Abstract: The present invention relates to a substantially spheroidal fragmentation device (10). The fragmentation device (10) comprises: i) a protective exterior layer (6) of resilient material accommodating at least one warhead (9); ii) an inner core (11) protected by said exterior layer (6). The inner core (11) comprises: ii.a) an insensitive munition (IM); ii.b) a polymeric, plastic and/or rubbery matrix embedding the insensitive munition (IM); ii.c) explosive material (5) enclosed within the matrix of ii.b) and/or surrounding the matrix of ii.b). The ratio of the thickness of the protective exterior layer (6) to the radius of the fragmentation device (10) ranges from 0.1:1 to 0.7:1. The warhead (9) is accommodated within the protective exterior layer (6) or between the inner core (11) and the protective exterior layer (6). The invention also relates to a method of firing a fragmentation device (10) as disclosed herein, wherein a firearm is aimed at a surface enabling rebounding of the fragmentation device (10) whereby the fragmentation device (10) changes direction. The invention also relates to the use of a fragmentation device (10) as disclosed herein in a firearm.
