Abstract
Composite spherical projectiles are provided for shotgun cartridges which are environmentally compatible, relatively inexpensive and have ballistic properties similar to lead shot or projectiles and which consist of metal particles dispersed in a biogradable polymeric solid matrix which includes a hydrocarbon binder containing ester functional groups which are linked to C.sub.1-20 aliphatic hydrocarbon chains, starch, and titanium dioxide.
