that each cap generates a corresponding fragment propelled by jetting effect, fragment which has no effectiveness beyond 35 m from the point of explosion.
