In order to improve the incendiary effect of munitions the hollow compartment of a projectile body of a shattering and incendiary shell or grenade is provided with an incendiary charge and two explosive charges. The incendiary charge possesses at its rear region or end a substantially funnel-shaped recess or cavity into which there protrudes a substantially conically-shaped tip of the first explosive charge of said two explosive charges.

Shattering and incendiary shell containing a projectile body

The incendiary mass comprises a zirconium or titanium powder containing a mean grain size of 15-50 .mu.m, to which there is added less than 2%-by-weight of an organic binder, in particular polyvinylacetate because small binder concentrations have a favorable effect upon the action or effect pattern of the combusting or burning metal particles, i.e. upon the combustion time and length of the flight trajectory.
