Abstract: A breakable shooting target formed from a composition comprising: a binder component, a binder modifier, a viscosity modifier, and a filler. Carbon black or other pigments can be added for color. The binder can be selected from one or more natural fatty acids. The binder modifier can be selected from one or more metal oxides. The viscosity modifier can be selected from one or more plant based or other natural resins. The filler component can be selected from various powders, such as powdered limestone, other sources of calcium carbonate, talc and so forth.

Abstract: A pressure sensitive bituminous composition having improved tack and adhesiveness, comprising: (1) from about 50% to about 87% of a bituminous component; from about 1 to about 15% of a thermoplastic block copolymer, M.sub.1, of the A-B-A type, preferably styrene-butadiene-styrene; (3) from about 1% to about 10% of a block copolymer, M.sub.2, of the A-B type, preferably styrene-butadiene; and (4) from about 5% to about 50% of a fumed silica. The fumed silica is an active ingredient which absorbs excess oil and improves the tack and adhesiveness of the final composition.
