Projectable, frangible and environmentally acceptable targets are disclosed which are free of pitch, and which are in all respects environmentally acceptable, and furthermore which can be produced by a simple compacting procedure. The targets are produced from an inert filler component, such as limestone or clay, and a binder component which is capable of binding the inert filler component without being heated to its thermal decomposition point, the inert filler component being friable and relatively wettable with a solvent so that agglomerates of the inert filler component, the binder component, and a solvent can be produced, and a target may then be prepared by compression forming such agglomerates. Methods for producing such targets are also disclosed, including providing a mixture of the inert filler component, the binder component, and the solvent, compacting the mixture into the desired form, and drying by driving off the solvent at a temperature below the thermal decomposition point of the inert filler material.
