The method of the present invention is a method for producing disposable targets, for example so-called skeets, to be used in shooting sports and other similar purposes. The invention introduces a method for producing skeets made of a material which is firm and cheap and which doesn't cause health complication for men or animals or doesn't cause other damage when it spreads in nature during shooting competitions. These purposes are achieved by a process wherein a compound formed of gypsum containing crystal water (CaSO.sub.4.2H.sub.2 O) with water and possibly other ingredients as impurities in smaller amounts, is mixed with another compound containing some highly water-binding substance, for example calk (CaO), as well as possibly other substances as impurities in smaller amounts, whereafter the resulting mixture is put under high pressure, for example 10kN/cm.sup.2, owing to which pressure the said mixture is instantaneously congealed.
Method for producing a disposable target, usable in shooting sports comprising the steps of mixing CaSO.sub.4.2H.sub.2 O and a CaO containing substance in the form of a second powder to provide a powder mixture thereof, and thereafter subjecting the powder mixture to sufficiently high molding pressure for substantially instantaneously congealing the mixture to solid form to provide such target.
